DOI: 10.3897/dez.71.111874

Abstract: Here, we describe a new genus of lice (Phthiraptera, Ischnocera) in the Oxylipeurus-complex, parasitising galliform hosts in the genera Tragopan Cuvier, 1829. This genus, Pelecolipeurus gen. nov., is separated from other members of the complex by the unique shape of the male subgenital plate and stylus, the male genitalia and other characters. The only previously-known species in the genus is Lipeurus longus Piaget, 1880, which is here tentatively re-described as Pelecolipeurus longus (Piaget, 1880), based on specimens from a non-type host, Tragopan temminckii (Gray, 1831). In addition, we describe a new species, Pelecolipeurus fujianensis sp. nov., based on specimens from Tragopan caboti (Gould, 1857). An overview of the distribution patterns of ischnoceran lice on galliforms is presented, which suggests that host phylogeny, host biogeography and host biotope, as well as elevation of host range, may all be important factors that have structured louse communities on landfowl. We transfer the genus Afrilipeurus from the Oxylipeurus-complex to the Lipeurus-complex and include an emended key to the Oxylipeurus-complex.

Two new species of the genus Agramma (Hemiptera, Heteroptera, Tingidae) from small islands of Japan, with an illustrated key to the Japanese species of the genus https://dez.pensoft.net/article/108270/ Deutsche Entomologische Zeitschrift 71(1): 49-65

DOI: 10.3897/dez.71.108270

Authors: Jun Souma

Abstract: The present study describes two new species of the monocotyledon-feeding lace bugs of the genus Agramma Stephens, 1829 (Hemiptera, Heteroptera, Tingidae, Tinginae, Tingini) from small islands of Japan. The first is A. (A.) izuense sp. nov., which was recorded as A. (A.) japonicum (Drake, 1948) from Hachijo Island, the Izu Islands, in a previous study, and is considered an independent species here based on morphological characteristics and molecular data. The second is A. (A.) keramense sp. nov., which has a remarkable spineless head and was discovered from Aka and Geruma islands, Kerama Group, the Ryukyu Islands. Consequently, the following four species of Agramma were recognized in Japan: A. (A.) abruptifrons Golub, 1990, A. (A.) izuense sp. nov., A. (A.) japonicum, and A. (A.) keramense sp. nov. Only dozens of submacropterous morphs were confirmed in these two species in the present study, suggesting that both new species are flightless. In addition, an illustrated key for the identification of the four species from Japan and the host plant relationships of the two new species are provided.

Comparative morphology of the larval mouthparts among six species of Notodontidae (Insecta, Lepidoptera), with discussions on their feeding habits and pupation sites https://dez.pensoft.net/article/107431/ Deutsche Entomologische Zeitschrift 70(2): 357-368

DOI: 10.3897/dez.70.107431

Authors: Jia-Xin Liu, Lu Jiang

Abstract: Larval mouthparts are significant organs for the individual development, morphologically related with feeding habits, and providing valuable characters for taxonomy and phylogenetic analysis. In previous studies, larval mouthparts revealed two identifying characters of Notodontidae. However, the evolutionary driving force and exact definition of these structures remain unsatisfactory. In this study, the larval mouthparts of Euhampsonia cristata (Butler, 1877), Fentonia ocypete (Bremer, 1861), Phalera assimilis (Bremer & Grey, 1853), Nerice davidi Oberthür, 1881, Cerura erminea (Esper, 1783) and Furcula furcula (Clerck, 1759) are morphologically observed and compared using scanning electron microscopy (SEM). The larval mouthparts of the six species are commonly equipped with paired maxillary sacs, congruent with the previous descriptions. However, the larval mouthparts of N. davidi are peculiar for bearing toothed mandibles, providing an exception of Notodontidae. Otherwise, the mouthparts exhibit morphological differences on mandibles, spinnerets, labral notches, and setal arrangements among the six species. The morphological diversity and the related feeding and pupation habits are briefly discussed.

Phylogeny of genus Sichuana Shen & Yin, 2020 (Orthoptera, Tettigoniidae, Tettigoniinae) with four new species from Sichuan, China https://dez.pensoft.net/article/105870/ Deutsche Entomologische Zeitschrift 70(2): 337-355

DOI: 10.3897/dez.70.105870

Authors: Jun-Jie Gu, Chengjie Zheng, Su-Rong Jiang, Yanli Yue

Abstract: Four new species of Sichuana Shen & Yin, 2020 are described based on morphological comparison and molecular analysis: S. planicercata sp. nov., S. curvicercata sp. nov., S. longilamina sp. nov. and S. magnicerca sp. nov. Specimens showed some intraspecific variation of male tegmina and subgenital plates. The genes COI and 16S were used to analyze the genetic distance between species and COI was used to analyze the phylogenetic relationship of Sichuana.

Explosive radiation versus old relicts: The complex history of Ethiopian Trechina, with description of a new genus and a new subgenus (Coleoptera, Carabidae, Trechini) https://dez.pensoft.net/article/107425/ Deutsche Entomologische Zeitschrift 70(2): 311-335

DOI: 10.3897/dez.70.107425

Authors: Arnaud Faille, Sylvia Hofmann, Yeshitla Merene, David Hauth, Lars Opgenoorth, Yitbarek Woldehawariat, Joachim Schmidt

Abstract: The trechine beetle fauna (Coleoptera, Carabidae) of the Ethiopian Highlands is known to be highly diverse in species, and many species groups were recognized to be characterized by unusual character states of external and genital morphology. Earlier authors described several genera and subgenera of Ethiopian Trechina endemic to certain high mountains of the country. However, the relationships of these species groups and their evolutionary history are unknown so far. Here, we present the first molecular phylogenetic analysis of Ethiopian Trechina, detect several synonymic names under Trechus sensu lato, and introduce two new species groups to the country’s fauna: the monotypic genus Baehria Schmidt & Faille, gen. nov., with the type species B. separata sp. nov. from Mt. Choke in northern Ethiopia, and the Trechus subgenus Abunetrechus Schmidt & Faille, subgen. nov., with the type species T. bipartitus Raffray, 1885; this subgenus includes three species of northern Ethiopia. We show that the composition of the Ethiopian fauna is based on multiple events of immigration, which started simultaneously with or some million years after the Oligocene-Early Miocene orogenic events north and south of the Rift Valley. Our results support the habitat island hypothesis for the evolution of the Ethiopian highland fauna. We found no evidence for an alternative hypothesis assuming a close connection of the Trechina immigration to Ethiopia and Pleistocene cooling. We, thus, conclude that the geomorphological development rather than the climatic changes are the main drivers of the diversification of the high-altitude Trechina fauna in Ethiopia.

A morphology-based revision and phylogenetic analysis of the Pterostichus macrogenys species group (Coleoptera, Carabidae) and implications for differentiation of the species group https://dez.pensoft.net/article/107322/ Deutsche Entomologische Zeitschrift 70(2): 291-310

DOI: 10.3897/dez.70.107322

Authors: Kôji Sasakawa, Yoshiji Mitsuduka

Abstract: The Pterostichus macrogenys species group is an endemic subterranean Japanese carabid clade that provides intriguing material for studying morphological differentiation, speciation and interspecific relationships. However, its diversity remains not fully explored. We investigated specimens from northern Tohoku District, an area where knowledge of this species group is notably limited. Our research led to the description of three new species: P. namahage sp. nov., P. kamurosanus sp. nov. and P. atsumidakensis sp. nov. We also updated distribution records for three known species: P. asahinus Habu & Baba, 1960; P. kitakamisanus Sasakawa, 2005; and P. chokaisanus Sasakawa, 2009. This report includes both the expanded distribution ranges of the known species and the discovery of a new sympatric species pair (P. chokaisanus and P. asahinus). We conducted a morphological phylogenetic analysis of all but one species, for which no male specimens were available, accounting for a total of 42 species within the group. The resulting phylogenetic tree implies that the initial differentiation of this species group originated on the Sea of Japan side, in the northern part of their current distribution, followed by dispersion to other areas and subsequent differentiation. Additionally, our findings indicate that sympatric species of varying body sizes are distantly related phylogenetically. These insights into the differentiation process align with regional distribution patterns of species-level diversity and sympatric sites.

