Fikáček Martin, Matsumoto Keita, Perkins Philip, Prokin Alexander, Sazhnev Alexey, Litovkin Stanislav, Jäch Manfred A.The family Epimetopidae (Coleoptera: Hydrophiloidea): review of current knowledge, genus-level phylogeny, and taxonomic revision of EupotemusActa Entomologica Musei Nationalis Pragae 61(1): 1-34
Abstract: Epimetopidae are a small beetle family of the superfamily Hydrophiloidea, comprising 72 described species in three genera: the American Epimetopus Lacordaire, 1854 (56 species), Asian Eumetopus Balfour-Browne, 1949 (eight species) and African Eupotemus Ji & Jäch, 1998 (eight species, of which six are described as new here). In this study we illustrate and compare the adult morphology of all three genera and generate the first DNA sequences for Eumetopus and Eupotemus. The morphological data and sequences of four genes (cox1, 16S, 18S and 28S) are used to reconstruct phylogenetic relationships among genera. Both strongly support the monophyly of Epimetopidae, reveal Eumetopus as the earliest diverging taxon and Epimetopus + Eupotemus as a strongly supported clade with numerous synapomorphies. The reciprocal monophyly of Epimetopus and Eupotemus is strongly supported by DNA data but not in the morphological analysis which reveals Epimetopus paraphyletic. Eumetopus, despite being the earliest branching clade, is characterized by many unique derived structures, e.g. by the presence of the sperm pump in males (unique in Hydrophiloidea). The available data on the biology of Epimetopidae indicate that most species inhabit sandy to muddy margins of streams or rivers. Females of all three genera carry egg cases; Epimetopidae hence are one of three independent lineages of Hydrophiloidea in which this behavior evolved. Larvae are only known for Epimetopus and are characterized by morphological adaptations for feeding by piercing and sucking, a closed tracheal system and abdominal gills; larvae of Eumetopus and Eupotemus remain unknown and further research is needed to confirm whether they show the same adaptations as Epimetopus. The taxonomy of the African genus Eupotemus is re­vised, with six species described as new: E. bilobatus sp. nov. (Nigeria), E. cameroonensis sp. nov. (Cameroon), E. ophioglossus sp. nov. (Gabon, Togo), E. smithi sp. nov. (Côte d’Ivoire), E. taianus sp. nov. (Côte d’Ivoire) and E. uluguru sp. nov. (Tanzania). Eupotemus limicola Delève, 1967 is fixed as the type species of the genus according to ICZN (1999: Art. 70.3). New records of Eumetopus species are provided (E. acutimontis Ji & Jäch, 1998 from Vietnam, E. bullatus (Sharp, 1875) from India: Maharashtra, E. flavidulus (Sharp, 1890) from India: Maharashtra and Andhra Pradesh, E. maindroni (Régimbart, 1903) from India: Maharashtra and Gujarat, and E. weigeli Skale & Jäch, 2003 from India: Uttarakhand). The habitus of all species is illustrated. An updated checklist of the Epimetopus species is provided, and records of two specimens of the E. costatus group from Zambia and Saudi Arabia are considered to result from either accidental introductions or mislabelling.Published online: 3rd February 2021

Fery Hans, Hájek JiříNomenclatural and taxonomic notes on some species of Gyrinidae (Coleoptera)Acta Entomologica Musei Nationalis Pragae 61(1): 55-71
Abstract: Nomenclatural notes on the names of several species in the family Gyrinidae are provided. Six specific names are found to be junior homonyms. Three of them are replaced by nomina nova: Aulonogyrus marginatus (Aubé, 1838) by Aulonogyrus charlesaubei nom. nov., Gyrinus dubius Wallis, 1926 by Gyrinus suspectus nom. nov., and Macrogyrus (Andogyrus) colombicus australis (Brinck, 1977) by Macrogyrus (Andogyrus) colombicus brincki nom. nov. The other three junior homonyms were never considered congeneric with senior homonyms after the year 1899, and thus cannot not be replaced by new names: Gyretes dorsalis (Brullé, 1837), Macrogyrus australis (Brullé, 1835), and Andogyrus glaucus (Aubé, 1838); it is proposed that these names will be conserved by a ruling of the International Commission on Zoological Nomenclature. It is found that Enhydrus sulcatus (Forsberg, 1821) is a primary homonym and a junior subjective synonym of Enhydrus sulcatus (Wiedemann, 1821) in Wiedemann & Germar (1821). The neotype is designated for Gyrinus striatus Fabricius, 1792, which is a senior primary homonym and a senior subjective synonym of G. striatus Olivier, 1792 (both currently in Aulonogyrus Motschulsky, 1853). Gyrinus striatus was published by Olivier not only in 1792, but again in the year 1795 (so far treated as the correct publishing year). To stabilise the nomenclature, one and the same specimen is designated simultaneously as the neotype for Gyrinus striatus Olivier, 1792, and G. striatus Olivier, 1795, and thus both names become objective synonyms. Gyrinus ovatus Klug, 1829 is a senior subjective synonym of Gyrinus gibbus Aubé, 1838 syn. nov. and of Gyrinus apicalis Sharp, 1878 syn. nov. Gyrinus racenisi Ochs, 1953 must be used as the valid name for Gyrinus ovatus sensu Aubé (1838b) (nec Klug 1829). Lectotypes are designated for Gyrinus apicalis Sharp, 1878, Gyrinus gibbus Aubé, 1838, Gyrinus ovatus Klug, 1829, and Gyrinus paykulli Ochs, 1927b. Type specimens and diagnostic characters are illustrated for G. striatus Fabricius, G. striatus Olivier, G. ovatus Klug, G. racenisi and G. paykulli.Published online: 24th February 2021
Liston Andrew, Prous MarkoStenocephus janseni sp. nov., a new species of stem-sawfly from Germany (Hymenoptera: Cephidae)Acta Entomologica Musei Nationalis Pragae 61(1): 73-81
Abstract: Stenocephus janseni sp. nov. (Hymenoptera: Cephidae) is described from Brandenburg, eastern Germany, known only from the female holotype. It possesses an unusual combination of “generic” morphological characters, which makes its placement in Stenocephus Shinohara, 1999 provisional. Compared to other Stenocephus species, differences in the morphology of the lancet are particularly striking. Genetic data for S. janseni sp. nov. place it unequivocally in the Hartigiini, but rather distantly from other genera of this tribe which have so far been sequenced. The three previously described Stenocephus species are recorded from the East Palaearctic. No genetic data are currently available for these. Pachycephus nigratus Dovnar-Zapolskij, 1931, comb. restit., is no longer treated as belonging to Phylloecus Newman, 1838, but as a member of the genus in which it was originally described.Published online: 1st March 2021
González-Obando Ranulfo, Carrejo-Gironza Nancy, Mendivil-Nieto Julián, García Aldrete Alfonso NeriNeurostigma (Psocodea: Psocomorpha: Epipsocidae) from Colombia: new species and an identification keyActa Entomologica Musei Nationalis Pragae 61(1): 83-98
Abstract: Upon examination of recently collected epipsocid barklice from natural areas of Colombia, five new species of Neurostigma Enderlein, 1900 were found: N. lienhardi sp. nov., N. mockfordi sp. nov., N. newi sp. nov., N. thorntoni sp. nov., and N. valderramae sp. nov. They are here described and illustrated. A cladistic analysis of 32 morphological characters indicates that Neurostigma is monophyletic. An updated key for the identification of males of the described species of the genus is presented.Published online: 10th March 2021

Gapon Dmitry A.Revision of the genus Exosehirus (Heteroptera: Cydnidae), with the description of two new speciesActa Entomologica Musei Nationalis Pragae 61(1): 133-161
Abstract: The present work is a revision of the Palaearctic burrower bug genus Exosehirus Wagner, 1963 (Heteroptera: Cydnidae: Sehirinae). New data on the morphology and distribution are given. Structures of the female internal ectodermal genitalia and the completely inflated aedeagi are described and illustrated for the first time. An extended differential diagnosis as a comparison of the genus with representatives of all Palaearctic genera of the tribe Sehirini is provided. Based on characters of the terminalia of both sexes, two new species are described: E. elamensis sp. nov. from Southwest Iran, and E. essedonius sp. nov. from Kazakhstan. ‘Exosehirus’ steini (Signoret, 1884) nom. dub. is excluded from the genus Exosehirus and treated as a species incertae sedis. Exosehirus marginatus (Signoret, 1881) is recorded for Azerbaijan for the first time.Published online: 21st April 2021

Trivellone Valeria, Forte Vally, Filippin Luisa, Dietrich Christopher H.First records of the North American leafhopper Gyponana mali (Hemiptera: Cicadellidae) invading urban gardens and agroecosystems in EuropeActa Entomologica Musei Nationalis Pragae 61(1): 213-219
