Wang Ji-ShenNew and little-known species of the genus Dicerapanorpa from northwestern Yunnan, China (Mecoptera: Panorpidae)Acta Entomologica Musei Nationalis Pragae 62(1): 1-13
Abstract: The genus Dicerapanorpa Zhong & Hua, 2013 previously comprised 20 known species that are endemic to central and southwestern China. Herein, I present new knowledge of this genus from northwestern Yunnan, including descriptions of four new species, Dicerapanorpa harmonia sp. nov., Dicerapanorpa huangguocongi sp. nov., Dicerapanorpa nakhi sp. nov., and Dicerapanorpa yangqichengi sp. nov. In addition, three little-known species, Dicerapanorpa tenuis Hu, Wang & Hua, 2019, Dicerapanorpa tjederi Carpenter, 1938, and Dicerapanorpa triclada (Qian & Zhou, 2001) are redescribed and illustrated based on new materials. An updated key to all known 24 species of Dicerapanorpa is provided, and a distributional map of Dicerapanorpa species from Yunnan is presented. The evolution and biology of Dicerapanorpa are briefly discussed.Published online: 12th April 2022
Bilton David T., Mlambo Musa C.A new Copelatus with small eyes from the Eastern Cape Wild Coast, South Africa (Coleoptera: Dytiscidae)Acta Entomologica Musei Nationalis Pragae 62(1): 15-21
Abstract: A new diving beetle, Copelatus mkambati sp. nov., is described from the Mkambati Nature Reserve in the Eastern Cape Province, South Africa. The new species is compared with other Afrotropical taxa with two elytral striae and no submarginal stria (the macellus species group of Copelatus Erichson, 1832). A combination of small eyes, rather weak pigmentation, flattened, subparallel habitus, relatively large head and collecting circumstances all suggest that the new species may be semisubterranean in lifestyle.Published online: 12th April 2022
Biffi Garbriel, Migliore Letizia J., Casari Sônia A.Morphology of the larvae and biology of the adults of Psilorrhynchus bifasciatus do not confirm previous hypotheses about systematics and feeding habits (Coleoptera: Cantharidae)Acta Entomologica Musei Nationalis Pragae 62(1): 23-34
Abstract: Psilorrhynchus bifasciatus (Blanchard, 1844) is broadly distributed through South America, but its biology, behaviour and life cycle are unknown. The most characteristic feature of the adults is slender rostrum, presumably associated to a specialised feeding habit. However, new observations of P. bifasciatus feeding on nectar in inflorescences of Matayba guianensis Aubl. (Sapindaceae) do not support such a hypothesis. Here, we describe and illustrate their early larval instars in details and compare them with the other Chauliognathini. The larvae are remarkably characterised especially by a long and thick pubescence, conspicuous roughness on the head and thoracic terga, and head with sharp lateral projections. These features are unique amongst the known Cantharidae larvae and do not confirm a previous hypothesis of close affinity between Psilorrhynchus Gemminger & Harold, 1869 and bromeliad-inhabiting Chauliognathini species.Published online: 23rd April 2022
Perissinotto RenzoReview of the genera Elaphinis and Parelaphinis (Coleoptera: Scarabaeidae: Cetoniinae) with description of three new species from South AfricaActa Entomologica Musei Nationalis Pragae 62(1): 35-55
Abstract: The cetoniine genera Elaphinis Burmeister, 1842 and Parelaphinis Marais & Holm, 1989 are reviewed in the light of substantial new material that has become available recently. A new species, E. matatiele sp. nov., in the previously monotypic subgenus Elaphinis s. str. and closely related to E. (E.) cinereonebulosa (De Geer, 1778), is described from the southern Drakensberg area near Matatiele (Eastern Cape, South Africa). Within Parelaphinis, two new species, P. umtamvuna sp. nov. and P. drakensbergica sp. nov. are described and compared with P. moesta (Gory & Percheron, 1833) – hitherto the only member of the genus. The former is a mid- to lowland dweller, currently known only from the KwaZulu-Natal side of the Umtamvuna River valley (South Africa). The latter is a montane species apparently distributed across the eastern portion of the Drakensberg Escarpment, from the north-eastern Free State (South Africa) to