An “American” silkmoth endemic to Himalayas, part I: life history and natural distribution of Antheraea compta Rothschild, 1899 (Lepidoptera, Saturniidae) https://dez.pensoft.net/article/102952/ Deutsche Entomologische Zeitschrift 70(2): 261-282

DOI: 10.3897/dez.70.102952

Authors: Zhengyang Liu

Abstract: Females of the uncommon Antheraea compta Rothschild, 1899 were collected at the natural habitat in the Tibetan Sub-Himalayas, descendants of which were reared on Quercus yunnanensis (Fagaceae) successfully, with all the preimaginal instars recorded morphologically. Correlated characters revealed a close relationship between this taxon and New World Antheraea spp., suggesting more attention and protection towards this key species is necessary in the future.

The snakeflies of the Mediterranean islands: review and biogeographical analysis (Neuropterida, Raphidioptera) https://dez.pensoft.net/article/101559/ Deutsche Entomologische Zeitschrift 70(1): 175-218

DOI: 10.3897/dez.70.101559

Authors: Horst Aspöck, Ulrike Aspöck

Abstract: The Mediterranean region representsone of the hotspots of biodiversity of many organisms and among these also of Raphidioptera. With about 250 known species world-wide Raphidioptera is the smallest order of extant holometabolous insects. The Mediterranean region harbors 113 species (= >45% of the world fauna), and of these 33 (= >13% of the world fauna) have been found on islands of the Mediterranean Sea. In the course of the past 50 years most of the larger islands have been intensively explored for Raphidioptera, particularly all islands (except the Baleares) which had no connection to the mainland throughout the whole Pleistocene. Altogether, 11 species of Raphidioptera (9 Raphidiidae, 2 Inocelliidae) are endemic to (usually)one, rarely to a few Mediterranean islands: Phaeostigma (Ph.) euboica (Euboea), Ph. (Aegeoraphidia) prophetica (Rhodes), Ph. (Ae.) karpathana (Karpathos), Ph. (Ae.) biroi (Crete), Ph. (Superboraphidia) minois (Crete), Subilla principiae (Sardinia), S. colossea (Rhodes), Raphidia (R.) peterressli (Chios), R. (R.) ariadne (Crete), Fibla (F.) maclachlani (Corsica, Sardinia, Sicily), F. (Reisserella) pasiphae (Crete). In the Aegean Sea there is a remarkable difference between the eastern and the western islands marked by the so-called Rechinger line based on results of the analysis of the flora. The Raphidioptera confirm this line impressively. It is rather unlikely that further Raphidioptera species endemic to Mediterranean islands are still to be detected – with one exception: the Baleares. A few additional species known from various parts of the continents surrounding the Mediterranean Sea will probably be found on islands so that a total number may be around 40, possibly around 45 species. The possible ways and times of colonization of the islands by Raphidioptera are discussed. The present paper may serve as a basis for studies on natural and particularly on anthropogenic dispersals of snakeflies from island to island, from mainland to islands, and from islands to the mainland in connection with phylogeographic investigations.

The genus Anacaena Thomson from the Ryukyu Archipelago of Japan (Coleoptera, Hydrophilidae) https://dez.pensoft.net/article/96994/ Deutsche Entomologische Zeitschrift 70(1): 143-157

DOI: 10.3897/dez.70.96994

Authors: Yûsuke N. Minoshima, Yuuki Kamite, Martin Fikáček

Abstract: We review the genus Anacaena Thomson, 1859 from the Ryukyu Archipelago, southern Japan. Three aquatic species are recognised: A. torikaii sp. nov. from Amami-ôshima Island, A. okinawana sp. nov. from Okinawa-jima Island and Kerama Islands, and A. kumejimana sp. nov. from Kumejima Island. All three species are very similar, with the morphology of the aedeagus being essential for a reliable identification. Dorsal colouration is also useful as a diagnostic character, despite some variation within species. We observe a possible geography-based variation between A. okinawana from Okinawa-jima I. and the neighbouring Kerama Is., but we treat both populations as conspecific based on genital morphology. Anacaena kumejimana and A. okinawana share many morphological characters possibly indicating their close relationship. We compare the endemism of aquatic Hydrophilidae in the Ryukyu Archipelago to that in other groups of aquatic beetles: the proportion of endemic species is higher in aquatic Hydrophilidae than in Dytiscidae, but much lower than in stream-inhabiting Hydraenidae and Elmidae. A list of Japanese species of Anacaena and a key to the Japanese species of the genus are provided.

Caribbean pygmy jumping leaves (Tetrigidae, Cladonotinae, Choriphyllini) https://dez.pensoft.net/article/98982/ Deutsche Entomologische Zeitschrift 70(1): 129-141

DOI: 10.3897/dez.70.98982

Authors: Josip Skejo, Sheyla Yong, Domagoj Bogić, Niko Kasalo

Abstract: The tribe Choriphyllini Cadena-Castañeda & Silva, 2019 consists of only two genera, Choriphyllum Serville, 1838 and Phyllotettix Hancock, 1902b, combining leaf-like Caribbean wide-nosed pygmy grasshoppers (Tetrigidae, Cladonotinae). The genus Choriphyllum has four species, C. bahamense Perez-Gelabert & Otte, 1999 from the Bahamas (Hummingbird Cay Island), and C. sagrai Serville, 1838, C. saussurei Bolívar, 1887 and C. wallaceum Skejo, Kasalo & Yong, sp. nov. from Cuba. The gender of C. bahamensis is changed to C. bahamense in order to match the grammatical gender of the genus, which is neuter. Silva’s designation of C. sagrai, the type species of Choriphyllum, as nomen dubium in 2019 was incorrect as Serville’s drawing clearly points to this species, endemic to Cuba, so nothing about its identity is doubtful. The genus Phyllotettix is endemic to Jamaica, where four species live: P. rhombeus (Felton, 1765), P. foliatus (Hancock, 1902a), P. compressus (Thunberg, 1815) and P. plagiatus (Walker, 1871), comb. nov. of Choriphyllum plagiatum. Choriphyllum westwoodi Hancock, 1902a, syn. nov. is synonymous with Phyllotettix rhombeus and not with P. compressus. A new subgenus is established, Phyllotettix (Rhombotettix) subgen. nov. for P. (R.) plagiatus comb. nov. and P. (R.) rhombeus. A new species complex, Phyllotettix (compressus) sp. complex nov. is established for two morphologically close species, P. compressus, and P. foliatus; while another new species complex, Choriphyllum (sagrai) sp. complex nov. includes C. sagrai and C. wallaceum sp. nov. An annotated key to genera, subgenera, species groups and species is provided.

Revisionary notes on Feuerborniella Vaillant, 1971, with the first record of the genus from the Afrotropical region (Diptera, Psychodidae) https://dez.pensoft.net/article/97465/ Deutsche Entomologische Zeitschrift 70(1): 121-127

DOI: 10.3897/dez.70.97465

Authors: Gunnar Mikalsen Kvifte, Santiago Jaume-Schinkel

Abstract: We establish a diagnosis for Feuerborniella Vaillant, 1971, based on a re-description of its type species, Feuerborniella obscura (Tonnoir, 1919) and comment on earlier diagnoses. Feuerborniella sinefurcata Kvifte & Jaume-Schinkel, sp. nov. is described, based on material from Tanzania, representing the second Afrotropical species of the genus following Psychoda morogorica Wagner & Andersen, 2007 which we treat as Feuerborniella morogorica comb. nov. We furthermore review earlier combinations, transferring Philosepedon ensiger Quate, 1996 and Philosepedon longistylus Quate, 1996 to Feuerborniella comb. nov., and briefly discuss generic limits with Quatiella Botosaneanu & Vaillant, 1970 and Nielseniella Vaillant, 1971.

