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.

DOI: 10.3897/dez.71.112278

Authors: Fang-Shuo Hu, Emmanuel Arriaga-Varela, Gabriel Biffi, Ladislav Bocák, Petr Bulirsch, Albert František Damaška, Johannes Frisch, Jiří Hájek, Peter Hlaváč, Bin-Hong Ho, Yu-Hsiang Ho, Yun Hsiao, Josef Jelínek, Jan Klimaszewski, Robin Kundrata, Ivan Löbl, György Makranczy, Keita Matsumoto, Guan-Jie Phang, Enrico Ruzzier, Michael Schülke, Zdeněk Švec, Dmitry Telnov, Wei-Zhe Tseng, Lan-Wei Yeh, My-Hanh Le, Martin Fikáček

Abstract: We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 species of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculionidae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylinidae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylonidae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive.

Two new species of Deuterophlebia Edwards, 1922 from Southwestern China (Diptera, Deuterophlebiidae) https://dez.pensoft.net/article/108096/ Deutsche Entomologische Zeitschrift 70(2): 387-401

DOI: 10.3897/dez.70.108096

Authors: Xuhongyi Zheng, Changfa Zhou

Abstract: The family Deuterophlebiidae is considered the most plesiomorphic Diptera family, with striking morphology and life history. In this study, we provide detailed descriptions and figures of two new species from Southwestern China: Deuterophlebia pseudopoda sp. nov. and Deuterophlebia pachychaeta sp. nov., along with genetic distances of COI sequences between the seven known Chinese species of Deuterophlebia Edwards, 1922. The two new species can be identified by the adults’ male terminalia, head structures, male and female antennae and mesothoracic spines or abdominal projections of the pupae. As a result, China is currently the country with the highest Deuterophlebia species diversity.

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.

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 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.

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.

A remarkable new genus of Nevrorthidae (Neuroptera, Osmyloidea) from mid-Cretaceous Kachin amber of northern Myanmar https://dez.pensoft.net/article/98873/ Deutsche Entomologische Zeitschrift 70(1): 113-120

DOI: 10.3897/dez.70.98873

Authors: Hiroshi Nakamine, Shûhei Yamamoto, Yui Takahashi, Xingyue Liu

Abstract: A remarkable new genus and species of Nevrorthidae, Sisyroneurorthus aspoeckorum gen. et sp. nov., is described from mid-Cretaceous Kachin amber of northern Myanmar. This new species is the second Mesozoic representative of Nevrorthidae. The distal fusion of ScP and RA in the forewing of this new genus is shared by most Sisyridae. Given the probable sister-group relationship between Nevrorthidae and Sisyridae, our study sheds light on the evolution and morphological diversity of Nevrorthidae in the Mesozoic era.

First nymph-imago association in Polyploica confirming the distribution of Euthyplociidae (Ephemeroptera) in China https://dez.pensoft.net/article/96986/ Deutsche Entomologische Zeitschrift 70(1): 1-11

DOI: 10.3897/dez.70.96986

Authors: Xuhongyi Zheng, Xinhe Qiang, Changfa Zhou

Abstract: In this study, the imagoes and subimagoes of Polyplocia orientalis Nguyen & Bae, 2003 (Ephemeroptera, Euthyplociidae) were reared from nymphs in the lab and described for the first time. Nymphal structures are also photographed and described. The imagoes of this species can be identified by having transparent wings (except costal and subcostal areas), sterna without regular markings and penis divergent in apical half and basal half fused. The K2P distance between newly-sequenced COI gene of Chinese materials and a stored Vietnamese one is 0.10. This report not only confirms the presence of the genus and family in China, but also provides the first nymph-imago association in the genus.

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.

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).

