Yasunaga Tomohide, Schwartz Michael D., Chérot FrédéricRevision of the plant bug genus Diognetus, with descriptions of thirteen new species from the Oriental and Eastern Palearctic Regions (Hemiptera: Heteroptera: Miridae)Acta Entomologica Musei Nationalis Pragae 63(1): 1-55
Abstract: The mirine plant bug genus Diognetus Distant, 1904 (Hemiptera: Heteroptera: Miridae: Mirinae: Mirini) is revised. Eighteen Oriental and Eastern Palearctic species are properly assigned to the genus. Diplotrichiella Poppius, 1915, syn. nov. and Yamatolygus Yasunaga, 1994, syn. nov. are synonymized with Diognetus; accordingly the following two new combinations, one substitute name and one new synonymy are proposed: Diognetus flavigenis (Horváth, 1905) comb. nov. and D. insulanus (Yasunaga, 1994) comb. nov. (transferred from Yamatolygus); D. yamato Yasunaga nom. nov. for Yamatolygus pilosus Yasunaga, 1994, junior secondary homonym of D. pilosus (Poppius, 1914); and Diplotrichiella rufescens Poppius, 1914, syn. nov. = Diognetus intonsus Distant, 1904 (valid name). Thirteen species are described as new: Diognetus bagmaticus sp. nov. (from Nepal), D. cheimon sp. nov. (Japan), D. dhampus sp. nov. (Nepal), D. duwalorum sp. nov. (Nepal), D. giganteus sp. nov. (Malaysia), D. gotohi sp. nov. (Malaysia), D. laureus sp. nov. (Japan), D. magnificus sp. nov. (Indonesia), D. minusculus sp. nov. (Malaysia), D. puspae sp. nov. (Nepal), D. schuhorum sp. nov. (Indonesia), D. styrax sp. nov. (Taiwan) and D. vernus sp. nov. (Japan). The generic characters are reassessed and discussed, on the basis of detailed observation of external structures using scanning electron microscopy as well as male and female genitalia.Published online: 12th March 2023
Hájek Jiří, Šťastný Jaroslav, Hendrich Lars, Balke MichaelA review of the genus Platynectes from the Solomon Islands (Coleoptera: Dytiscidae: Agabinae)Acta Entomologica Musei Nationalis Pragae 63(1): 57-74
Abstract: Seven new species of the genus Platynectes Régimbart, 1879 from the Solomon Islands are described: Platynectes barana sp. nov., P. mbaole sp. nov., P. popomanaseu sp. nov. (all from Guadalcanal), P. lunga sp. nov. (Guadalcanal and Savo), P. malaita sp. nov. (Malaita), P. makira sp. nov. (Makira) and P. owaraha sp. nov. (Makira and Owaraha). Platynectes insularis J. Balfour-Browne, 1939, described from Vanuatu and the Solomons, currently considered a junior subjective synonym of P. semperi Régimbart, 1899, is reinstituted as a valid species based on its morphology and a molecular analysis by Toussaint et al. (2017). The paratypes of P. insularis from the Solomons are shown to belong to a new species – P. owaraha sp. nov., and, thus, the distribution of P. insularis is restricted to Vanuatu. Habitus and male genitalia are illustrated for all seven new species and P. insularis. A checklist of Dytiscidae so far recorded from the Solomon Islands and Vanuatu is appended.Published online: 12th March 2023
Jiang Zhuo-Yin, Zhao Shuang, Mai Zu-Qi, Jia Feng-Long, Hendrich LarsReview of the genus Cybister in China, with description of a new species from Guangdong (Coleoptera: Dytiscidae)Acta Entomologica Musei Nationalis Pragae 63(1): 75-102
Abstract: The genus Cybister Curtis, 1827 is reviewed with respect to the fauna of China. A new species, Cybister (Melanectes) danxiaensis sp. nov. is described and illustrated. Altogether, 16 Cybister species are recorded from China, although the status of two of them remains in question. All species are diagnosed, with their habitus and male genitalia illustrated. Additional faunistic data from China are provided for the following species: C. guerini Aubé, 1838 from Hainan; C. lewisianus Sharp, 1873 from Guangdong and Hainan; C. limbatus (Fabricius, 1775) from Guangdong, Guangxi and Hainan; C. rugosus (W. S. Macleay, 1825) from Chongqing, Guangdong, Hubei, Hunan, Jiangxi, Yunnan, Zhejiang; C. tripunctatus lateralis (Fabricius, 1798) from Chongqing, Guangxi, Jiangxi, Shanghai; C. brevis Aubé, 1838 from Guizhou, Hunan, Zhejiang; and C. sugillatus Erichson, 1834 from Guangxi and Yunnan. An updated identification key and distribution maps for all species are provided. Cybister lateralimarginalis torquatus (Fischer von Waldheim, 1829) is recorded for the first time from Tajikistan and Uzbekistan.Published online: 12th March 2023