Revision of the genus Eotrechus Kirkaldy (Hemiptera, Heteroptera, Gerridae), with descriptions of six new species https://dez.pensoft.net/article/97117/ Deutsche Entomologische Zeitschrift 70(1): 69-111

DOI: 10.3897/dez.70.97117

Authors: Anh Duc Tran, Herbert Zettel, Robert W. Sites

Abstract: Species of the Asian genus Eotrechus Kirkaldy, 1902 (Hemiptera, Heteroptera, Gerromorpha, Gerridae, Eotrechinae) are atypical water striders because they live on the near-vertical rock surfaces of waterfalls. The taxonomy of the genus is revised and six new species are described: E. steineri sp. nov., E. kerberos sp. nov., E. thai sp. nov., E. konkakinh sp. nov., E. boukali sp. nov., and E. anderseni sp. nov. Supplementary descriptions of the apterous female and macropterous male of E. fuscus Basu, Chandra & Venkatesan, 2017 are provided. Additional and updated distribution data of species of Eotrechus are reported. Eotrechus fuscus is reported from Myanmar for the first time; E. brevipes is reported from Nepal for the first time; E. hygropetricus Andersen, 1982 is reported from southern Thailand for the first time, which extends the southernmost limit of the known distribution of the genus. A revised key to the species of Eotrechus is also provided.

Mouthpart palp sensilla of basal Trichoptera families https://dez.pensoft.net/article/98752/ Deutsche Entomologische Zeitschrift 70(1): 55-68

DOI: 10.3897/dez.70.98752

Authors: Kseniia T. Abu Diiak, Vladimir D. Ivanov, Stanislav I. Melnitsky, Mikhail Yu. Valuyskiy, Alexandra A. Puyto

Abstract: A comparative SEM study of palp sensory surfaces in 25 caddisfly species representing seven families reveals seven types of sensilla: long trichoid, blunt chaetoid, campaniform, mushroom-like pseudoplacoid, petaloid, thick basiconic and thin basiconic sensilla. Long trichoid and chaetoid sensilla are present on all segments of both pairs of palps. First and second segments of maxillary palps bear groups of long and sclerotised chaetoid sensilla on their medial surface. Other segments of maxillary palps and all segments of labial palps have shorter and thinner chaetoid sensilla mainly on their ventromedial surfaces. Campaniform sensilla usually occur on the first segment of labial palps and second segment of maxillary palps. Mushroom-like pseudoplacoid sensilla may occupy all palp segments or only distal ones. Petaloid sensilla form sensory fields on apical segments of both pairs of palps in most studied species. Thick basiconic sensilla occur only in apical sensory complexes on tips of maxillary and labial palps. A comparison with the Lepidoptera suggests the similarity in palp sensilla and conservative evolution of the palp surface. The reconstructed ground plan for the palp sensory surfaces in Trichoptera and Amphiesmenoptera is provided.

Integrative taxonomy of the Lauraceae-feeding species of the genus Stephanitis (Hemiptera, Heteroptera, Tingidae) from Japan https://dez.pensoft.net/article/89864/ Deutsche Entomologische Zeitschrift 69(2): 219-281

DOI: 10.3897/dez.69.89864

Authors: Jun Souma

Abstract: Stephanitis Stål, 1873 (Hemiptera, Heteroptera, Tingidae, Tinginae, Tingini) is one of the most diverse lace bug genera in East Asia with over 50 species, many of them feeding on Ericaceae and Lauraceae. The Japanese species feeding on Lauraceae have high intraspecific and poor interspecific variation, so identification of some previous distribution records (mainly S. (Norba) aperta Horváth, 1912 and closely related taxa) is doubtful. In the present study, 5,080 specimens of Lauraceae-feeding species of Stephanitis from Japan were identified to species based on morphology, and DNA barcodes of the mitochondrial cytochrome c oxidase subunit (COI) region for 53 of those individuals were also obtained. The combined morphological and molecular evidence dataset showed that 10 species of Stephanitis feed on lauraceous trees in Japan: S. (Stephanitis) ambigua Horváth, 1912, S. (Norba) aperta, S. (N.) exigua Horváth, 1912, S. (N.) hayashii sp. nov., S. (N.) hiurai Takeya, 1963, S. (N.) ishikawai sp. nov., S. (N.) mendica Horváth, 1912, S. (S.) tabidula Horváth, 1912, S. (S.) takeyai Drake & Maa, 1955 and S. (S.) tomokunii sp. nov. Additionally, a new synonymy, S. (S.) fasciicarina Takeya, 1931, syn. nov. with S. (S.) tabidula, is proposed, a key for identifying the 10 species is provided and their distribution ranges and host plant relationships are presented.

Taxonomy and nomenclature of some Fennoscandian Sawflies, with descriptions of two new species (Hymenoptera, Symphyta) https://dez.pensoft.net/article/84080/ Deutsche Entomologische Zeitschrift 69(2): 151-218

DOI: 10.3897/dez.69.84080

Authors: Andrew Liston, Marko Mutanen, Mikk Heidemaa, Stephan M. Blank, Niina Kiljunen, Andreas Taeger, Matti Viitasaari, Veli Vikberg, Saskia Wutke, Marko Prous

Abstract: While working on an identification guide to the sawflies of Fennoscandia, we encountered numerous taxonomic problems, for some of which we present solutions. Dicrostema Benson, 1952 is a new synonym of Phymatoceropsis Rohwer, 1916, and not congeneric with Paracharactus MacGillivray, 1908. Two species occurring in Europe are transferred to Phymatoceropsis. Dolerus aericepsellus Heidemaa and Mutanen sp. nov. and Heptamelus viitasaarii Liston, Mutanen and Prous sp. nov. are described from Finland. Abia brevicornis Leach, 1817 nom. rev. is the valid name of Abia nitens auct. nec Linnaeus, and Abia nitens (Linnaeus, 1758) is the valid name for what has recently been called Abia sericea (Linnaeus, 1767). Tenthredo haemorrhoidalis Fabricius, 1781 is treated as an unplaced species of Hymenoptera, possibly Ichneumonoidea. Calameuta variabilis (Mocsáry, 1886) is the valid name of the species recently generally called C. haemorrhoidalis. Claremontia confusa (Konow, 1886) sp. rev. and Claremontia brevicornis (Brischke, 1883) are distinct species. Dolerus coracinus (Klug, 1818) is the valid name for D. anthracinus auct. Dolerus anthracinus (Klug, 1818) is a valid species similar to D. nitens Zaddach, 1859. Dolerus coruscans Konow, 1890 sp. rev. is a valid species. Dolerus junci (Stephens, 1835) is the valid name for Dolerus cothurnatus auct. Dolerus timidus (Klug, 1818) sp. rev. is distinguished from the similar D. pratensis (Linnaeus, 1758). A neotype is designated for Astatus punctatus Klug, 1803. Lectotypes are designated for 39 nominal species. 29 species group names are new junior synonyms. We present data on some species recently collected for the first time in Finland, including first records for the Palaearctic and West Palaearctic.

