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): 363-374Abstract: 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.

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): 375-426Abstract: 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): 427-434Abstract: 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): 435-445Abstract: 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
Moctezuma Victor, Halffter Gonzalo, Lizardo ViridianaThe Phanaeus tridens species group (Coleoptera: Scarabaeoidea): a dung beetle group with genital morphological stasis but a changing ecological nicheActa Entomologica Musei Nationalis Pragae 61(2): 447-482Abstract: The Phanaeus tridens species group is revised and found to consist of twelve species: P. tridens Castelnau, 1840, P. moroni Arnaud, 2001 stat. rev., P. balthasari Arnaud, 2001 stat. rev., P. daphnis Harold, 1863, P. coeruleus Bates, 1887 stat. rev., P. herbeus Bates, 1887 stat. rev., P. substriolatus Balthasar, 1939 stat. rev., P. furiosus Bates, 1887, P. pseudofurcosus Balthasar, 1939 stat. rev., P. nimrod Harold, 1863, P. victoriae Moctezuma sp. nov., and P. eximius Bates, 1887. The majority of the name-bearing types of the group were revised. The neotype for P. tridens is suggested herein. The following junior subjective synonymies are recognized: P. frankenbergeri Balthasar, 1939 = P. tridens Castelnau, 1840, P. tricornis Olsoufieff, 1924 = P. herbeus Bates, 1887, and P. babori Balthasar, 1939 = P. nimrod Harold, 1863; while P. furcosus Felsche, 1901 = P. furiosus Bates, 1887 is recognized as a junior objective synonymy. The species within the P. tridens species group are diagnosed by the morphology of the pronotum and elytra, while the genital morphology of males is found to be homogeneous and uninformative for species delimitation. Most species within the group show a wide diversity of colouration (showing green, red, and blue chromatic phases). This probably led to taxonomical confusion by previous authors. Here, we present a new identification key, species distribution models. Habitus photographs and character illustrations for all the species within the group are provided. The climatic niches overlap widely in P. herbeus and P. daphnis, but the other species within the group show a reduced overlap in their climatic niches. Consequently, the P. tridens species group is proposed as a case of morphological stasis that might be explained by a trade-off between the evolution of pronotal structures and genitalia, while differences in the ecological niche might promote speciation.Published online: 18th December 2021
Šumpich Jan, Jagelka MartinLemonia batavorum sp. nov. from the Netherlands, an overlooked sibling of L. dumi (Lepidoptera: Brahmaeidae)Acta Entomologica Musei Nationalis Pragae 61(2): 483-494Abstract: Barcoding of Dutch specimens of Lemonia dumi (Linnaeus, 1761) (Lepidoptera:
Brahmaeidae) and a study of a large collection material of this species resulted in discovery of a new, hitherto undescribed species Lemonia batavorum sp. nov. Based on comparison with L. dumi, species level of L. batavorum sp. nov. is supported by the differences in its external appearance, diff erences in genitalia of both sexes and by 1.92% p-distance to L. dumi as the nearest neighbour. Photographs of specimens and genitalia of both sexes are given.Published online: 24th December 2021
Löbl Ivan, Hájek JiříScaphisomatini (Coleoptera: Staphylinidae: Scaphidiinae) from two biosphere reserves in eastern China, with descriptions of two new speciesActa Entomologica Musei Nationalis Pragae 61(2): 495-501Abstract: Members of the scaphidiine tribe Scaphisomatini collected recently in Tianmushan Biosphere Reserve (Zhejiang) and Wuyishan National Nature Reserve (part of Wuyishan Biosphere Reserve, Fujian), China, are studied. Two species, Scaphisoma krali Löbl, sp. nov. and Scaphisoma sekerkai Löbl, sp. nov., are described from Wuyishan. Baeocera franzi (Löbl, 1973) and Scaphisoma mutator Löbl, 2000 are recorded for the first time from Zhejiang province, and Scaphisoma binhanum (Pic, 1922) and Scaphoxium intermedium Löbl, 1984 are recorded for the first time from Fujian province.Published online: 30th December 2021