Six previously described species — P. brunneus Karsch, P. insignitus Bedel, P. languidus Reiche & Saulcy, P. ledouxi Morvan, P. taghizadehi Morvan, and P. weiratheri Mařan — are redescribed based on type and/or non-type material. P. davatchii Morvan placed as a member of the subgenus was not treated due to the lack of material available for study. The following new nomenclature acts are proposed: Platyderus brunneus Karsch, 1881, stat. rev., is removed from synonymy with Feronia languida Reiche & Saulcy, 1855; Platyderus elegans Bedel, 1900, syn. nov., is proposed as junior synonym of Platyderus brunneus Karsch, 1881; Platyderus ferrantei Reitter, 1909 is proposed as subspecies Platyderus brunneus ferrantei Reitter, 1909, stat. nov. In order to preserve the stability of nomenclature, lectotypes are designated for: Feronia languida Reiche & Saulcy, Platyderus brunneus Karsch, and Platyderus weiratheri Mařan. Keys to identification of the male and female specimens of the species from the regions studied are provided.

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.

First instar nymphs of two peltoperlid stoneflies (Insecta, Plecoptera, Peltoperlidae) https://dez.pensoft.net/article/65540/ Deutsche Entomologische Zeitschrift 68(1): 179-188

DOI: 10.3897/dez.68.65540

Authors: Shodo Mtow, Tadaaki Tsutsumi

Abstract: The first instar nymphs of two peltoperlid stoneflies, i.e., Microperla brevicauda Kawai, 1958 of Microperlinae and Yoraperla uenoi (Kohno, 1946) of Peltoperlinae, were examined and described. Additionally, the phylogeny and groundplan of the first instar nymphs of Peltoperlidae and Plecoptera were considered. The first instar nymphs of M. brevicauda have a slender body with a prognathous head of typical shape; they represent a groundplan in Plecoptera. On the other hand, the first instar nymphs of Y. uenoi have a broad, cockroach-like body with an orthognathous and shortened head, the latter being regarded as a potential autapomorphy of Peltoperlinae. Such differences in body shape between the subfamilies are speculated to arise from heterochrony. The three-segmented cerci of Y. uenoi are characteristic to Systellognatha, whereas the four-segmented cerci of M. brevicauda were independently acquired within Microperlinae. The structure and distribution pattern of chloride cells in the first instar nymphs of Plecoptera were also discussed. The presence of coniform chloride cells is a potential groundplan of Arctoperlaria. One to two pairs of chloride cells are distributed on the first nine abdominal segments of M. brevicauda; this represents a groundplan character of Systellognatha. On the other hand, one to four pairs of chloride cells are found on the second to ninth abdominal segments of Y. uenoi; this distribution pattern may be an apomorphic groundplan of Peltoperlinae.

Records and descriptions of caddisflies from Natma Taung National Park and adjacent localities in the Chin Hills of Myanmar (Insecta, Trichoptera) https://dez.pensoft.net/article/61819/ Deutsche Entomologische Zeitschrift 68(1): 139-164

DOI: 10.3897/dez.68.61819

Authors: Wolfram Mey, Hans Malicky

Abstract: During several excursions to the Chin Hills of Myanmar from 2001 to 2015, rich collections of caddisflies were made which form the basis of the present taxonomic and biogeographic study. A total of 106 species were identified including seven new species. They are described as Arctopsyche subflava sp. nov., Hydromanicus abdominalis sp. nov., Cheumatopsyche janosolahi sp. nov., Lepidostoma subpanaitos sp. nov., Aplatyphylax pumilus sp. nov., Adicella natmataungensis sp. nov. and Triaenodes mindatensis sp. nov. Illustrations of the male genitalia and images of the adults are provided. Two species names were recognised as junior synonyms: Hydropsyche athamas Malicky & Chantaramongkol, 2000, = Hydropsyche januha Oláh & Barnard, 2008, syn. nov.; Hydropsyche khasigiri Oláh & Barnard, 2008, = Hydropsyche kiogupa Oláh & Schefter, 2008, syn. nov. In an attempt to determine the biogeographic character of the fauna, the known ranges of all resident species were plotted into three longitudinal transects from 85°–95°E, 95–98°E and 98°–108°E, ranging from the eastern Himalayas to northern Vietnam. About half of the species have ranges extending over all three transects. The fauna is equally composed of western and eastern species qualifying the Chin Hills as part of a transition zone including palearctic elements. Most of the species, which are widely distributed in south-east Asia, are members of the suborder Annulipalpia. The investigations of the authors yielded 77 autochthonous species, which have been unrecorded from the country including the newly-described taxa. This brings the number of species records from Mynamar to 304.

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.