A redefinition of Umbrageocoris with new species and new combinations (Heteroptera, Lygaeoidea, Geocoridae) https://dez.pensoft.net/article/85584/ Deutsche Entomologische Zeitschrift 69(2): 139-150

DOI: 10.3897/dez.69.85584

Authors: Péter Kóbor

Abstract: The geocorine (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae) true bug genus Umbrageocoris Kóbor, 2019 is redefined based on new morphological information from newly acquired specimens. Two new species are described: U. boonei sp. nov. from continental Indomalaya and U. malipatili sp. nov. from Australia; two new combinations are proposed: U. elegantulus (Distant, 1904), comb. nov., and U. woodwardi (Malipatil, 1994), comb. nov. (both transferred from Geocoris Fallén, 1814). Keys, diagnoses, and distribution data to the discussed species are provided. Hypotheses on the origin of Umbrageocoris and its relationship to other geocorine genera in the region are formulated. New country records: U. elegantulus (Papua New Guinea), U. maai maai (Thailand, Laos) and U. woodwardi (Papua New Guinea).

Review of the genus Sericocampsomeris Betrem, 1941 (Hymenoptera, Scoliidae) from China https://dez.pensoft.net/article/83335/ Deutsche Entomologische Zeitschrift 69(2): 125-138

DOI: 10.3897/dez.69.83335

Authors: Hua-Yan Chen, Zhen Liu, Zheng Wang, Sheng-Jie Yang, Shi-Xiao Luo

Abstract: The Chinese species of the genus Sericocampsomeris Betrem, 1941 are revised, based on morphology. Four species are recognised, of which one species is described as new, i.e. Sericocampsomeris punctata Liu & Chen, sp. nov., for which we also provide molecular sequence data to supplement its identity. A key to species of Sericocampsomeris from China and a distribution map are provided. Furthermore, we identify Sericocampsomeris punctata Liu & Chen, sp. nov. as a pollinator of Elaeocarpus sp. (Elaeocarpaceae) and recognise Leucopholis rorida (Fabricius, 1801) as a host of Sericocampsomeris rubromaculata (Smith, 1855).

Identity of Zorotypus juninensis Engel, 2000, syn. nov. revealed: it is conspecific with Centrozoros hamiltoni (New, 1978) (Zoraptera, Spiralizoridae) https://dez.pensoft.net/article/83154/ Deutsche Entomologische Zeitschrift 69(1): 65-70

DOI: 10.3897/dez.69.83154

Authors: Petr Kočárek, Ivona Horká

Abstract: Zorotypus juninensis Engel, 2000, was previously diagnosed based on the external morphology of female and male specimens without description of the male copulatory organ, which is an important character for classification in Zoraptera. Based on a detailed morphological study of the Zorotypus juninensis Engel, 2000 type collections deposited in the American Museum of Natural History in New York, and based on the comparison with the holotype male of Centrozoros hamiltoni (New, 1978), we have determined that these two species are conspecific. We therefore formally synonymize Zorotypus juninensis Engel, 2000, syn. nov. with Centrozoros hamiltoni (New, 1978). Morphological characters and phylogenetic relationships of Centrozoros Kukalova-Peck & Peck, 1993 are also discussed in this report.

Character analysis and descriptions of Eocene sphodrine fossils (Coleoptera, Carabidae) using light microscopy, micro-CT scanning, and 3D imaging https://dez.pensoft.net/article/79931/ Deutsche Entomologische Zeitschrift 69(1): 19-44

DOI: 10.3897/dez.69.79931

Authors: Joachim Schmidt, Stephan Scholz, Kipling Will

Abstract: Of the 12 specimens of Calathus-like sphodrine beetles presently known from Baltic and Rovno amber deposits, 11 specimens were investigated using light microscopy, micro-CT scanning, and 3D imaging techniques. For the first time, many significant diagnostic characters of the external morphology and male and female genitalia of Eocene Sphodrini were studied in detail. Based on these data, three fossil species are diagnosed and placed in a natural group characterized by a derived pattern in elytral chaetotaxy and microsculpture and therefore the genus Quasicalathus Schmidt & Will, gen. nov. is described to comprise these species. Due to the presence of a styloid right paramere, Quasicalathus gen. nov. is considered a member of the sphodrine “P clade” of Ruiz et al. (2009). However, given the absence of synapomorphies of any species group of the P clade, the systematic position of Quasicalathus gen. nov. within this clade remains unresolved. The Baltic amber species Calathus elpis Ortuño & Arillo, 2009 is redescribed based on additional, fossil, non-holotype material and transferred to Quasicalathus gen. nov. Identification of the additional C. elpis fossil material remains slightly uncertain due to the non-availability of the holotype for direct comparison coupled with doubts regarding the accuracy of certain character states presented in its original description. Two species are newly described: Quasicalathus agonicollis Schmidt & Will, sp. nov., from Baltic amber, and Q. conservans Schmidt & Will, sp. nov., from Rovno amber.

Limnomma, a new genus of Ommatidae from the Middle Jurassic Daohugou beds (Coleoptera, Archostemata) https://dez.pensoft.net/article/71880/ Deutsche Entomologische Zeitschrift 68(2): 299-308

DOI: 10.3897/dez.68.71880

Authors: Yan-Da Li, Erik Tihelka, Hong Pang, Di-Ying Huang, Chen‑Yang Cai

Abstract: The relictual archostematan beetle family Ommatidae attained high diversity during the Mesozoic. Despite their once high taxonomic diversity and morphological disparity, many Mesozoic ommatid taxa remain poorly understood, partly due to limited preservation. Here we report an exceptionally well-preserved fossil, which we describe as a new ommatid genus and species, Limnomma daohugouense gen. et sp. nov., from the mid-Jurassic Daohugou Lagerstätte in Northeast China. The new genus can be most easily distinguished from other ommatids by the presence of a circular non-tuberculate region on ventrite 5. The new taxon is discussed in relation to the classification of the Mesozoic genera Brochocoleus and Burmocoleus.

A third species of the rare ant genus Rotastruma (Hymenoptera, Formicidae) from Cambodia, with illustrated generic diagnoses and key to species https://dez.pensoft.net/article/63478/ Deutsche Entomologische Zeitschrift 68(2): 225-233

DOI: 10.3897/dez.68.63478

Authors: Shingo Hosoishi, Seiki Yamane, Heng Sokh

Abstract: The myrmicine genus Rotastruma is a rarely collected arboreal ant group and only two species, R. recava Bolton and R. stenoceps Bolton, are known from the Oriental Region. A new species, R. epispina sp. nov., is described from Cambodia based on the worker and queen castes. The new species is distinguished from R. recava and R. stenoceps by having the propodeal spine directed upwards and elongated peduncle of the petiole. Herein, we provide an update to the identification key and diagnostic characters for the genus Rotastruma.

Morphology, pollen preferences and DNA-barcoding of five Austrian species in the Colletes succinctus group (Hymenoptera, Apidae) https://dez.pensoft.net/article/55732/ Deutsche Entomologische Zeitschrift 68(1): 101-138

DOI: 10.3897/dez.68.55732

Authors: Katharina Zenz, Herbert Zettel, Michael Kuhlmann, Harald W. Krenn

Abstract: Most species of the Colletes succinctus group sensu Noskiewicz, 1936 are taxonomically uncertain. This study has chosen an integrative approach, including pollen analysis, morphology, male genitalia, morphometry, cuticle sculpture and DNA-barcoding (CO1) to investigate the five species that were reported from Austria. It includes a detailed analysis of the male genitalia and the first description of the C. pannonicus male. A syntype male from the island of Crete was designated as the lectotype of Colletes succinctus brevigena Noskiewicz, 1936 to fix the species identity. New distinguishing characters were found: in females the shape of the dorsal end of the fovea facialis and, in both sexes, the structure of maxillary palpi, as well as the different puncturation on the mesopleura. Unknown structures on sterna and genitalia of the males proved to be reliable morphological characters. An identification key is provided for all studied species. Morphometry of females did not allow a clear distinction of species. CO1 sequencing confirmed previous studies that only C. collaris clearly deviates from the other species, including C. pannonicus that was analysed for the first time. Pollen analysis showed polylectic, as well as oligolectic, pollen-collecting behaviour. The collected pollen of C. pannonicus confirmed the field observations that this species is strictly oligolectic on Tripolium pannonicum. Due to pronounced intraspecific variation, it is assumed that the species of the C. succinctus group are either species in statu nascendi or very young species. Therefore, it remains important to include ecological data in species identification.