Bilton David T.New species and new records of minute moss beetles from East Africa (Coleoptera: Hydraenidae)Acta Entomologica Musei Nationalis Pragae 63(1): 103-110
Abstract: Despite much recent progress, knowledge of Afrotropical Hydraenidae remains limited, particularly in areas experiencing tropical climates, where large numbers of species likely remain undetected. Here, three new species are described from material recently col­lected from two Malawian mountains: Coelometopon dedzae sp. nov. from Mount Dedza and Hydraena (Hydraenopsis) mulanje sp. nov. and Ochthebius (Asiobates) erinaceus sp. nov. from Mount Mulanje. All specimens were sampled by sifting, and Hydraena mulanje sp. nov. and Ochthebius erinaceus sp. nov. appear to be terrestrial, in forest litter. Specimens of Decarthrocerus Orchymont, 1948 from Mount Dedza are apparently referable to D. jeanneli Orchymont, 1948, described from Mount Elgon, Kenya, as is a specimen examined from Mount Hanang in Tanzania. These represent new country records for this species, which appears to be widespread in East African Mountains.Published online: 12th March 2023

Abstract: Five species of the Lathrobium nomurai group are (re)described: Lathrobium nomurai Nakane, 1955, L. fujimotoi Y. Watanabe, 2001, L. hikosanense Y. Watanabe, 1998, L. yufuense sp. nov., and L. denchu sp. nov. All species inhabit the upper hypogean zone or are found under stones in the northern Kyushu, Japan. Their distribution patterns are discussed and compared to other members of this species group.Published online: 6th May 2023
Toledo Mario, Bilton David T., Balke Michael, Schizzerotto Antonio, Villastrigo AdriánA new, putatively semisubterranean, Rhithrodytes diving beetle from southwestern Sardinia (Coleoptera: Dytiscidae)Acta Entomologica Musei Nationalis Pragae 63(1): 125-133
Abstract: The diving beetle genus Rhithrodytes Bameul, 1989 is endemic to areas surrounding the Western Mediterranean Basin, and currently includes six lotic species; three each in Europe and North Africa. Here we describe a striking new species, Rhithrodytes pantaleonii sp. nov., discovered during recent fieldwork in southwestern Sardinia. The new species differs markedly from the only previously known Rhithrodytes from the Tyrrhenian Islands, R. sexguttatus (Aubé, 1838). The pale, flattened appearance of R. pantaleonii sp. nov., together with its small eyes and scarcity during collecting, all point to it being semisubterranean. A combination of mitochondrial and nuclear DNA sequences, obtained non-destructively from the holotype, allow us to reconstruct the evolutionary history and historical biogeography of this taxon and take the opportunity to publish the mitogenome of the new species. Rhithrodytes pantaleonii sp. nov. is shown to be sister to R. sexguttatus, these taxa apparently having diverged during the Miocene, when the Sulcis-Iglesiente region of southwestern Sardinia was separated from the rest of Corsico-Sardinia by the Sardinian Seaway. Our discovery adds to our understanding of the biogeography of the Tyrrhenian Islands, and further highlights the importance of the Sulcis-Iglesiente region as an area of endemism in its own right.Published online: 6th May 2023
Bidzilya Oleksiy, Karsholt Ole, Šumpich JanA revision of the genus Ivanauskiella (Lepidoptera: Gelechiidae)Acta Entomologica Musei Nationalis Pragae 63(1): 135-164
Abstract: We revise the genus Ivanauskiella Ivinskis & Piskunov, 1980. Six new species are described: I. sutteri sp. nov. (Greece: Crete), I. bovis sp. nov. (Morocco), I. nigripunctata sp. nov. (Spain), I. annekristinae sp. nov. (France: Corsica), I. limoniella sp. nov. (Bulgaria, Ukraine, Turkey, Russia), I. albimarginata sp. nov. (Armenia, Iran). Ivanauskiella turkmenica Ivinskis & Piskunov, 1980, sp. restit., is reinstated as a separate species from synonymy with I. psamathias (Meyrick, 1891). Updated distribution records are provided for all ten species recognised in Ivanauskiella. Illustrations of adults, and male and female genitalia are provided, as well as data on the DNA barcode when available.Published online: 11th May 2023
