Men Q.-L., Starkevich P., He L.-F., Shi J.-X., Shi M.-Y., Zhang Z.-X., Hu J.-H., Chen A., Zhang Y.-X.Tipula (Vestiplex) from Yunnan and Tibet, China: one new species and redescriptions of five known species (Diptera: Tipulidae)Acta Entomologica Musei Nationalis Pragae 61(2): 341-362
Abstract: A new crane fly species Tipula (Vestiplex) lushuiensis Men & Starkevich, sp. nov., is described and illustrated based on materials collected in Yunnan and Tibet, China. Tipula (V.) alyxis Alexander, 1963, T. (V.) guibifida Yang & Yang, 1992, T. (V.) himalayensis Brunetti, 1911, T. (V.) quasimarmoratipennis Brunetti, 1912 and T. (V.) reposita Walker, 1848 are redescribed and illustrated based on additional morphological characters. Tipula (V.) quasimarmoratipennis and T. (V.) reposita are listed as new records for the Chinese fauna. Male of T. (V.) quasimarmoratipennis and females of T. (V.) alyxis, T. (V.) guibifida and T. (V.) himalayensis are illustrated for the first time.Published online: 22nd September 2021
Grebennikov V. V., Anderson R. S. Yagder serratus, a new eyeless weevil from Mexico and the non-monophyly of Brachycerinae, the evolutionary twilight zone of true weevils (Coleoptera: Curculionidae)Acta Entomologica Musei Nationalis Pragae 61(2): 363-374
Abstract: We describe and illustrate a new eyeless weevil, Yagder serratus gen. & sp. nov., based on a single adult female collected by sifting forest leaf litter in Mexico. A phylogenetic analysis of 39 terminals and 2679 aligned positions from three DNA fragments places the new species into the subfamily Brachycerinae (as incertae sedis) and outside the highly diversified clade of ‘higher’ true weevils. Neither Brachycerinae, nor its tribe Raymondionymini traditionally uniting most eyeless weevils, are monophyletic unless the latter is limited to a Mediterranean core group. Both these taxa are taxonomic dumping-grounds likely containing species-poor sisters of species-rich clades. When resolved, the subfamily Brachycerinae will be likely split into two or more species-poor deeply-divergent subfamilies. Published online: 22nd September 2021
Yamada Kazutaka, Yasunaga TomohideThe tribe Anthocorini in Japan (Hemiptera: Anthocoridae): descriptions of new species, review of distribution and bionomicsActa Entomologica Musei Nationalis Pragae 61(2): 375-426
Abstract: Japanese Anthocorini are reviewed. A total of five genera and 13 species were identified, including two new species described below: Temnostethus mirificus sp. nov. and Anthocoris venustus sp. nov. Previous records of Anthocoris miyamotoi Hiura, 1959 from Japan are considered to be confused with A. venustus sp. nov. Anthocoris nemoralis (Fabricius, 1794), which is a common and widespread species in Europe, is recorded in Japan for the first time; it is assumed to have been accidentally introduced into Japan recently. Temnostethus distans Kerzhner, 1973 and Anthocoris kalopanacis Kerzhner, 1977 are newly recorded in Japan proper. Male and female genitalia are illustrated and described for most of the treated species. Identification keys to the genera and species that occur in Japan are provided. Bionomics are provided for each species. Detailed locality information and distribution maps in Japan are presented for all Japanese species and their zoogeography is discussed.

Asano MakotoThe larval structures and bionomics of Idgia iriomoteana (Coleoptera: Prionoceridae)Acta Entomologica Musei Nationalis Pragae 61(2): 427-434
Abstract: The life cycle, bionomics and mature larval structures of the Japanese prionocerid species, Idgia iriomoteana Nakane, 1980 were investigated in captivity. The results showed that I. iriomoteana has the following characteristics: (1) the larval morph is less advanced in terms of miniaturization, and larvae pass seven larval molts before they pupate; (2) the life cycle is univoltine with summer, not winter, dormancy; (3) the first instar larvae are larger than the size of the egg, but foetomorphic larval instar (which is observed in the Melyridae: Malachiinae) is not shown. Based on comparison with melyrid species, the degree of miniaturization, dormancy behaviour, adaptation to the tropical and subtropical climates and the adaptive significance of a large first instar larva are all discussed. This study is the first to report the complete life cycle of a member of the family Prionoceridae.Published online: 22nd October 2021
Kaplin Vladimir, Shakula GeorgiyNew species of bristletails of the family Machilidae (Archaeognatha) from KazakhstanActa Entomologica Musei Nationalis Pragae 61(2): 435-445
Abstract: The fauna of bristletails of the family Machilidae in Kazakhstan currently includes one species of the genus Silvestrichiloides Mendes, 1990 and 13 species of the genus Allopsontus Silvestri, 1911. The present study describes one new species of the genus Silvestrichiloides (S. berkarensis Kaplin, sp. nov. from South Kazakhstan) and two new species of the genus Allopsontus (A. (Kaplinilis) nigrostriatus Kaplin, sp. nov. and A. (Machilanus) perfectus Kaplin, sp. nov. from Southeastern Kazakhstan). Silvestrichiloides berkarensis sp. nov. differs from the other species of this genus in the structure of antennal flagellum, apical palpomere of labial palp and ovipositor. Among species of the subgenus Kaplinilis Mendes, 1990, A. nigrostriatus sp. nov. belongs to a group of species characterized by numerous short chaetae on the ventral surface of the 5–7th palpomeres of the male maxillary palp and by the absence on the labial palp. This group includes two species: A. volgensis Kaplin, 1999 from Samara Region and A. smelyanskii Kaplin, 1999 from Orenbourg Region (both Russia). The new species differs from A. volgensis and A. smelyanskii in the length of the body and antenna, color of scales on the upper surface of the body, shape of the compound eye and paired ocellus, structure of the flagellum and apical palpomere of the male labial palp. The subgenus Machilanus Silvestri, 1934 is represented only by A. bitschi Wygodzinsky, 1962 from Afghanistan and A. perfectus sp. nov., which are characterized by numerous short chaetae on the ventral surface of the 2nd–7th palpomeres of the male maxillary palp. Allopsontus perfectus sp. nov. differs from A. bitschi in the shape of compound eyes, paired ocellus, structure of male labial palp and genitalia.Published online: 24th November 2021