Abstract: The Nearctic leafhopper species Gyponana (Gyponana) mali DeLong, 1942 is reported from Europe for the fi rst time and represents the fi rst record of the tribe Gyponini Stål, 1870 (Hemiptera: Cicadellidae: Iassinae: Gyponini) for the Palearctic Region. Specimens were collected in southern Switzerland (Ticino) and two regions of northern Italy (Lombardy and Veneto) in 2015–2019. The preferred host plant in these areas appears to be Cornus sanguine L. Phylogenetic analysis of the COI barcode sequences grouped one of the European specimens with three individuals of G. (G.) mali from Ontario, Canada. Morphological study indicated that the male genitalia of the European population are intermediate between G. (G.) mali and G. (G.) extenda DeLong, 1942.Published online: 17th May 2021
Zettel Herbert, Laciny Alice, Bongo Juvy P.The genus Xenobates (Hemiptera: Veliidae) in the Philippines: overview and description of two new speciesActa Entomologica Musei Nationalis Pragae 61(1): 221-230
Abstract: The Philippine species of Xenobates Esaki, 1927 are reviewed, with the exception of the Xenobates argentatus complex. Two species are described as new: Xenobates nypicola sp. nov. and X. riedli sp. nov. The presence of Xenobates murphyi Andersen, 2000 in the Philippines is confirmed. The taxonomically unresolved Xenobates argentatus complex is represented in the Philippines by at least six morphologically very similar species, but the typical X. argentatus Andersen, 2000, a species described from Thailand, must be excluded from the Philippine fauna. An identification key to the hitherto described species of the Philippines is provided. All species are illustrated. Xenobates species inhabit a wide variety of mangrove habitats along the Philippine coasts; Xenobates nypicola sp. nov. typically inhabits coastal swamps with Nypa fruticans.Published online: 8th June 2021

Seidel Matthias, Sýkora Vít, Leschen Richard A. B., Fikáček MartinA review of the New Zealand Berosus (Coleoptera: Hydrophilidae) with descriptions of three new speciesActa Entomologica Musei Nationalis Pragae 61(1): 243-252
Abstract: The New Zealand species of the water scavenger beetle genus Berosus Leach, 1817 are reviewed based on freshly collected material and museum specimens. Four species are recognized: Berosus pallidipennis (Sharp, 1884) widespread in the North and South Islands, B. muellerorum sp. nov. from the eastern part of the North Island, and B. halasi sp. nov. and B. maru sp. nov., both endemic to central part of South Island. The synonymy of B. mergus Broun, 1886 with B. pallidipennis is confirmed and lectotypes for both taxa are designated. The larval morphology of B. pallidipennis and B. muellerorum is briefly discussed. Distributional data of all species are reported and illustrated, indicating a noticeable lack of Berosus species in the northern part of North Island and in Stewart Island and the presence of two rare species in the South Island, east of Southern Alps. An identification key to New Zealand species of the genus is provided.Published online: 3rd July 2021
Bilton David T.Differentiation of South African coastal rock pool Ochthebius is associated with major ocean currents (Coleoptera: Hydraenidae)Acta Entomologica Musei Nationalis Pragae 61(1): 253-260
Abstract: A number of non-marine coastal invertebrate species have been found to constitute (semi-) cryptic species complexes in recent years. Here it is revealed that rather than a single widespread species, distributed from the Namibian border to the Cape south coast, South African coastal rock pool Ochthebius Leach, 1815 previously referred to Ochthebius capicola (Péringuey, 1892) comprise two distinct taxa. Ochthebius capicola (s. str.) is apparently restricted to the Benguela Ecoregion on the west coast, being replaced by Ochthebius mlamboi sp. nov., in south and east coast localities influenced by the Agulhas Current, including areas of the Eastern Cape province well outside the previous known range of these beetles. The distribution and ecology of the two species is discussed, with reference to biogeographic breaks in southern African coastal taxa, and the emerging view that many ‘widespread’ coastal rock pool Ochthebius may actually be (semi-) cryptic species complexes.Published online: 5th July 2021