Philibaetis gen. nov., a new genus from the Philippines (Ephemeroptera, Baetidae) https://dez.pensoft.net/article/59462/ Deutsche Entomologische Zeitschrift 68(1): 1-20

DOI: 10.3897/dez.68.59462

Authors: Thomas Kaltenbach, Jhoana M. Garces, Jean-Luc Gattolliat

Abstract: Investigations of type material and new material from the Philippines (Luzon) revealed that Baetis luzonensis Müller-Liebenau, 1982 and B. realonae Müller-Liebenau, 1982 do not belong to Baetis Leach, 1815. A new genus, Philibaetis gen. nov., is described to accommodate both species and both are re-described based on larvae. The new genus is characterised by having a rectangular labrum with a submarginal row of long, simple setae on the dorsal surface and ventrally on lateral margins long, simple, spine-like setae, on anterolateral margins long, feathered setae and medially long, bifid setae and a partial, submarginal row of lanceolate setae. Both mandibles have blade-like incisors and dorsally, a mediolateral patch of long, spine-like setae; additionally, the left mandible has a tuft of long, partly branched setae at the base of the subtriangular process. Philibaetis gen. nov. is further characterised by a hypopharynx with a medial tuft of stout setae and anterolaterally, two smaller tufts of stout setae, a galea-lacinia with the distal denti-seta tooth-like and directed against canines, a fore femur apically with stout setae, both on anterior and posterior side and without a femoral patch and a claw with one row of denticles and two or three subapical setae. The protogonostyli under the cuticle of male last instar larvae are folded in the Labiobaetis type, excluding their affiliation to the genus Baetis. COI sequences were obtained from both species. The genetic distance (Kimura 2-parameter) between them is 17.5% on average. Very limited genetic distances of 0% to 3% (0.75% on average) were found between specimens of P. luzonensis comb. nov.

A DNA barcode library for ground beetles of Germany: the genus Agonum Bonelli, 1810 (Insecta, Coleoptera, Carabidae) https://dez.pensoft.net/article/56163/ Deutsche Entomologische Zeitschrift 67(2): 197-207

DOI: 10.3897/dez.67.56163

Authors: Michael J. Raupach, Karsten Hannig, Jérome Morinière, Lars Hendrich

Abstract: The ground beetle genus Agonum Bonelli, 1810 is a large genus of the tribe Platynini with many species that show high amounts of intraspecific variations, making a correct identification challenging. As part of the German Barcode of Life initiative, this publication provides a comprehensive DNA barcode library for species of Agonum that are reported for Germany. In total, DNA barcodes from 258 beetles and 23 species were analysed using the Barcode of Life Data System (BOLD) workbench, including sequences from former studies and 68 newly-generated sequences. The neighbour-joining analyses, based on K2P distances, revealed distinct clustering for all studied species, with unique Barcode Index Numbers (BINs) for 15 species (65%). BIN sharing but distinct clustering was found for three species pairs: Agonum micans/Agonum scitulum, Agonum impressum/Agonum sexpunctatum and Agonum duftschmidi/Agonum emarginatum. The given dataset and its analysis represent another important step in generating a comprehensive DNA barcode library for the ground beetles of Germany and Central Europe in terms of modern biodiversity research.

Phylogeny and classification of the genus-group taxa of Loxandrina (Coleoptera, Carabidae, Abacetini) https://dez.pensoft.net/article/55985/ Deutsche Entomologische Zeitschrift 67(2): 151-182

DOI: 10.3897/dez.67.55985

Authors: Kipling Will

Abstract: Bayesian and parsimony phylogenetic analyses of combined and partitioned datasets of molecular (partial sequences of 28S, wg, COI, and CAD) and morphological (51 characters of adults) data for exemplar taxa of five outgroup and 76 ingroup abacetine carabids resulted in a monophyletic Loxandrina Erwin & Sims, 1984 that is split into Australian and American clades. The genus Loxandrus LeConte, 1853 as previously delimited is not monophyletic relative to numerous genus-level taxa in Abacetini Chaudoir, 1873 and is restricted to a subgenus of North American species. A reclassification and nomenclatural changes for the subtribe that are consistent with the phylogeny are provided. Three genera are removed from Loxandrina: Aulacopodus Britton, 1940 moved to Pterostichini Bonelli, 1810; Cosmodiscus Sloane, 1907 and Tiferonia Darlington, 1962 moved to Abacetina. Based on the phylogenetic relationships and nomenclatural priority only four genera are recognized in Loxandrina: Cerabilia Laporte, 1867, Zeodera Laporte, 1867, Pediomorphus Chaudoir, 1878, and Oxycrepis Reiche, 1843. All other previously recognized genera are treated as subgenera. The classification change created eight secondary homonyms that are resolved by the proposal of the following: Oxycrepis gebi, replacement name for O. balli (Straneo, 1993); O. amatona, replacement name for O. matoana (Straneo, 1993); O. xiproma, replacement name for O. proxima (Straneo, 1993); O. rasutulis, replacement name for O. suturalis (Straneo, 1993); O. laevinota, replacement name for O. laevicollis (Bates, 1871); O. arvulap, replacement name for O. parvula (Straneo, 1951); O. noaffine, replacement name for O. affinis (Straneo, 1991); O. alutona, replacement name for O. notula (Tschitschérine, 1901). An overview of the morphological characteristics and diagnostic features of Loxandrina taxa is provided. A key and habitus images are provided for identification of genera and subgenera. The possible historical biogeography of the group is discussed in light of their phylogenetic relationships and past geological events.

Molecular taxonomy of Tomares hairstreaks (Lepidoptera, Lycaenidae, Theclinae) https://dez.pensoft.net/article/50252/ Deutsche Entomologische Zeitschrift 67(1): 19-33

DOI: 10.3897/dez.67.50252

Authors: Vazrick Nazari, Wolfgang ten Hagen

Abstract: Tomares hairstreaks comprise about 10 species distributed from Europe and North Africa to Central Asia. The taxonomy of the genus is hampered by the absence of diagnostic characters by which specimens can be unambiguously assigned to species. Our investigation of morphology and DNA barcode variations within and between Tomares species shows that while well-defined species (T. ballus, T. mauritanicus, T. callimachus, T. desinens and T. fedtschenkoi) diverge, poorly characterized taxa (T. nogelii, T. nesimachus, T. dobrogensis, T. romanovi and T. telemachus) show very little to no differentiation in mtDNA. We reinstate Tomares callimachus spp. hafis (Kollar, 1849) as a valid subspecies (stat. rev.) and propose taxa telemachus Zhdanko, 2000 and uighurica Koçak, Seven & Kemal, 2000 as synonyms of T. romanovi and T. nogelii nogelii respectively (syn. nov.). We relegate Polyommatus epiphania Boisduval, 1848, recently revived as a valid subspecies of T. callimachus, back to synonymy under the latter, and reconsider the status of T. nogelii dobrogensis (Caradja, 1895) in the light of new molecular data. We use a nuclear gene (EF-1α) in addition to COI barcodes to reconstruct the phylogeny of the group.