eSwatini (formerly Swaziland). A review of the enigmatic species E. (Micrelaphinis) pumila Boheman, 1857, also presumably originating from the same broader region, reveals that only five specimens, three of which belong to the type series, are currently still traceable to accessible collections, while no further specimens have been found since the 19th century. It is here established that the type series collected by Wahlberg during the period 1838–1845 most likely originated from the Orange River valley, either in the Eastern Cape, Free State or Lesotho. As this area has been extensively transformed by agricultural and mining activities, as well as human settlements, it is hypothesized that the species may already be extinct. All the species analysed in detail are illustrated, and dichotomic keys to all species of both genera are provided to facilitate their identification.Published online: 30th April 2022
Batelka Jan, Engel Michael S. The ̒first fossil tumbling flower beetle’ larva is a symphytan (Hymenoptera)Acta Entomologica Musei Nationalis Pragae 62(1): 57-59
Abstract: A correction is provided regarding the identity of a fossil larva recently reported to represent the first Cretaceous record of its kind for the tenebrionoid family Mordellidae (Coleoptera, tumbling flower beetles). A review of the description of the specimen, however, reveals it to be a larval symphytan (order Hymenoptera), and likely of the family Pamphiliidae. The evidence for the revised identification is summarized. Published online: 30th April 2022
Gimmel Matthew L., Leschen Richard A. B.Revision of the genera of Picrotini (Coleoptera: Cryptophagidae: Cryptophaginae)Acta Entomologica Musei Nationalis Pragae 62(1): 61-109
Abstract: The genera of the Gondwanan tribe Picrotini are redefined, resulting in the recognition of 22 genera. Thirteen new genera and 10 new species are described: Austroscelis gen. nov. (type species: Cryptophagus gibbipennis Blackburn, 1892), Bellascelis gen. nov. (type species: Bellascelis pecki sp. nov.), Chileothortus gen. nov. (type species: Chileothortus infuscatus sp. nov.), Chimaerocryptus gen. nov. (type species: Chimaerocryptus johnsoni sp. nov.), Connatocryptus gen. nov. (type species: Connatocryptus utiku sp. nov.), Cordosomatula gen. nov. (type species: Cordosomatula magnabagishae sp. nov.), Foveocryptus gen. nov. (type species: Foveocryptus chenyandongi sp. nov.), Humerocryptus gen. nov. (type species: Cryptophagus tumidus Broun, 1893), Notocryptus gen. nov. (type species: Cryptophagus australis Redtenbacher, 1868), Odontosomatula gen. nov. (type species: Odontosomatula carltoni sp. nov.), Orthoscelis gen. nov. (type species: Orthoscelis transversus sp. nov.), Papuacryptus gen. nov. (type species: Papuacryptus striatopunctatus sp. nov.), Paragnetaria gen. nov. (type species: Paragnetaria slipinskii sp. nov.). Brounina Bruce, 1943, syn. nov., is recognized as a new junior synonym of Chiliotis Reitter, 1875. Fourteen new combinations are established. The genus Micrambina Reitter, 1878 and its type species, Micrambina amitta Reitter, 1878, are excluded from Cryptophagidae and transferred to the Toramini (Erotylidae: Cryptophilinae) as genus et species inquirenda. Cryptophagus hispidulus Broun, 1880, syn. nov., and Cryptophagus obscurus Broun, 1893, syn. nov., are proposed as new junior synonyms of Notocryptus australis (Redtenbacher, 1868), comb. nov. A lectotype is designated for Mycetaea pilosella Blackburn, 1891. A key is provided for the genera of Picrotini along with a habitus image gallery of putative species. The morphology of the Cryptophagidae is discussed, with an emphasis on the aedeagus and the bipartite penis as potential support for monophyletic groups within the currently heterogeneous Cucujoidea.Published online: 21st June 2022

Abstract: Two allied and little-known genera, Bulborhodopis Breuning, 1948 and Mimapatelarthron Breuning, 1940 (Coleoptera: Cerambycidae: Lamiinae: Desmiphorini), are newly recorded from China upon the discoveries of Bulborhodopis barbicornis Breuning, 1948 and B. humeralis sp. nov. from Yunnan, and Mimapatelarthron laosense Breuning, 1968 from Yunnan and Hainan. Description and illustrations of the habitus, endophallic structure and major diagnostic features for the involved taxa are provided.Published online: 21st June 2022