Revision of the Plagiolepis schmitzii group with description of Pl. invadens sp. nov. – a new invasive supercolonial species (Hymenoptera: Formicidae) https://dez.pensoft.net/article/53199/ Deutsche Entomologische Zeitschrift 67(2): 183-196

DOI: 10.3897/dez.67.53199

Authors: Bernhard Seifert

Abstract: Using high-resolution stereomicroscopy and exploratory data analyses, a taxonomic revision of the cryptic species close to Plagiolepis schmitzii Forel, 1895, called Pl. schmitzii group, was conducted. Morphology was numerically recorded under highly standardised conditions considering absolute size and 16 shape, pubescence and surface characters. A key to the non-parasitic Westpalaearctic species of the ant genus Plagiolepis Mayr, 1861 is provided which firstly separates, on species group level, the Pl. pygmaea (Latreille) species group, the Pl. pallescens Forel species group and the Pl. schmitzii species group and, finally, on species level, the cryptic species of the latter group. The recognised species of the Pl. schmitzii species group are Pl. schmitzii Forel, 1895 (invasive species), Pl. barbara Santschi, 1911, Pl. atlantis Santschi, 1920 and Pl. invadens sp. nov. (invasive species) that is described as new from a supercolony in Germany. Based on morphological arguments, the taxa Pl. barbara var. madeirensis Emery, 1921, Pl. maura polygyna Santschi, 1922 and Pl. schmitzii var. tingitana Santschi, 1936 are recognised as junior synonyms of Pl. schmitzii, the taxa Pl. schmitzii crosi Santschi, 1920, Pl. pallescens var. kabyla Santschi, 1920 and Pl. perperamus Salata et al., 2018 as junior synonyms of Pl. atlantis and the taxon Pl. maura Santschi, 1920 as junior synonym of Pl. barbara. A concluding comparative section suggests that pre-adaptations for anthropogenous dispersal and transformation to supercoloniality in introduction areas are apparently common traits in Plagiolepis ants.

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.

Contribution to the knowledge of male and female eremochaetid flies in the late Cretaceous amber of Burma (Diptera, Brachycera, Eremochaetidae) https://dez.pensoft.net/article/33914/ Deutsche Entomologische Zeitschrift 66(1): 75-83

DOI: 10.3897/dez.66.33914

Authors: Qingqing Zhang, Junfeng Zhang

Abstract: A new and a previously known species of the genus Zhenia Q. Zhang, 2016 (Eremochaetidae) are illustrated and described based on two males and a female in amber: Zhenia burmensis sp. nov. and Z. xiai Q. Zhang, 2016. The male Z. xiai is the first male of this species recorded. The relationships of Archisargoidea (including Eremochaetidae, Zhenia) are reassessed based on male genitalia. The superfamily is more likely related to the Stratiomyomorpha than to the Muscomorpha (including Nemestrinoidea). The components and structures of the ovipositor are re-illustrated. The results of our comparative study demonstrate that the ovipositor of Zhenia is similar in shape and detail to that of Rhagoletis pomonella (Walsh, 1867) (Tephritidae). This study concludes that the ovipositor of Zhenia is most likely formed from abdominal eighth and ninth segments instead of the cerci, as a previous study found.

Revision of the Quedius fauna of Middle Asia (Coleoptera, Staphylinidae, Staphylininae) https://dez.pensoft.net/article/27033/ Deutsche Entomologische Zeitschrift 65(2): 117-159