Species composition and diagnoses of leaf- and fruit-scarring beetles (Coleoptera, Chrysomelidae) infesting bananas and plantains (Zingiberales, Musaceae) in the Indian subcontinent https://dez.pensoft.net/article/47447/ Deutsche Entomologische Zeitschrift 66(2): 179-202

DOI: 10.3897/dez.66.47447

Authors: Kaniyarikkal D. Prathapan, Janakiraman Poorani, S. Amritha Kumari, C. Anuradha, Balakrishnan Padmanaban, Ramalingam Thanigairaj

Abstract: Leaf- and fruit-feeding chrysomelids (Coleoptera) on bananas and plantains (Musaceae, Zingiberales) cause major losses to banana growers in the northern and northeastern regions of India, Bangladesh, and other parts of Southeast Asia. The species composition of these beetles has not been studied so far in India and wrong names or wrong name combinations in the literature have caused confusion. Most particularly, the Central and South American apecies of Colaspis hypochlora Lefèvre (Chrysomelidae, Eumolpinae) has been erroneously reported as occurring in India and Bangladesh, and this name has been used for the Indian species. Based on extensive surveys for leaf- and fruit-feeding chrysomelids in the northern and northeastern regions of India from 2015 to 2019, three species of banana-feeding chrysomelids, namely, Basilepta subcostata (Jacoby) (Eumolpinae), Bhamoina varipes (Jacoby), and a new species, Sphaeroderma cruenta sp. nov. (Galerucinae, Alticini), are documented. Of these, the latter two are recorded as pests of banana in India for the first time. An illustrated diagnostic account of these three species is given to facilitate their identification by economic entomologists. COI sequences of populations of B. subcostata from Assam and Uttar Pradesh showed 98–100% homology, indicating that these populations are conspecific and that COI sequences can be used for rapid species determination. Brief notes on the biology and available management options for these pests are also given.

First known larva of omicrine genus Psalitrus d’Orchymont (Coleoptera, Hydrophilidae) https://dez.pensoft.net/article/34300/ Deutsche Entomologische Zeitschrift 66(1): 107-118

DOI: 10.3897/dez.66.34300

Authors: Yûsuke N. Minoshima

Abstract: The larval morphology of the water scavenger beetle Psalitrus yamatensis Hoshina & Satô, 2005 is described based on a specimen collected from Fukuoka Prefecture, Kyushu, Japan. This is the first description of the larval morphology of the hydrophilid genus Psalitrus d’Orchymont, 1919, as well as the first description of larval chaetotaxy of the tribe Omicrini. Species-level identification of the larva was performed using DNA barcoding of a molecular marker: a 658 bp fragment of the mitochondrial cytochrome oxidase I. A description including chaetotaxy of head capsule and head appendages, diagnosis, and illustrations of the larva is provided. Psalitrus larvae can be distinguished from other known larvae of the tribe Omicrini by the morphology of the head and legs. The larva shares characters with other known larvae of Omicrini; potential plesiomorphies are shared with Cylominae and aquatic hydrophilids; some characters are also shared with larvae of Megasternini and Sphaeridiini.

The Rubens morph of Formica exsecta Nylander, 1846 and its separation from Formica fennica Seifert, 2000 (Hymenoptera, Formicidae) https://dez.pensoft.net/article/34868/ Deutsche Entomologische Zeitschrift 66(1): 55-61

DOI: 10.3897/dez.66.34868

Authors: Bernhard Seifert

Abstract: A study of numeric morphology-based alpha-taxonomy (NUMOBAT) considering the species Formica exsecta Nylander, 1846 and F. fennica Seifert, 2000 was performed in 166 nest samples with 485 worker individuals originating from 117 localities of the Palaearctic west of 59°E. The presence of intraspecific pilosity dimorphism is shown for F. exsecta. The setae-reduced phenotype, termed the Rubens morph, shows a frequency of about 25%, and the more abundant setae-rich phenotype, termed the Normal morph, one of 75%. The frequency of nests containing workers of both phenotypes is 15.5% in 58 samples from Denmark, Sweden, and Finland. Applying the DIMORPH test of Seifert (2016) on this territory, it is demonstrated that the association of Rubens and Normal phenotypes within the same nest cannot be interpreted as parabiosis of independent species (p=0.017) or as temporary (p=0.0004) and permanent (p=0.0001) socially parasitic association, whereas genetically mediated intraspecific dimorphism is most likely (p=0.659, all p data according to Fisher’s exact test). The Rubens morph of F. exsecta is phenotypically most similar to F. fennica but is safely separable by four different forms of exploratory data analyses using nest centroids (NC) as input data: NC-Ward, NC-part.hclust, NC-part.kmeans, and NC-NMDS-k-means. Data on zoogeography and the narrow climate niche indicate that F. fennica is unlikely to occur in Norway.

About Notiophilus Duméril, 1806 (Coleoptera, Carabidae): Species delineation and phylogeny using DNA barcodes https://dez.pensoft.net/article/34711/ Deutsche Entomologische Zeitschrift 66(1): 63-73

DOI: 10.3897/dez.66.34711

Authors: Michael J. Raupach, Karsten Hannig, Jérome Morinière, Lars Hendrich

Abstract: The genus Notiophilus Duméril, 1806 is a distinctive taxon of small, diurnal and morphologically similar beetles exhibiting large eyes and widened second elytral intervals. In this study we analysed the effectiveness of DNA barcodes to discriminate 67 specimens that represent 8 species of Notiophilus from Central Europe. Interspecific K2P distances below 2.2% were found for N. biguttatus (Fabricius, 1779) and N. quadripunctatus Dejean, 1826, whereas intraspecific distances with values > 2.2% were revealed for N. rufipes Curtis, 1829. An additional phylogenetic analysis of all available species revealed a close relationship of N. directus Casey, 1920, N. semistriatus Say, 1823, N. simulator Fall, 1906 and N. sylvaticus Dejean, 1831, possibly indicating a radiation of these species in North America. Low support values of most other nodes, however, do not allow additional phylogenetic conclusions.

Redescriptions of thirteen species of chewing lice in the Brueelia-complex (Phthiraptera, Ischnocera, Philopteridae), with one new synonymy and a neotype designation for Nirmus lais Giebel, 1874 https://dez.pensoft.net/article/32423/ Deutsche Entomologische Zeitschrift 66(1): 17-39

DOI: 10.3897/dez.66.32423

Authors: Daniel R. Gustafsson, Lucie Oslejskova, Tomas Najer, Oldrich Sychra, Fasheng Zou

Abstract: Thirteen species of chewing lice in the Brueelia-complex are redescribed and illustrated. They are: Brueelia blagovescenskyi Balát, 1955, ex Emberiza schoeniclus (Linnaeus, 1758); B. breueri Balát, 1955, ex Chloris chloris (Linnaeus, 1758); B. conocephala (Blagoveshchensky, 1940) ex Sitta europaea (Linnaeus, 1758); B. ferianci Balát, 1955, ex Anthus trivialis (Linnaeus, 1758); B. glizi Balát, 1955, ex Fringilla montifringilla Linnaeus, 1758; B. kluzi Balát, 1955, ex Fringilla coelebs Linnaeus, 1758; B. kratochvili Balát, 1958, ex Motacilla flava Linnaeus, 1758; B. matvejevi Balát, 1981, ex Turdus viscivorus Linnaeus, 1758; B. pelikani Balát, 1958, ex Emberiza melanocephala Scopoli, 1769; B. rosickyi Balát, 1955, ex Sylvia nisoria (Bechstein, 1792); B. vaneki Balát, 1981, ex Acrocephalus schoenobaenus (Linnaeus, 1758); Guimaraesiella haftorni (Balát, 1958) ex Turdus iliacus Linnaeus, 1758; G. lais (Giebel, 1874) ex Luscinia megarhynchos (Brehm, 1831). Redescriptions are made from type material where available. Holotypes are identified in Balát’s material when possible, and lectotypes are designated for B. blagovescenskyi, B. breueri, B. glizi, B. ferianci, B. kluzi, B. kratochvili, B. pelikani, and B. rosickyi; a neotype of Nirmus lais Giebel, 1874 is designated. Brueelia weberi Balát, 1982, is placed as a synonym of Brueelia conocephala (Blagoveshchensky, 1940).