Souma JunTwo new species of the genus Omoplax (Hemiptera: Heteroptera: Tingidae) from Mukojima Island, with new records of lace bugs endemic to the Ogasawara Islands, JapanActa Entomologica Musei Nationalis Pragae 62(1): 117-127
Abstract: This study describes two new species of the lace bug genus Omoplax Horváth, 1912 (Hemiptera: Heteroptera: Tingidae) from Mukojima Island, the Ogasawara Islands, Japan, under the names O. karubei sp. nov. and O. mukojimensis sp. nov. These new species differ from the other species of Omoplax mainly in the shape of the pronotum and hemelytron. In all, five species belonging to two endemic genera are recognized from the Ogasawara Islands: Acanthomoplax tomokunii Souma & Kamitani, 2021, Omoplax desecta (Horváth, 1912), O. karubei sp. nov., O. majorcarinae Guilbert, 2001, and O. mukojimensis sp. nov. Additionally, several new records of tingid taxa endemic to these islands are provided: Acanthomoplax tomokunii Souma & Kamitani, 2021 from Ototojima Island, and Omoplax desecta (Horváth, 1912) from the Mukojima Group, and Meijima, Mukohjima and Nakoudojima islands. An updated key to the species is presented to facilitate the identification of Ogasawaran lace bugs.Published online: 21st June 2022
Yin Zi-WeiDiscovery of mysterious Pakistatyrus in Tibet (Coleoptera: Staphylinidae: Pselaphinae)Acta Entomologica Musei Nationalis Pragae 62(1): 129-135
Abstract: The monotypic genus Pakistatyrus Hlaváč, 2006 of the tribe Tyrini (Staphylinidae: Pselaphinae) previously contained a single species described based on two museum specimens found in northern Pakistan. Here I describe P. inconspicuus sp. nov. from a high-altitude area of Tibet. This species differs from P. ater Hlaváč, 2006 in reddish-brown coloration of the body, simple male antennae and metatibiae, and a much broader median lobe of the aedeagus. Both known species are probably locally endemic and have limited dispersal abilities, suggested by their greatly reduced elytra and lack of functional wings. A record of a second species from Tibet, which is represented by a female, is given.Published online: 11th July 2022
Tasaku Yuto, Maruyama MunetoshiTaxonomy of the intertidal athetine genus Eubadura stat. nov. (Coleoptera: Staphylinidae: Aleocharinae) from Japan, with descriptions of two new speciesActa Entomologica Musei Nationalis Pragae 62(1): 137-144
Abstract: The genus Eubadura Sawada, 1990 stat. nov. (Athetini: Athetina) which has formerly been regarded as a subgenus of the genus Atheta Thomson, 1858, from Japan is revised. The genus Osakatheta Maruyama, Klimaszewski & Gusarov, 2008 is synonymized with Eubadura. Four species are recognized in the genus: Eubadura akiensis (Sawada, 1990), comb. nov. (Japan: Hokkaidô, Honshû, Shikoku, Kyûshû), E. yasukoae (Maruyama, Klimaszewski & Gusarov, 2008), comb. nov. (Japan: Honshû; Korea), E. onoi sp. nov., (Japan: Honshû) and E. hokkaidensis sp. nov. (Japan: Hokkaidô). Key to the species is given, and a systematic position of Eubadura is discussed.Published online: 12th July 2022

Abstract: A taxonomic review of the tenebrionid genus Psammocryptus Kraatz, 1865 (Coleoptera: Tenebrionidae: Pimeliinae: Tentyriini) is given. Species of this genus are distributed in the south of Russia (Caspian depression), Transcaucasia, Kazakhstan and Central Asia, Afghanistan and Pakistan, occurring in areas with salty soil, often in tugay forests of river basins. Two new species and one new subspecies are described: P. bogatchevi Nabozhenko, Chigray & Bekchanov, sp. nov. (Kazakhstan: Syrdarya basin, Kyzylkum desert; Uzbekistan: Amudarya lower reaches and delta, Syrdarya basin, Kyzylkum desert); P. kompantsevae Nabozhenko & Chigray, sp. nov. (Uzbekistan and Tajikistan: Amudarya, upper river basin); P. bayeri vachshianus Nabozhenko & Chigray, subsp. nov. (Tajikistan: Vakhsh River valley). The nominotypical subspecies P. bayeri bayeri Koch, 1943 occurs in Turkmenistan (Tejen valley and Amudarya valley middle river course) and Tajikistan (a new record for the country: Kafirnigan River valley). Psammocryptus minutus (Tauscher, 1812) is recorded for Armenia for the first time, but the population from Yerevan has become extinct due to urbanization. The following synonymy is restituted: Psammocryptus minutus (Tauscher, 1812) = P. bergi Kuzin 1934, syn. restit.Published online: 8th October 2022