DOI: 10.3897/dez.65.27033

Authors: Maria Salnitska, Alexey Solodovnikov

Abstract: Twenty eight species of the genus Quedius from Middle Asia comprising Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, are revised. Quedius altaicus Korge, 1962, Q. capitalis Eppelsheim, 1892, Q. fusicornis Luze, 1904, Q. solskyi Luze, 1904 and Q. cohaesus Eppelsheim, 1888 are redescribed. The following new synonymies are established: Q. solskyi Luze, 1904 = Q. asiaticus Bernhauer, 1918, syn. n.; Q. cohaesus Eppelsheim, 1888 = Q. turkmenicus Coiffait, 1969, syn. n., = Q. afghanicus Coiffait, 1977, syn. n.; Q. hauseri Bernhauer, 1918 = Q. peneckei Bernhauer, 1918, syn. n., = Q. ouzbekiscus Coiffait, 1969, syn. n.; Q. imitator Luze, 1904 = Q. tschinganensis Coiffait, 1969, syn. n.; Q. novus Eppelsheim, 1892 = Q. dzambulensis Coiffait, 1967, syn. n., Q. pseudonigriceps Reitter, 1909 = Q. kirklarensis Korge, 1971, syn. n. Lectotypes are designated for Q. asiaticus Bernhauer, 1918, Q. fusicornis Luze, 1904, Q. hauseri Bernhauer, 1918, Q. imitator Luze, 1904, Q. novus Eppelsheim, 1892 and Q. solskyi Luze, 1904. For all revised species, taxonomy, distribution and bionomics are summarized. Quedius fuliginosus (Gravenhorst, 1802), Q. sundukovi Smetana, 2003 and Q. pseudonigriceps Reitter, 1909 are recorded for Middle Asia for the first time. One species from the Q. coloratus-group, found to be new to science is not described due to shortage of material. Another possibly new species is tentatively identified as Q. fulvicollis Stephens, 1833 until the taxonomy of that widespread species is revised. An identification key to all species is provided.

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.

Abstract: The revised checklist of the subtribe Poliina Hampson, 1902 is presented; one new genus, Multisignagen. n., three new subgenera (Atropolia, Leuconephropolia and Protopoliasubgen. n.) and a new species (Polia (Atropolia) posterodilutasp. n.) are described. The taxonomic position of the recently described subgenus Metallopolia is discussed. The subtribe Pachetrina Beck, 1996 is synonymised with Poliina; two genera (Kollariana Hacker, 1996 and Spiramater McCabe, 1980) are transferred to the subtribe Mamestrina Hampson, 1902. A number of lectotype designations and new combinations are given; the newly designated lectotypes and the genitalia of the disputed taxa are illustrated.

New findings of Flagellisargus J Zhang, 2012 (Diptera, Brachycera, Archisargidae), with discussion of the placements of some controversial taxa https://dez.pensoft.net/article/13550/ Deutsche Entomologische Zeitschrift 64(2): 111-122

DOI: 10.3897/dez.64.13550

Authors: Junfeng Zhang

Abstract: A new species of a new subgenus and a similar known species referred to the genus Flagellisargus J Zhang, 2012 are described and illustrated based on a male and a female impression fossils of these flies: Flagellisargus (Changbingisargus) parvussubgen. et sp. n. and Flagellisargus (Flagellisargus) cf. sinicus J Zhang, 2012. The latter taxon is the first record of a female Flagellisargus. Recently taken out of Archisargoidea, this study concludes that Flagellisargus should be an archisargid genus based on the known (male) and new (female) impression fossils. The placement of Daohugosargus J Zhang, 2012b is reassessed. It demonstrates close similarities in body structure and wing venation to archisargid flies, and can be retained as an archisargid genus. Archirhagio mostovskii J Zhang, 2015 is separated from Archirhagio zhangi K Zhang et al., 2009. Helempis Ren, 1998 could be, as a separate genus, placed in Archisarginae, Archisargidae.

Pseudochrysis Semenov, 1891 is the valid genus name for a group of cuckoo wasps frequently referred to as Pseudospinolia Linsenmaier, 1951 (Hymenoptera, Chrysididae) https://dez.pensoft.net/article/13005/ Deutsche Entomologische Zeitschrift 64(1): 69-75