Playing hard to get: two new species of subterranean Trechini beetles (Coleoptera, Carabidae, Trechinae) from the Dinaric Karst https://dez.pensoft.net/article/31754/ Deutsche Entomologische Zeitschrift 66(1): 1-15

DOI: 10.3897/dez.66.31754

Authors: Roman Lohaj, Teo Delić

Abstract: Almost 200 years of continuous and systematic research in subterranean habitats of the Dinaric Karst and adjoining areas have resulted in the discovery of more than 400 specialized subterranean beetles. Among these, a special place belongs to the morphologically well distinguished and elusive, so called aphaenopsoid trechine beetles, which are characterized by a prolonged head, pronotum and appendages, and widened, ovoid-shaped elytra. Two new species of aphaenopsoid trechines – Derossiella lukici sp. n. from two deep pits on Mt Biokovo, Croatia, and Adriaphaenops petrimaris sp. n. from Pištet 4 Cave, Kameno more, Montenegro – are described, illustrated, and compared with closely related congeners. Identification keys for both genera and an annotated catalogue for all Adriaphaenops species, as well as data on the distribution and the ecology of these remarkable species, are provided and discussed.

Review of the flower-inhabiting water scavenger beetle genus Cycreon (Coleoptera, Hydrophilidae), with descriptions of new species and comments on its biology https://dez.pensoft.net/article/26261/ Deutsche Entomologische Zeitschrift 65(1): 99-115

DOI: 10.3897/dez.65.26261

Authors: Emmanuel Arriaga-Varela, Sin Yeng Wong, Alexander Kirejtshuk, Martin Fikácek

Abstract: The hydrophilid genus Cycreon Orchymont, 1919, previously known from two historical specimens only, is reviewed based on the numerous material collected recently from the inflorescences of various Araceae species in the Malay Peninsula and Borneo. Four species are recognized in the genus: C. sculpturatus Orchymont, 1919 from Sumatra, C. armandi Shatrovskiy, 2017 from Singapore, C. adolescens sp. n. from peninsular Malaysia, and C. floricola sp. n. with two subspecies, the nominotypical one from Peninsular Malaysia, and C. floricola borneanus subsp. n. from Borneo. All species are very similar, differing only by the pronotal punctation, shape of the clypeus and the mentum, and the form of the median lobe of the aedeagus. Specimens of C. floricola sp. n. and C. adolescens sp. n. were collected from inflorescences of various genera of the family Araceae. The field observations and analysis of mid gut contents indicates that they feed on organic material on internal organs of the inflorescences, including the pollen of the host plant. They were also observed to carry a large amount of pollen and are likely pollinators of their host species of Araceae.

Revision of the genera Microplitis and Snellenius (Hymenoptera, Braconidae, Microgastrinae) from Area de Conservacion Guanacaste, Costa Rica, with a key to all species previously described from Mesoamerica https://dez.pensoft.net/article/5276/ Deutsche Entomologische Zeitschrift 62(2): 137-201

DOI: 10.3897/dez.62.5276

Authors: Jose L. Fernandez-Triana, James B. Whitfield, M. Alex Smith, Robert Kula, Winnie Hallwachs, Daniel Janzen

Abstract: The genera Microplitis and Snellenius (Hymenoptera: Braconidae, Microgastrinae) from Area de Conservacion Guanacaste (ACG), Costa Rica, are revised. A total of 28 new species are described: 23 of Snellenius (the first record for Mesoamerica) and five of Microplitis. A key is provided to all new species and five species of Microplitis previously described from Mesoamerica. In ACG, all Microplitis were reared exclusively from Sphingidae, while all Snellenius were reared from Noctuoidea (Noctuidae and Erebidae). All of the wasp species with known host records are unambiguously specialists, parasitizing one or a few related hosts. Biological information (wasp cocoon and caterpillar hosts) in the Neotropical region seems to differ from similar data reported in previous works for the Oriental region -but more studies on the world fauna are needed. Although the distinction between these two genera has been controversial, we consider that the available evidence, although not conclusive, suggests that these two genera are best kept as separate (based on the presence of at least a partial epicnemial carina in Snellenius, which is absent in Microplitis). The following 28 species, all authored by Fernández-Triana & Whitfield, are described as species nova: Microplitis adrianguadamuzi, M. alexanderrojasi, M. francopupulini, M. hebertbakeri, M. jorgehernandezi, Snellenius billburgeri, S. bobdressleri, S. donstonei, S. felipechavarriai, S. gerardoherrerai, S. irenebakerae, S. isidrochaconi, S. johnkressi, S. jorgecampabadali, S. jorgegomezlauritoi, S. josesarukhani, S. kerrydresslerae, S. lucindamcdadeae, S. luisdiegogomezi, S. mariakuzminae, S. mariamartachavarriae, S. phildevriesi, S. quiricojimenezi, S. robertoespinozai, S. sandyknappae, S. velvaruddae, S. vickifunkae, S. warrenwagneri.

The Dilaridae of the Balkan Peninsula and of Anatolia (Insecta, Neuropterida, Neuroptera) https://dez.pensoft.net/article/5199/ Deutsche Entomologische Zeitschrift 62(2): 123-135

DOI: 10.3897/dez.62.5199

Authors: Ulrike Aspöck, Xingyue Liu, Horst Aspöck

Abstract: Basing upon all available information on type material of Dilar turcicus Hagen, 1858, Dilar syriacus Navás, 1909, and Dilar lineolatus Navás, 1909, together with a large number of dilarid specimens, the pleasing lacewings of Anatolia and Southeast Europe are revised. The current taxonomic concept of D. turcicus is confirmed, and a lectotype is designated. Dilar turcicus is widely distributed in the southeast of Europe (being the only representative of Dilaridae in this region), in Anatolia, and, most probably, in the Caucasus region. Dilar syriacus and D. lineolatus remain nomina dubia. Dilar syriacus might occur in Anatolia, while D. lineolatus is a species occurring in western Central Asia. Two new species, Dilar anatolicus sp. n. and Dilar fuscus sp. n. are described from Anatolia. Wings and genital segments of the three species occurring in Anatolia are illustrated, and a map documenting the known distribution of these species is provided.

The immature stages and biology of two Xenapates species in West Africa (Hymenoptera, Tenthredinidae) https://dez.pensoft.net/article/4688/ Deutsche Entomologische Zeitschrift 62(1): 9-17

DOI: 10.3897/dez.62.8922

Authors: Andrew D. Liston, Georg Goergen, Frank Koch

Abstract: The immature stages and host plants of Xenapates Kirby, 1882 were hitherto unknown. We describe the larvae, prepupae and pupae of X. braunsi (Konow, 1896) and X. gaullei (Konow, 1896), and record observations on aspects of their biology. The relationship of Xenapates to other taxa currently placed in the Allantinae and Blennocampinae of the Tenthredinidae remains unclear. Most larval characters of Xenapates resemble those described for West Palaearctic Allantini (Allantinae) and some Blennocampinae, but unique amongst exophytic larvae of Tenthredinoidea is the complete absence of cuticular appendages on the dorsum of the trunk in the two Xenapates species studied. The setose outer surface of the abdominal prolegs of Xenapates, and the presence of a mesal ridge only on the left mandible, are character states that have not so far been recorded in other genera currently placed in the Allantinae or Blennocampinae. Larval host plants of X. braunsi are Digitaria horizontalis, Pennisetum purpureum, Setaria barbata and Zea mays (all Poaceae). X. gaullei larvae feed on two Commelina species (Commelinaceae). Larvae of both species are easy bleeders.