Zhang Wen-Xuan, Yin Zi-WeiFeabatrus gen. nov., a conspicuous new genus of Batrisitae from Myanmar and China (Coleoptera: Staphylinidae: Pselaphinae)Acta Entomologica Musei Nationalis Pragae 63(1): 165-175
Abstract: A highly distinctive genus of pselaphine tribe Batrisini, Feabatrus gen. nov., is described based on Leonardo Fea’s historical collection housed in the Museo Civico di Storia Naturale “G. Doria” di Genova, Italy. The genus includes two new species from Myanmar, F. myanmarensis sp. nov. and F. leonardoi sp. nov. Feabatrus gen. nov. is characterized and can be separated from related genera by large-sized body with long, suberect setae on the dorsal surface and antennae, pronotum with large marginal, discal and antebasal spines, elytra with a smooth disc and shallow discal striae, inner two basal foveae close, and lacking subhumeral fovea, distinct constriction between the elytra and the abdomen, and the female possessing an asymmetric genital complex as well as a flat, sub-trapezoidal tergite 5 (VIII) that has a small nodule in the middle of the posterior margin. A single female from Yunnan, southwestern China, representing a third species, is briefly described but left unnamed.Published online: 4th June 2023

Kasalo Niko, Yong Sheyla, Rebrina Fran, Skejo JosipDefinition of the tribe Metrodorini (Orthoptera: Tetrigidae) with notes on biogeography and evolution of Metrodorinae and CladonotinaeActa Entomologica Musei Nationalis Pragae 63(1): 187-193
Abstract: Both Metrodorinae and Cladonotinae are polyphyletic subfamilies of Tetrigidae and are thus in need of revision. This paper offers a key step toward this by defining the nominotypical tribe of Metrodorinae, Metrodorini Bolívar, 1887 that encompasses mostly apterous species with arcuate median carina of pronotum, laterally projecting lateral lobes of pronotum, and produced carinae of vertex forming horns. The tribe Metrodorini consists of the following genera: Cota Bolívar, 1887; Hancockiella Cadena-Castañeda & Cardona, 2015; Metrodora Bolívar, 1887; Miriatra Bolívar, 1906; Antillotettix Perez-Gelabert, 2003; Armasius Perez-Gelabert & Yong, 2014; †Baeotettix Heads, 2009; Bahorucotettix Perez-Gelabert, Hierro & Otte, 1998; Cubanotettix Perez-Gelabert, Hierro & Otte, 1998; Cubonotus Perez-Gelabert, Hierro & Otte, 1998; †Electrotettix Heads & Thomas, 2014; Haitianotettix Perez-Gelabert, Hierro & Otte, 1998; Hottettix Perez-Gelabert, Hierro & Otte, 1998; Mucrotettix Perez-Gelabert, Hierro & Otte, 1998; Sierratettix Perez-Gelabert, Hierro & Otte, 1998; Tiburonotus Perez-Gelabert, Hierro & Otte, 1998; and Truncotettix Perez-Gelabert, Hierro & Otte, 1998. The following new synonyms are recognized: Metrodorini = Miriatrini Cadena-Castañeda & Cardona, 2015, syn. nov. = Mucrotettigini Cadena-Castañeda & Silva, 2019, syn. nov. Eleleus curtus Bolívar, 1887 is excluded from Metrodorini and is left under Cladonotinae without tribal assignment. Biogeography, evolution, and taxonomies of Metrodorinae and Cladonotinae are briefly discussed.Published online: 28th July 2023
Selis MarcoRevision of the genus Allorhynchium in the Philippine Islands (Hymenoptera: Vespidae: Eumeninae)Acta Entomologica Musei Nationalis Pragae 63(1): 195-205
Abstract: The Philippine species of the genus Allorhynchium van der Vecht, 1963 are revised, with three species recognized: A. angulatum sp. nov., A. cariniventre Giordani Soika, 1986, and A. quadrituberculatum (von Schulthess, 1913) (= A. violaceipenne Gusenleitner, 2003, syn. nov.). Three additional species, Allorhynchium argentatum (Fabricius, 1804), A. chinense (de Saussure, 1862), and A. snelleni (de Saussure, 1862), are excluded from the Philippine fauna.