DOI: 10.3897/dez.64.13005

Authors: Paolo Rosa, Maurizio Pavesi, Villu Soon, Oliver Niehuis

Abstract: The cuckoo wasp genus Pseudochrysis Semenov, 1891 is currently treated by several authors as a junior subjective synonym of Euchroeus Latreille, 1809, due to a type species designation by O. W. Richards in 1935. In the original description of the genus Pseudochrysis, Semenov (1891) distinguished two subordinated taxa within the genus Pseudochrysis: the subgenus Pseudochrysis and the subgenus Spintharis (sensu Dahlbom 1854). Semenov included three species in the subgenus Spintharis, but failed to mention any species included in the nominal subgenus. He was the first author, however, who listed in a subsequent publication (Semenov 1892) eleven species to be included in the nominal subgenus. According to the International Code of Zoological Nomenclature (ICZN 1999, Art. 67.2.2), these eleven species are deemed to have been listed in the original description. One of these, Chrysura humboldti Dahlbom, 1845, was explicitly designated by Semenov (1892) as type species of Pseudochrysis. We therefore consider the designation of Pseudochrysis (Spintharis) virgo Semenov, 1891 as type species of Pseudochrysis by Richards (1935) as invalid. The currently widely used genus name Pseudospinolia Linsenmaier, 1951 (type species Chrysis uniformis Dahlbom, 1854) is consequently to be regarded as a junior subjective synonym of Pseudochrysis, given the current circumscription of the genus Pseudospinolia (including both Pseudospinolia humboldti and Pseudospinolia uniformis).

On the enigmatic Sinonemestrius Hong & Wang, 1990, with description of a new species based on a complete fossil fly (Diptera, Brachycera, Tabanomorpha, Heterostomidae) https://dez.pensoft.net/article/11724/ Deutsche Entomologische Zeitschrift 64(1): 61-67

DOI: 10.3897/dez.64.11724

Authors: Junfeng Zhang

Abstract: A new species of Sinonemestrius Hong & Wang, 1990 is described and illustrated based on a complete compression fossil of the fly. Currently placed in Rhagionemestriidae or Xylophagidae, the present study concludes that the morphology of the new find indicates that Sinonemestrius is a heterostomid genus within Tabanomorpha. The placement of Ahirmoneura neimengguensis K-y Zhang et al., 2008 is reassessed. It demonstrates close similarities in body structure and wing venation to those of Sinonemestrius, and can be provisionally transferred from Nemestrinidae to Heterostomidae: Sinonemestriinae.

Taxonomy and phylogeny of the genera Gymnocnemia Schneider, 1845, and Megistopus Rambur, 1842, with remarks on the systematization of the tribe Nemoleontini (Neuroptera, Myrmeleontidae) https://dez.pensoft.net/article/11704/ Deutsche Entomologische Zeitschrift 64(1): 43-60

DOI: 10.3897/dez.64.11704

Authors: Davide Badano, Horst Aspöck, Ulrike Aspöck

Abstract: The delineation of antlion genera has often been based on morphological characters not tested in a phylogenetic context, thus seriously impairing the study of systematics of the family Myrmeleontidae. Nebulous generic limits also impede the taxonomy and study of the affinities of closely related species. As a case study, the generic placement of Megistopus mirabilis Hölzel, 1980, was based on a single leg character. To test the position of this species, the reciprocal relationships of the members of the genera Gymnocnemia Schneider, 1845, and Megistopus Rambur, 1842 were investigated, using a morphology-based phylogenetic analysis. This approach demonstrated that M. mirabilis should actually be assigned to the genus Gymnocnemia, as G. mirabilis comb. n. This analysis also supports the subdivision of the tribe Nemoleontini in two subclades based on morphology of male and female genitalia. A new characterisation of these genera is provided, as well as a redescription of the very rare G. mirabilis and the poorly investigated Megistopus lucasi (Navás, 1912). An updated identification key to the members of the genera Gymnocnemia and Megistopus is presented.

Review of the world species of Exoryza (Hymenoptera, Braconidae, Microgastrinae), with description of five new species https://dez.pensoft.net/article/8977/ Deutsche Entomologische Zeitschrift 63(2): 195-210

DOI: 10.3897/dez.63.8977

Authors: Jose L. Fernandez-Triana, James B. Whitfield, M. Alex Smith, Tanya Dapkey, Winnie Hallwachs, Daniel H. Janzen

Abstract: The world species of the genus Exoryza (Hymenoptera, Braconidae, Microgastrinae) are revised. Ten species are recognized, including five new, authored by Fernandez-Triana: mariabustosae, richardashleyi, ritaashleyae, rosamatarritae and yeimycedenoae. The species Dolichogenidea oryzae Walker, 1994 is considered as related to Exoryza – although is not formally transferred to that genus. A dichotomous key to all species, descriptions and illustrations are provided. The only region where the genus is not yet recorded is Australasia, but this may be a collecting artifact. Host caterpillars (Lepidoptera) include species within Choreutidae, Depressariidae, Gelechiidae, and Pyraloidea – all but Pyraloidea are new host records. The status of Exoryza is questioned (it may only represent a species-group within the genus Dolichogenidea) but it is retained as a valid genus until a comprehensive phylogenetic study of Microgastrinae is available.