Abstract: The identity of Eulachnus cembrae Börner, 1950, stat. rev. from Europe, treated as a synonym of E. pumilae Inouye, 1939 from East Asia is clarified based on characters of sexual morphs. The oviparous female and alate male forms of E. pumilae are described and figured in detail for the first time and the poorly known sexual forms of E. cembrae are redescribed and figured in detail as well. Sexual morphs of the two similar species are compared, and significant differences clearly distinguishing those species are presented. A key to the identification of oviparous females and males of E. cembrae and E. pumilae as well as notes on host plants and distribution of these species are provided. The status of E. pumilae in the European aphid-fauna is clarified. Morphological characters of the sexual generation that may be useful for species identification are discussed.

DOI: 10.3897/dez.61.8142

Authors: Jens Prena, Runzhi Zhang

Abstract: Nine species of Parallelodemas Faust are reported from China. In addition to the previously recorded P. impar Voss, we found P. docile Faust, P. vicinum Faust and the following six species newly described herein: P. dimetans sp. n., P. feae sp. n., P. petilum sp. n., P. plumosum sp. n., P. setifrons sp. n. and P. tumens sp. n. Parallelodemas tarsale Voss from Java is transferred to Lepidomyctides Yoshihara and Morimoto (comb. n.). Lectotypes are designated for P. docile, P. imperfectum Faust, P. perfectum Faust, P. tardum Faust and P. vicinum. Several morphological modifications with unknown functions are documented, illustrated and discussed. Males of some species have special setae on rostrum, antennal scape and mesotarsus. A medially notched epistome apparently occurs in both sexes but seems to wear off in females, probably during the preparation of oviposition sites. The mandible is unusual in having a convex, edentate inner face and incisor-like structures on the outer face.

Two new related oodine genera in the Oriental Region, with remarks on the systematic position of the genera Hololeius and Holosoma (Coleoptera, Carabidae) https://dez.pensoft.net/article/4076/ Deutsche Entomologische Zeitschrift 61(2): 87-104

DOI: 10.3897/dez.61.7754

Authors: Borislav Gueorguiev

Abstract: Two new genera of Oodini LaFerté-Sénectére, 1851 are described: Bamaroodes gen. n. (type species: Hololeius cyaneus Facchini, 2011) for Bamaroodes cyaneus (Facchini, 2011), comb. n., here placed in tribe Oodini and removed from Chlaeniini Brullé, 1834; and Thaioodes gen. n. (type species: Thaioodes piceus sp. n.) for Thaioodes piceus sp. n. (type locality: Khon Kaen, Thailand). The new genera are closely related and belong to the same lineage as evidenced by the following combination of characters: body shape semi-elongate; discal setiferous pore lacking in interval 3 of elytra; mesocoxa without lateral seta; tarsomere 5 setose ventrally; joints of the claws of tarsomere 5 parallel, situated closely to each other. The two genera are readily distinguished from one another by a number of distinct characters. Further, the tribal position of two other genera is reconsidered. The monospecific Hololeius LaFerté-Sénectére, 1851 is redescribed and its current placement within Chlaeniini is confirmed, though it might be distantly related to the two new genera. Analysis of character states in species of Holosoma Semenov, 1889 leads me to transfer the genus from Oodini to Chlaeniini. Pictures of the taxa dealt with here are provided, including habitus, external characters, and genitalia. In addition, all the genera of the Oodini from the Oriental Region, including genera of Oriental Chlaeniini with oodine facies, are keyed for the first time.

A new oak-feeding species of Lachnus Burmeister and some remarks on the taxonomic status of L. chosoni Szelegiewicz (Hemiptera, Aphididae, Lachninae) https://dez.pensoft.net/article/1130/ Deutsche Entomologische Zeitschrift 61(1): 77-83

DOI: 10.3897/dez.61.7746

Authors: Mariusz Kanturski, Karina Wieczorek, Łukasz Junkiert

Abstract: A new species, Lachnus pseudonudus Kanturski & Wieczorek, sp. n., associated with Quercus ithaburensis subsp. macrolepis is described and figured in detail from specimens collected in Turkey. The lectotype and paralectotypes of L. crassicornis, a species associated with Quercus ithaburensis subsp. ithaburensis, are designated. The taxonomic position of L. chosoni, a poorly known species from Korea previously treated as a synonym of L. pallipes, is discussed. Morphological and biometric characters of the studied species are given. An identification key to species belonging to the “pallipes” group is provided.

Taxonomic revision of the cryptic ant genus Probolomyrmex Mayr (Hymenoptera, Formicidae, Proceratiinae) in Madagascar https://dez.pensoft.net/article/1129/ Deutsche Entomologische Zeitschrift 61(1): 65-76

DOI: 10.3897/dez.61.7634

Authors: Francisco Hita Garcia, Brian Fisher

Abstract: The alpha taxonomy of the ant genus Probolomyrmex in Madagascar is revised on the basis of the worker caste. Two new species are described: P. curculiformis sp. n. and P. zahamena sp. n. and the previously known P. tani is re-described. All three species are members of the P. greavesi species group. The species descriptions include diagnoses, taxonomic discussions, high quality montage images, and distribution maps. In addition, we provide an illustrated species level identification key.

A review of the genus Oosternum Sharp of the West Indies (Coleoptera: Hydrophilidae: Sphaeridiinae) https://dez.pensoft.net/article/1128/ Deutsche Entomologische Zeitschrift 61(1): 43-63

DOI: 10.3897/dez.61.7566

Authors: Albert Deler-Hernández, Franklyn Cala-Riquelme, Martin Fikácek

Abstract: The representatives of the genus Oosternum Sharp, 1882 occurring in the West Indies are revised. Ten species are recorded, of which seven are here described as new: Oosternum andersoni sp. n. (Cuba), O. bacharenge sp. n. (Dominican Republic), O. cercyonoides sp. n. (Jamaica), O. insulare sp. n. (Jamaica), O. luciae sp. n. (Saint Lucia), O. megnai sp. n. (Cuba) and O. pecki sp. n. (Dominican Republic). Diagnoses and detailed distributional data are also provided for O. sharpi Hansen, 1999 (widespread throughout both Greater and Lesser Antilles), O. latum Fikáček, Hebauer & Hansen, 2009 (endemic to St. Vincent) and an undescribed species from the Bahamas. A key to the West Indian Oosternum is provided and important diagnostic characters are illustrated. The West Indian fauna of Oosternum contains representatives of five different species groups and likely originated by multiple independent colonizations from the American continent. Within the study region, the highest diversity is known from the Greater Antilles, where two endemic species each in Cuba, Jamaica, and Hispaniola. The populations of O. sharpi were found to consist exclusively of females on all islands with the exception Puerto Rico.

Description of hitherto unknown fundatrices of Stomaphis graffii and S. longirostris (Hemiptera, Aphididae, Lachninae) https://dez.pensoft.net/article/1127/ Deutsche Entomologische Zeitschrift 61(1): 31-36

DOI: 10.3897/dez.61.7185

Authors: Łukasz Depa, Mariusz Kanturski

Abstract: The hitherto unknown fundatrices of two large aphid species having a cryptic mode of life, Stomaphis graffii Cholodkovsky, 1894 and S. longirostris (Fabricius, 1787), are described from specimens collected in Poland. Key to identification of known fundatrices of European representatives of the genus Stomaphis is provided and the observed morphological features are discussed.

Revision of the flat bug family Aradidae from Baltic Amber IX. Aradus macrosomus sp. n. (Hemiptera: Heteroptera) https://dez.pensoft.net/article/1124/ Deutsche Entomologische Zeitschrift 61(1): 27-29

DOI: 10.3897/dez.61.7155

Authors: Ernst Heiss

Abstract: The present paper is a continuation of previous contributions describing fossil Aradus species from Baltic Amber inclusions (Heiss 1998, 2002, 2013). Aradus macrosomus sp. n. is a well- preserved large new species which is described and illustrated herein. It differs by a combination of characters from the known Eocene and extant Aradus taxa, documenting again the unexpected richness of species diversity preserved in Baltic Amber.
