Abstract: Japanese species of the genera Stethorus Weise, 1885 and Parastethorus Pang & Mao, 1975 (Coleoptera: Coccinellidae: Coccinellinae) were reviewed, recognizing seven species of the former and one species of the latter genus. Two new species are described: Stethorus (Allostethorus) takakoae sp. nov. from Hokkaido and Parastethorus pinicola sp. nov. from Honshu, Kyushu, and the Ryukyu Islands. Stethorus (Stethorus) japonicus Kamiya, 1959, syn. nov., and S. (S.) aptus tsutsuii Nakane & Araki, 1959, syn. nov., are synonymized with S. (S.) siphonulus Kapur, 1948. Stethorus (A.) chengi Sasaji, 1968 and S. (A.) parapauperculus Pang, 1966 are newly recorded from Japan (both from the Ryukyu Islands). The holotype specimens of S. (A.) chengi Sasaji, 1968, S. (A.) emarginatus Miyatake, 1966, S. (A.) yezoensis Miyatake, 1966, S. (S.) aptus tsutsuii Nakane & Araki, 1959, and S. (S.) japonicus Kamiya, 1959 were examined, and all species are redescribed or diagnosed. Additionally, diagnostic characters are illustrated together with distribution maps. The larvae and pupae of the new species P. pinicola sp. nov. are also illustrated.Published online: 7th November 2025
Tanaka Hirotaka, Le Hoang KhacA new species of the genus Ferrisia (Hemiptera: Coccomorpha: Pseudococcidae) from southern VietnamActa Entomologica Musei Nationalis Pragae 65(2): 293-300Abstract: In this paper, a new species, Ferrisia san Tanaka, sp. nov. (Hemiptera: Sternorrhyncha: Coccomorpha: Pseudococcidae), is described and illustrated based on the morphology of adult female specimens collected on cassava, Manihot esculenta (Euphorbiaceae), from Ho Chi Minh City and Dong Nai province in southern Vietnam. This is the second species of Ferrisia Fullaway, 1923, a genus native to the Americas, to be found in Vietnam. The adult female of this new species has a combination of morphological features distinct from those of named species of Ferrisia: the small type of the ventral oral-collar tubular ducts is present anterior to the multilocular disc pore rows as well as on the ventral submarginal area, but never forms marginal clusters; the large type of the ventral oral-collar ducts is confined to the posterior abdomen; and the dorsal enlarged tubular ducts are sometimes associated with one or two discoidal pores, which are mostly on the outermost edges of the sclerotized area of the ducts. An updated key to species of Ferrisia is provided, and the potential risks of this new species for the cultivation of cassava in Vietnam, and its implications for international quarantine are discussed.Published online: 10th December 2025
Hovorka Tomáš, Boudreault Caroline, Fernandez-Triana JoseFirst African and Malagasy records of Miropotes (Hymenoptera: Braconidae: Microgastrinae), with three new species and a revised key to all known speciesActa Entomologica Musei Nationalis Pragae 65(2): 301-312Abstract: Three new species of the rarely collected genus Miropotes Nixon, 1965 (Hymeno-
ptera: Braconidae: Microgastrinae) are described: Miropotes klaseriensis sp. nov. from South Africa, and Miropotes perditohabitatus sp. nov. and Miropotes malagasifragilis sp. nov. from Madagascar. These are the first confirmed records of the genus from sub-Saharan Africa and Madagascar, significantly expanding the known distribution range of Miropotes within the Afrotropical Region beyond the single species previously documented in the Arabian Peninsula. An updated key to all currently 18 recognized species of Miropotes including those in the Oriental and Australasian Regions is also provided.Published online: 10th December 2025
Urcola Juan Ignacio, Urcola Matias Ricardo, Roig-Juñent Sergio, Michat Mariano CruzImmature stages of the tiger beetle Cylindera (Plectographa) apiata apiata (Coleoptera: Cicindelidae) and analysis of primary chaetotaxyActa Entomologica Musei Nationalis Pragae 65(2): 313-332Abstract: The larval instars and pupa of Cylindera (Plectographa) apiata apiata (Dejean, 1825) are redescribed and illustrated, including morphometric and chaetotaxic characters. The larval ground pattern for the chaetotaxic characters is presented, based on instar I larva of C. apiata apiata. For chaetotaxic homologization, comparisons with other adephagan families were performed. The primary chaetotaxy of cicindelid larvae is very similar to that described for Carabidae, and both are distinguished from the aquatic adephagan families by the presence of seta TR8 and pore COb; additionally, they are characterized by the presence of long setae on the apices of the antenna (setae AN4–6) and galea (MX8–9). On the other hand, Cicindelidae differ from Carabidae in the presence of setae PA20–22 on the parietal and setae FE7–8 on the femur, the absence of pores COc–e on the coxa, and by having a single seta on the pretarsus, a condition unique to Cicindelidae. The habitat where both adults and larvae of C. apiata apiata were collected is described and illustrated, and the phenology of the species is briefly discussed.Published online: 10th December 2025
Szczepański Wojciech T., Dobosz Roland, Kerimova Ilhama G.A new species of Dasypogon (Diptera: Asilidae) from Azerbaijan with notes on its biologyActa Entomologica Musei Nationalis Pragae 65(2): 333-340Abstract: Dasypogon kerimovae Szczepański & Dobosz sp. nov. (Diptera: Asilidae) is diagnosed and described from Azerbaijan. The species is readily distinguished by the male terminalia and unique combination of characters of females, which exhibit dark coloration resembling that of males, including smoky black wings, black legs and predominantly black setae. Photographic documentation of the habitus and the male and female genital structures is included. Observations concerning habitat preferences, flight activity, and biological interactions are discussed, with particular emphasis on ecological plasticity, mimicry, and trophic relationships.Published online: 10th December 2025
Jiang Ri-Xin, Long Jian-Kun, Chang Zhi-Min, Chen Xiang-Sheng, Yang LinDescription of the mature larva and pupa of Menephilus medius (Coleoptera: Tenebrionidae)Acta Entomologica Musei Nationalis Pragae 65(2): 341-348Abstract: The larva and pupa of Menephilus medius Marseul, 1876 (Coleoptera: Tenebrionidae: Stenochiinae: Cnodalonini) from southern China are associated with the adults by rearing in lab. The morphological characteristics of the mature larva and pupa of this species are described and illustrated in detail for the first time and compared with the immature stages of Menephilus cylindricus Herbst, 1784.Published online: 10th December 2025
Kovacevic Maja, Kasalo NikoDeconstructing the Australian Tetrix (Orthoptera: Tetrigidae): three new genera and a new species, Cyphotettix elluraeActa Entomologica Musei Nationalis Pragae 65(2): 349-364Abstract: Until now, the Australian fauna of Tetriginae has been represented predominantly by the genera Paratettix Bolívar, 1887 and Tetrix Latreille, 1802, with the latter mostly consisting of apterous species. The Australian members of these genera show remarkable morphological diversity, which prompted us to reexamine the relationships between them using cladistic analysis based on morphological characters of head and thorax. We have found that the Australian Tetrix spp. are easily separable into three distinct genera: Captivus gen. nov., Custodia gen. nov., and Enattor gen. nov. Additionally, we describe a new species of the Tetriginae genus Cyphotettix Rehn, 1952, C. ellurae sp. nov. We provide an identification key to the Australian Tetriginae genera and hypothesize that the apterous species are related to Tetrix collina Rehn, 1952.Published online: 10th December 2025