Workers, soldiers, and gynes – morphometric characterization and description of the female castes of Camponotus singularis (Smith, 1858) (Hymenoptera, Formicidae) https://dez.pensoft.net/article/9435/ Deutsche Entomologische Zeitschrift 63(2): 183-193

DOI: 10.3897/dez.63.9435

Authors: Alice Laciny, Herbert Zettel, Irina Druzhinina

Abstract: Species of Camponotus Mayr, 1861 show a high variation of worker caste numbers, from a monomorphic worker caste to strong polymorphism along a continuous range of worker sizes or true worker dimorphism. Camponotus singularis (Smith, 1858) is used as a model for a Camponotus species with two very distinct worker castes (minors and majors) which are chiefly defined by morphometric data. We investigated shifts in proportions of C. singularis female castes in order to identify major allometric patters useful for characterizing caste differences in this species as well as in other Camponotini. We describe the main morphological traits which are characteristic for the respective morphs. The major worker, or “soldier”, shows many characteristics which deviate from the minor worker, but also from the alate gyne. Its traits are assumingly modified for its function in nest defence. Morphometric data clearly set Bornean specimens of Camponotus singularis (described as var. rufomaculatus Donisthorpe, 1941) apart from specimens with other proveniences, suggesting that this island population is a distinct species.

Abstract: Burnilia japonica sp. n. of the delphacid subfamily Plesiodelphacinae from southern Japan (Kyushu, Yakushima, Okinawa) is described. The surprising discovery of a Burnilia-species in Japan is the first record of a member of this subfamily outside the New World. As the generic assignment is beyond any doubts, this finding reveals a puzzling geographic distribution of this group. A natural – indigenous – occurrence of B. japonica in Japan versus a recent introduction e.g., by human traffic, is discussed. A phylogenetic study of the whole Plesiodelphacinae including the Japanese species is desired.

DOI: 10.3897/dez.63.5885

Authors: Sayeh Serri, Johannes Frisch

Abstract: The species diversity, chorology, and biogeography of the Steninae MacLeay, 1825 (Coleoptera: Staphylinidae) in Iran is described. A total of 68 species of Stenus Latreille, 1797 and one species of Dianous Leach, 1819 is recorded for this Middle Eastern country. Dianous coerulescens korgei Puthz, 2002, Stenus bicornis Puthz, 1972, S. butrintensis Smetana, 1959, S. cicindeloides Schaller, 1783, S. comma comma Le Conte, 1863, and S. hospes Erichson, 1840 are recorded for the Iranian fauna for the first time. Records of S. cordatoides Puthz, 1972, S. guttula P. Müller 1821, S. melanarius melanarius Stephens, 1833, S. planifrons planifrons Rey, 1884, S. pusillus Stephens, 1833, and S. umbricus Baudi di Selve, 1870 for Iran are, however, implausible or proved erroneous. Based on literature records and recent collecting data since 2004, the distribution of the stenine species in Iran is mapped, and their biogeographical relationships are discussed. As far as possible, the species are attributed to the commonly accepted distribution types in the Palaearctic Region after the theory of Pleistocene refuges of the arboreal biota. With the example of the Steninae and Scopaeus Erichson, 1839 (Staphylinidae: Paederinae), a cluster analysis is performed to examine the similarity of commonly accepted geographical units of Iran. The similar biogeographic pattern of the Steninae and Scopaeus reveal the high impact of Mediterranean elements on the fauna of Iran. The Hyrcanian subregion of the Caspian refuge is identified as the most significant center of origin of Stenus in Iran.

Abstract: Idris Förster is a megagenus in the tribe Baeini comprising species that exclusively parasitize the eggs of spiders dwelling in vegetation and leaf litter. This is the only tribe in Platygastridae capable of using spider eggs for their development. Constructing species groups will facilitate studies of highly speciose genera like Idris. So far only one species group ‘the melleus-group’ has been proposed in this genus. A new species group ‘the adikeshavus-group’ from India is proposed. Five new species in this genus – I. adikeshavus, I. deergakombus, I. brevicornis, I. lopamudra and I. teestai – are described from India. All five species are imaged and a key to them is provided.