Benda Daniel, Pohl Hans, Beutel Rolf G., Straka JakubTwo new species of Xenos (Strepsiptera: Xenidae), parasites of social wasps of the genus Mischocyttarus (Hymenoptera: Vespidae) in the New WorldActa Entomologica Musei Nationalis Pragae 62(1): 185-195
Abstract: Two new species of Strepsiptera of the genus Xenos Rossi, 1793 (Xenidae) from the New World are described. Both are endoparasites of social wasps of the genus Mischocyttarus Saussure, 1853 (Vespidae: Mischocyttarini). Xenos bicolor Benda & Straka, sp. nov., parasitizes Mischocyttarus navajo Bequaert, 1933, Mischocyttarus flavitarsis (Saussure, 1854), and Mischocyttarus pallidipectus (Smith, 1857), whereas Xenos pallens Benda & Straka, sp. nov., is a parasite of Mischocyttarus costaricensis Richards, 1945 (Vespidae: Polistinae: Mischocyttarini). Diagnoses and descriptions of female cephalothoraces are presented for all three species that parasitize species of Mischocyttarus. Diagnoses and descriptions of male cephalothecae are presented for Xenos bicolor sp. nov. and Xenos pallens sp. nov. Additionally, a key for Xenos species parasitic on Mischocyttarus is provided based on characters of the female cephalothorax and male cephalotheca. Identification of Xenos species based on external morphology is discussed.Published online: 8th October 2022
Cho Hee-Wook, Kwon Min Chul, Kim Sang Ki, Beutel Rolf G.Morphology of larvae and pupae of the genus Autocrates (Coleoptera: Trictenotomidae) and its phylogenetic implicationsActa Entomologica Musei Nationalis Pragae 62(1): 197-210
Abstract: The trictenotomid genus Autocrates Thomson, 1860 is remarkable for its large and robust adults, but its larval morphology and bionomics have been unknown over the last 160 years. Here, we describe and illustrate in detail the eggs, and also the first and last instar larva and the pupa of Autocrates maqueti Drumont, 2006, based on specimens reared from identified adults collected in South Korea. The first instar larva is very similar to the known trictenotomid larvae of the genus Trictenotoma Gray, 1832, sharing the following features: distinctly flattened and parallel-sided, well-sclerotized head and largely unpigmented postcephalic body, lyre-shaped frontal arms, very short coronal suture, five pairs of stemmata, asymmetrical and tridentate mandibles with mola, simple and apically upturned urogomphi, and absence of longitudinal ridges on the thorax and abdomen. Differences occur in the primary chaetotaxy. The last instar larva is almost identical with Trictenotoma in general appearance, but the longitudinal tergal ridges of Autocrates are much denser and more widely distributed than those of Trictenotoma. Our preliminary assessment of features of immature stages confirms a close relationship of Trictenotomidae with the “salpingid group”, i.e. Salpingidae, Boridae, Pyrochroidae and Pythidae. A sister group relationship with Pythidae is likely. The putative synapomorphy is the subdivision of the ventral element of tergites IX, even though this condition is not visible in the first instars of Autocrates, and quite indistinct (but recognizable) in the last larval stage. The complete mitochondrial genome of A. maqueti is provided. A preliminary phylogenetic analysis of trictenotomid species is presented using two mitochondrial genes (16S and COI). The morphology of eggs and biological information on feeding and oviposition behaviors are also provided with photographs of adults and eggs.Published online: 25th October 2022
Zámbó András, Baňař Petr, Kovács Szilvia, Kondorosy ElődDrymini of Madagascar, with description of a new genus and three new species (Hemiptera: Heteroptera: Rhyparochromidae)Acta Entomologica Musei Nationalis Pragae 62(1): 211-223