Roháček JindřichNew species and records of Anthomyzidae (Diptera) from the East Palaearctic, with a checklist of taxa occurring in the areaActa Entomologica Musei Nationalis Pragae 61(1): 261-288
Abstract: The knowledge of Anthomyzidae (Diptera: Acalyptratae) in the East Palaearctic area is extended by new taxonomic, biological and distributional information. Two new species of the genus Anthomyza Fallén, 1810, viz. A. aspina sp. nov. (Russia: Far East) and A. breviclavus sp. nov. (North Korea), and a species tentatively affi liated with the genus Zealantha Roháček, 2007, viz. Z. fasciolata sp. nov. (Japan) are described. Although all are based only on females, they are distinctive species unmistakably recognized by external characters and structures of the female postabdomen. Relationships of all new species are discussed. Records of 24 species are presented; 3 species are recorded from the E. Palaearctic, 1 species from continental Asia, 3 species from North Korea and a number of species from particular parts of E. Palaearctic Russia for the fi rst time. An updated checklist of East Palaearctic Anthomyzidae is presented, now comprising 13 genera and 44 species. Taxonomic notes for Anthomyza clara Roháček, 2006, Fungomyza cercata Roháček, 2009 and some other species, and new biological information for Anthomyza trifurca Sueyoshi & Roháček, 2003 are given. Longitudinal dark patterning of the wing found in A. breviclavus sp. nov., represents the fi fth lineage of Anthomyzidae in which this type of pattern has evolved independently. Species richness of Anthomyzidae in the E. Palaearctic is discussed with an estimate of about 60 species occurring in the area.Published online: 26th July 2021
Mendonca Maria Thayane S., Nunes Benedito M., Fernandes Jose Antonio M.Description of fifteen new species of the Hypoxys balteatus species group (Hemiptera: Heteroptera: Pentatomidae)Acta Entomologica Musei Nationalis Pragae 61(1): 289-318
Abstract: Hypoxys Amyot & Serville, 1843 (Hemiptera: Heteroptera: Pentatomidae: Edessinae), for a long time considered a synonym or subgenus of Edessa Fabricius, 1803, was recently revised and reinstated to the generic rank. This genus comprises 17 described species divided in four species groups: H. quadridens, H. oxyacanthus, H. triangularis, and H. balteatus species group. Also, there is a large number of new species yet to be described. The H. balteatus species group is diagnosed by: pronotum with posterior stripe smoky brown to black with black punctures within, sometimes these punctures are surrounded by small dark spots; punctures of the pronotal disc smaller and paler than those of the posterior stripe; anterolateral margin of pronotum yellow; anterior half of scutellum with punctures large, sparse, and also on dark spots; connexivum uniformly green, without dark spots; thorax ventrally with two pairs of brown to black rounded spots; apex of pseudosutures with black to brown round spots. This species group included so far only H. balteatus (Walker, 1868). Here we describe and assign 15 new species to this group: H. amyoti sp. nov. (Suriname: Powakka; French Guiana), H. aspilogaster sp. nov. (Brazil: Minas Gerais, Espírito Santo and Rio de Janeiro), H. belenensis sp. nov. (Brazil: Pará), H. bergrothi sp. nov. (Venezuela: Amazonas; French Guiana: Saint-Elie), H. breddini sp. nov. (Bolivia: Santa Cruz and San Carlos), H. caquetensis sp. nov. (Colombia: Caquetá), H. favachae sp. nov. (Suriname: Sipaliwini; Brazil: Amapá and Pará), H. gaucho sp. nov. (Brazil: Rio Grande do Sul), H. hyalinofasciatus sp. nov. (Ecuador: Sucumbíos), H. immaculatus sp. nov. (Bolivia: Beni), H. nigroantennatus sp. nov. (French Guiana: Roura), H. santarensis sp. nov. (Brazil: Pará), H. servillei sp. nov. (Brazil: Mato Grosso and Goiás), H. stysi sp. nov. (Suriname: Coronie, Sipaliwini; French Guiana: Cayenne), and H. venustus sp. nov. (Bolivia: Cochabamba). Descriptions, measurements, photos of dorsal and ventral view of each species, and of external genitalia of both sexes, an identification key, and distributional maps are presented.Published online: 7th August 2021