(type locality: China, SE Guizhou Province, Leishan County, SE Kaili) and Apophylon pangu Guéorguiev & Sciaky, sp. n. (type locality: China, NW Hunan Province, Wulingyuan District, near the town of Wulingyuan). These two species share a unique combination of characters, not known in any other Pterostichini. The new genus can be distinguished by having (1) a left paramere without transverse apophysis; (2) a falcate right paramere, with styloid apex, broadened medial part and subbasal hasp; (3) a median lobe with dorsal ostium; (4) metatarsomeres 1-2 setose on the medioventral surface, in addition to the lateroventral setae; (5) meso- and metatarsomeres 1–4 with two dorsolateral grooves diverging distally; and (6) elytral striae with shining isodiametric microreticulation, which is in contrast to less shining transverse-mesh microreticulation on the elytral intervals.

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.

New species and new combinations of Asian Batrisodes Reitter (Coleoptera, Staphylinidae, Pselaphinae), and synonymy of Batrisodellus Jeannel with Batrisodes https://dez.pensoft.net/article/4539/ Deutsche Entomologische Zeitschrift 62(1): 45-54

DOI: 10.3897/dez.62.4539

Authors: Zi-Wei Yin, Jia-Wei Shen, Li-Zhen Li

Abstract: Continuing surveys on the pselaphine fauna in China have revealed four undescribed species of the genus Batrisodes: Batrisodes angustelytratus sp. n. (with Pachycondyla ant) and B. longwangshanus sp. n. from Zhejiang, B. bamian sp. n. (with Pseudolasius ant) from Hunan, and B. songxiaobini sp. n. (with Formica ant) from Yunnan. The genus Batrisodellus is placed as a junior synonym of Batrisodes, syn. n.; this taxonomic act results in eight new combinations: Batrisodes cerberus, B. coprea, B. cristatus, B. fengtingae, B. laticollis, B. longulus, B. palpalis, and B. punctipennis. The Russian Far East species Basitrodes cornutus is transferred to Batrisodes, comb. n.

Systematic position of Eulachnus cembrae Börner with description of hitherto unknown sexual morphs of E. pumilae Inouye (Hemiptera, Aphididae, Lachninae) https://dez.pensoft.net/article/4196/ Deutsche Entomologische Zeitschrift 61(2): 123-132

DOI: 10.3897/dez.61.8048

Authors: Mariusz Kanturski, Karina Wieczorek

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.

A taxonomic revision of Parallelodemas Faust from South China (Coleoptera, Curculionidae, Baridinae), with notes on sexually dimorphic characters https://dez.pensoft.net/article/4077/ Deutsche Entomologische Zeitschrift 61(2): 105-119

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.

Caddisflies (Trichoptera) from Lombok, Bali and Java (Indonesia), with a discussion of Wallace’s Line https://dez.pensoft.net/article/1119/ Deutsche Entomologische Zeitschrift 61(1): 3-14

DOI: 10.3897/dez.61.7046

Authors: Hans Malicky, Vladimir Ivanov, Stanislav Melnitsky

Abstract: Caddisflies (Trichoptera) of Southeast Asia are analyzed with special attention to the Sunda Islands to evaluate the zoogeographic effects of island isolation and potential influence from the neighboring continental faunas. Results of recent Trichoptera collections and synopsis of previously published data for the islands of Java, Bali, and Lombok are presented along with their zoogeographical interpretation on the islands as well as on the adjacent regions. A total of 202 Trichoptera species is known to occur on the three islands; 146 species are known in Java, 73 in Bali and 61 in Lombok. 43 species are common to Java and Bali, 27 to Java and Lombok, 30 to Bali and Lombok, 70 to Java and Sumatra. A significant decrease in species richness has been observed in comparison to the Asian mainland. The caddisfly fauna of the three islands is of Asiatic origin, no Australian influence was noted. The well-known Wallace’s line does not act as a faunistic border between Bali and Lombok for Trichoptera.