Abstract: Malgadrymus Zámbó & Kondorosy, gen. nov., the first endemic genus of Drymini (Hemiptera: Heteroptera: Pentatomomorpha: Lygaeoidea: Rhyparochromidae: Rhyparochrominae), with two new species is described from Madagascar. A key to the species is provided and relationships to other drymine genera are discussed. Appolonius madagascariensis Zám- bó & Kondorosy, sp. nov., the first member of the genus from the island, is described from Madagascar. A list of Malagasy Drymini, including 5 genera and 16 species (3 undescribed), and a key to the genera from Madagascar are given. We provide new distribution data for the following species: Salaciola acutangulata Slater, 1994, Salaciola caliginosa Slater, 1989, Salaciola nana Bergroth, 1906, Salaciola signaticornis Linnavuori, 1978, Sinierus capensis Dallas, 1852, and Sinierus nudus Scudder, 1984. Salaciola nana is also recorded from the Republic of the Congo for the first time.Published online: 25th October 2022
Hansen Aslak K., Brunke Adam, Simonsen Thomas, Solodovnikov AlexeyRevision of Quedius sensu stricto (Coleoptera: Staphylinidae)Acta Entomologica Musei Nationalis Pragae 62(1): 225-299
Abstract: We here present the first integrative revision of the subgenus Quedius Stephens, 1829 sensu stricto where taxonomic decisions are based on morphology, genomic phylogeny (published elsewhere) and single locus DNA evidence. The subgenus is restricted to the Holarctic region and includes some of the largest, most robust members of the genus Quedius. For species delimitation, a total of 200 COI barcodes covering nearly all species within the subgenus were evaluated through phylogenetic, cluster and network analysis. Taxonomic, distributional and bionomic data, all hitherto published and new are synthesized and an identification key is constructed for all species. All 20 species of Quedius s. str. are divided into five species groups based on genomic phylogeny, morphology, distributional patterns and practical considerations. Overall, there was good congruence among various lines of evidence. As exceptions, high COI barcode variability was found within the wingless and patchily distributed Q. unicolor Kiesenwetter, 1847 and Q. sundukovi Smetana, 2003 (3 and 5 BOLD BINs, respectively) from the Q. molochinus-group without corresponding morphological or geographic patterns. On the contrary, in the Q. pallipes-group very little divergence in the COI barcode was found between clearly morphologically separated species. From the taxonomically challenging Nearctic Quedius molochinoides-group, Quedius altanai Hansen & Brunke sp. nov. is described as new species from the central and southern Rockies, rendering Q. lanei Hatch, 1957 to be restricted to the eastern foothills of the Cascades, Sierra Nevada and Blue Mountains. In the case of Q. subunicolor and Q. altaicus, continuous morphological and COI variation firmly established the earlier suspected synonymy Quedius subunicolor Korge, 1961 = Quedius altaicus Korge, 1962 syn. nov. Other new synonyms established here are: Quedius pallipes Lucas, 1849 = Quedius simplicifrons Fairmaire, 1861 syn. nov. = Quedius levasseuri Coiffait, 1964 syn. nov.; Quedius hispanicus Bernhauer, 1898 stat. reinstituted = Quedius cobosi Coiffait, 1964 syn. nov.; Quedius fuliginosus (Gravenhorst, 1802) = Quedius latus Hochhuth, 1851 syn. nov. = Quedius viduus Sawada, 1965, syn. nov. Quedius gracilis Stephens, 1832 syn. rev. is moved from synonymy with Q. fuliginosus and placed into synonymy with Q. curtipennis Bernhauer, 1908, the younger being the valid name due to prevailing usage in accordance with the ICZN Article 23.9; Quedius hammianus Sharp, 1911 syn. revid., Q. secundus Last, 1952 syn. revid., and Q. rufulus Blümml, 1898 syn. revid., are moved from synonymy with Q. simplicifrons and placed into synonymy with Q. hispanicus Bernhauer, 1898; Quedius sardous Gridelli, 1924 syn. revid., and Q. leonhardi Bernhauer, 1914 syn. revid., are moved from synonymy with Q. molochinus (Gravenhorst, 1806) to synonymy with Q. pallipes. Human mediated dispersals, most likely through the historical transport of ship ballast, are noted as regular phenomenon for some members of the subgenus. Quedius fuliginosus, Q. curtipennis and Q. molochinus, introduced from the Palearctic to the Nearctic, are the most noticeable examples.Published online: 26th November 2022
