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.

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.

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.

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.

Recent additions to the list of German sawflies (Hymenoptera, Symphyta) https://dez.pensoft.net/article/54002/ Deutsche Entomologische Zeitschrift 67(2): 127-139

DOI: 10.3897/dez.67.54002

Authors: Andrew Liston, Marko Prous

Abstract: Two tenthredinid sawfly species are newly recorded in Germany: Pristiphora krausi (Lacourt, 2006) and P. melagonia sp. nov. The latter is also recorded from Greece and Spain. These species belong to the Pristiphora depressa group, as confirmed by genetic data. Additional data are presented for seven other tenthredinid species which have only rarely been recorded in Germany and for which previously-published data are incomplete. Identification keys to the West Palaearctic species of Eurhadinoceraea and the Pristiphora depressa group are included. Other species of Symphyta, first recorded in Germany since the publication of the most recent checklist, are listed in a table, with references to literature which describes identification characters.

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.

A revolutionary protocol to describe understudied hyperdiverse taxa and overcome the taxonomic impediment https://dez.pensoft.net/article/34683/ Deutsche Entomologische Zeitschrift 66(2): 119-145

DOI: 10.3897/dez.66.34683

Authors: Sarah Meierotto, Michael J. Sharkey, Daniel H. Janzen, Winnie Hallwachs, Paul D. N. Hebert, Eric G. Chapman, M. Alex Smith

Abstract: Here we elucidate and justify a DNA barcode approach to insect species description that can be applied to name tens of thousands of species of Ichneumonoidea and many other species-rich taxa. Each description consists of a lateral habitus image of the specimen, a COI barcode diagnosis, and the holotype specimen information required by the International Code of Zoological Nomenclature. We believe this approach, or a slight modification of it, will be useful for many other underdescribed hyperdiverse taxa, especially in the tropics. Due to the extreme species-richness of the Ichneumonoidea, the very low percentage of described species, and the lack of detailed biological information for most described species, the standard taxonomic approach is inefficient and overwhelmingly time consuming. A DNA barcode-based approach to initial description will provide a solid foundation of species hypotheses from which more comprehensive descriptions can be developed as other data, time, and budgets permit. Here we elucidate this view and detailed methodology that can generally be applied to species-rich underdescribed taxa. A real example is given by describing species in two genera, Hemichoma and Zelomorpha, reared from the Área de Conservación Guanacaste in northwestern Costa Rica. The generic type species Zelomorpha arizonensis is given a DNA barcode diagnosis and the following new species are described: Zelomorpha angelsolisi, Zelomorpha bobandersoni, Zelomorpha danjohnsoni, Zelomorpha donwindsori, Zelomorpha effugia, Zelomorpha johnchemsaki, Zelomorpha kellyanneae, Zelomorpha larrykirkendalli, Zelomorpha mariyavladmirovnae, Zelomorpha mikeiviei, Zelomorpha myricagaleae, Zelomorpha noahjaneae, Zelomorpha paulgoldsteini, Zelomorpha terryerwini, Zelomorpha willsflowersi, Hemichoma donwhiteheadi, Hemichoma frankhovorei, and Hemichoma johnkingsolveri.

On Bulgarian sawflies, including a new species of Empria (Hymenoptera, Symphyta) https://dez.pensoft.net/article/34309/ Deutsche Entomologische Zeitschrift 66(1): 85-105

DOI: 10.3897/dez.66.34309

Authors: Andrew Liston, Marko Prous, Jan Macek

Abstract: Thirty-nine species of sawfly (Symphyta) are recorded for the first time in Bulgaria. Most of these were collected during early spring of 2018, in the south-east of the country (Burgas and Varna Provinces). Empria aridicola Macek & Prous, sp. nov. is described as new to science from specimens collected in several central, east and south European countries. Lectotypes are designated for Poecilosoma parvula Konow, 1892, Empria pravei Dovnar-Zapolskij, 1925 and E. pseudoklugi Dovnar-Zapolskij, 1929. Empria pravei and Sciapteryx byzantina Benson, 1968 are at present only known in Europe from the coastal zone of the Black Sea. The new Bulgarian records of Hoplocampa cantoti Chevin, 1986 and Neomessa steusloffi (Konow, 1892) represent large extensions in their recorded ranges, previously comprising respectively only northern France, and north-eastern Germany. Possible host plant associations are noted for several species, based on observations of adults.

Taxonomic review of Australian Mecyclothorax Sharp (Coleoptera, Carabidae, Moriomorphini) with special emphasis on the M. lophoides (Chaudoir) species complex https://dez.pensoft.net/article/27424/ Deutsche Entomologische Zeitschrift 65(2): 177-224

DOI: 10.3897/dez.65.27424

Authors: James K. Liebherr

Abstract: The Australian fauna of Mecyclothorax Sharp (Coleoptera: Carabidae: Moriomorphini) is reviewed, with special focus on species assigned to the monophyletic subgenus Eucyclothorax Liebherr: M. isolatus, sp. n. from Western Australia, M. moorei Baehr, M. punctatus (Sloane), M. curtus (Sloane), M. blackburni (Sloane); M. eyrensis (Blackburn); M. peryphoides (Blackburn); M. darlingtoni, sp. n. from Queensland; M. jameswalkeri, sp. n. from Western Australia; M. lophoides (Chaudoir); and M. cordicollis (Sloane). The last six species listed above–the M. lophoides species complex–have been the source of long-term confusion for taxonomists, with male genitalic characters providing trouble-free species circumscription. One new subspecies, M. lewisensis estriatus, subsp. n. from Queensland is added to the seven previously described taxa of the monophyletic subgenus Qecyclothorax Liebherr. The balance of the fauna consists of four species in the subgenus Mecyclothorax: 1 and 2, the sister-species pair M. lateralis (Castelnau) and M. minutus (Castelnau); 3, M. ambiguus (Erichson); and 4, M. punctipennis (MacLeay). Mecyclothorax fortis (Blackburn), syn. n., is newly synonymized with M. minutus. Mecyclothorax ovalis Sloane is recombined as Neonomius ovalis (Sloane), comb. n., and a neotype is designated to replace the destroyed holotype. Phylogenetic relationships for the Australian Mecyclothorax are proposed based on information from 68 terminal taxa and 139 morphological characters. The biogeographic history of Australian Mecyclothorax is deduced based the sister-group relationship between Mecyclothorax and the Amblytelus-related genera, with both groups hypothesized to have originated during the late Eocene. Diversification within Mecyclothorax has occurred since then in montane rainforests of tropical Queensland, temperate forest biomes of the southwest and southeast, and in grasslands and riparian habitats adjacent and inland from those forests. Several species presently occupy interior desert regions, though no sister species mutually occupy such climatically harsh habitats. The M. lophoides species complex exhibits profound male genitalic diversification within the context of conserved external anatomy. This disparity is investigated with regard to the functional interaction of the male internal sac flagellum and female spermathecal duct. Though limited association of flagellar and spermathecal duct configurations can be documented, several factors complicate proposing a general evolutionary mechanism for the observed data. These include: 1, the occurrence of derived, elongate spermathecal ducts in three species, two of which exhibit very long male flagella, whereas males of the third exhibit a very short flagellum; and 2, a highly derived and exaggerated male flagellar configuration shared across a sister-species pair even though the two species can be robustly diagnosed using external anatomical characters, other significant genitalic differences involving male parameral setation, and biogeographic allopatry associated with differential occupation of desert versus forest biomes.

Cladistic classification of Mecyclothorax Sharp (Coleoptera, Carabidae, Moriomorphini) and taxonomic revision of the New Caledonian subgenus Phacothorax Jeannel https://dez.pensoft.net/article/21000/ Deutsche Entomologische Zeitschrift 65(1): 1-63

DOI: 10.3897/dez.65.21000

Authors: James K. Liebherr

Abstract: The 15 species of Mecyclothorax Sharp precinctive to New Caledonia are revised and shown by cladistic analysis to comprise a monophyletic lineage, here treated as subgenus Phacothorax Jeannel. The New Caledonian species of subgenus Phacothorax include Mecyclothorax fleutiauxi (Jeannel), M. najtae Deuve, and 13 newly described species: M. jeanneli sp. n., M. laterobustus sp. n., M. laterorectus sp. n., M. laterosinuatus sp. n., M. laterovatulus sp. n., M. manautei sp. n., M. megalovatulus sp. n., M. octavius sp. n., M. paniensis sp. n., M. picdupinsensis sp. n., M. plurisetosus sp. n., and two jointly authored species; M. kanak Moore & Liebherr sp. n., and M. mouensis Moore & Liebherr sp. n.. subgenus Phacothorax is one of five subgenera recognized within genus Mecyclothorax based on cladistic analysis of 65 exemplar taxa utilizing information from 137 morphological characters. The four other monophyletic subgenera include the precinctive Australian Eucyclothorax subgen. n. (type species Mecyclothorax blackburni [Sloane]), the precinctive Queensland Qecyclothorax subgen. n. (type species Mecyclothorax storeyi Moore), the precinctive New Zealand Meonochilus Liebherr & Marris status n., and the geographically widespread and very diverse nominate subgenus, distributed from St. Paul and Amsterdam Islands, eastward across Australia and New Guinea, and in the Sundas, Timor Leste, Lord Howe and Norfolk Islands, New Zealand, and the Society and Hawaiian Islands. The biogeographic history of Mecyclothorax can be derived from the parsimony cladogram time-calibrated by times of origin of particular geographic areas inhabited by resident representative species. Based on sister-group status of subgenus Phacothorax and subgenus Mecyclothorax, and occupation of Lord Howe Island–an island originating no earlier than 6 Ma–by the earliest divergent lineage within subgenus Mecyclothorax, the ancestor of present-day Phacothorax spp. is hypothesized to have colonized New Caledonia 6 Ma, subsequent both to Cretaceous Gondwanan vicariance as well as any Oligocene submergence. Area relationships among the New Caledonian Phacothorax point to earliest diversification incorporating the northern massifs, and most recent diversification on the ultramafic volcanic substrates in the south of Grand Terre. Flight wing loss has played an important role in shaping the various island faunas, both in their morphology as well as their diversity. The retention of flight capability in only a few of the many hundred Mecyclothorax spp. is presented in light of how populations evolve from macropterous colonizing propagules to vestigially winged specialists. Interspecific differences in genitalic structures for the sister-species pair M. fleutiauxi + M. jeanneli are shown to involve functional complementarity of male and female structures. Extensive geographic variation of male genitalia is demonstrated for several New Caledonian Mecyclothorax spp. This variation deviates from the geographically uniform male genitalia exhibited by species in the hyperdiverse Mecyclothorax radiation of Haleakalā volcano, Maui, suggesting that extensive sympatry occurring among species in that diverse species swarm selects for stability within this mate recognition system. Conversely, lower levels of sympatry characterizing the depauperate New Caledonian radiation permit the presence of more extensive male genitalic variation, this variation not selected against due to the lower likelihood of interspecific mating mistakes.

Spotted males, uniform females and the lowest chromosome number in Tettigoniids recorded: Review of the genus Gonatoxia Karsch (Orthoptera, Phaneropterinae) https://dez.pensoft.net/article/10799/ Deutsche Entomologische Zeitschrift 63(2): 271-286

DOI: 10.3897/dez.63.10799

Authors: Claudia Hemp, Klaus-Gerhard Heller, Elzbieta Warchalowska-Sliwa, Andreas Hemp

Abstract: The genus Gonatoxia Karsch, which was synonymized with Dapanera Karsch by Massa (2015), is re-established. Data on habitat, biology, ecology, the acoustics and on chromosomes are provided as well as a key to the species. The male of G. immaculata Karsch and the female of G. maculata Karsch are described. G. furcata sp. n. from the Udzungwa Mountains of Tanzania and G. helleri sp. n. inhabiting coastal and lowland wet forest are newly described. All species have calling songs consisting of very short, resonant syllables, produced in species specific intervals, and with peak carrier frequencies between 13 and 24 kHz. In respect to chromosome numbers Gonatoxia species showed extreme differences (from 29 to 7) suggesting rapid evolutionary changes. G. helleri sp. n. so far is the tettigoniid species with the lowest number of chromosomes at present. Gonatoxia species may be used as bioindicators, their presence suggesting valuable habitats that are vanishing rapidly in East Africa.

Abstract: A new species of hygropetric water strider, Onychotrechus dooarsicus sp. n. is described from Buxa Tiger Reserve, Dooars, West Bengal, India. Representatives of the new species were collected from a stream with boulders and rocks splashed by water, with slow current, situated at an altitude of 630 m a.s.l. This is the seventh species of Onychotrechus confirmed for India. The new species is closely related with O. robustus Andersen, 1980 from northwestern India and O. jaechi Zettel & Tran, 2007 from Bhutan. An identification key to males of all species of Onychotrechus species is also provided.