Lasoń Andrzej, Hájek Jiří, Jelínek JosefThe Nitidula carnaria complex, with description of a new species from Central Asia, and a key to world species of the genus (Coleoptera: Nitidulidae)Acta Entomologica Musei Nationalis Pragae 61(2): 503-516Abstract: The Nitidula carnaria complex is defined to comprise three Palaearctic species: the widely distributed Nitidula carnaria (Schaller, 1783), N. maculosa Fairmaire, 1866 occurring in the eremial of North Africa and the Middle East, and a newly described N. obenbergeri sp. nov. from northern China, Mongolia and neighbouring territories of Kazakhstan and Russia. First records are given for Nitidula carnaria from Georgia, Pakistan and Tajikistan; N. flavomaculata Rossi, 1790 from Azerbaijan, Kazakhstan and Kyrgyzstan; and for N. rufipes (Linnaeus, 1767) from Georgia, Kyrgyzstan, China (Shaanxi) and Russian Eastern Siberia. A lectotype of Nitidula latiplaga Solsky, 1876 is designated to fix its synonymy with N. flavomaculata Rossi, 1790 established by Jelínek & Audisio (2007). Habitus photographs of all species and an identification key are provided to facilitate identification of world Nitidula species. Finally, comments on the classification of four Neotropical taxa previously classified in the genus Nitidula are offered and the following changes are proposed: Mystrops bourgeoisi (Grouvelle, 1914), comb. nov., = M. gigas Kirejtshuk & Couturier, 2009, syn. nov.; and Catonura complanata (Germain, 1855), comb. nov., = Catonura ruficollis (Reitter, 1873), syn. nov., = Catonura rufithorax Reitter, 1883, syn. nov.

Bezděk JanRedefinition of Liroetis, with descriptions of two new species and an annotated list of species (Coleoptera: Chrysomelidae: Galerucinae)Acta Entomologica Musei Nationalis Pragae 61(2): 529-614Abstract: The genus Liroetis Weise, 1889 is redefined. The following new synonymies are established: Liroetis Weise, 1889 = Siemssenius Weise, 1922, syn. nov. = Pseudoliroetis Laboissière, 1929, syn. nov. = Zangia Chen, 1976, syn. nov. Consequently, the following new combinations are proposed: Liroetis coeruleus (Jiang, 1990) comb. nov.; Liroetis latispinus (Chen, 1976) comb. nov.; Liroetis nigricollis (Jiang, 1990) comb. nov.; Liroetis pallidulus (Jiang, 1990) comb. nov. (all from Zangia); Liroetis nigropictus (Fairmaire, 1889) comb. nov. (from Leptarthra); Liroetis cheni (Lee, 2016) comb. nov.; Liroetis elongatus (Kimoto, 1977) comb. nov.; Liroetis jeanvoinei (Laboissière, 1929) comb. nov.; Liroetis jungchani (Lee, 2016) comb. nov.; Liroetis liui (Lee, 2016) comb. nov.; Liroetis metallipennis (Chûjô, 1962) comb. nov.; Liroetis modestus (Weise, 1922) comb. nov.; Liroetis nigriceps (Laboissière, 1929) comb. nov.; Liroetis rufipennis (Chûjô, 1962) comb. nov.; Liroetis sulcipennis (Zhang & Yang, 2008) comb. nov.; Liroetis tsoui (Lee, 2016) comb. nov.; and Liroetis yuae (Lee, 2016) comb. nov. (all from Siemssenius). Two new species, Liroetis aurantiacus sp. nov., from continental South East Asia, and L. baolocanus sp. nov., from Vietnam, are described. A new substitute name, Liroetis medvedevi nom. nov., is proposed for L. nigricollis Medvedev, 2009 preoccupied by L. nigricollis (Jiang, 1990). The following new synonyms are established: Liroetis aeneipennis Weise, 1889 = L. tiemushannis Jiang, 1988, syn. nov.; Liroetis ephippiatus Laboissière, 1930 = Zangia signata Jiang, 1990, syn. nov. = L. postmaculatus Lopatin, 2004, syn. nov.; Liroetis leechi Jacoby, 1890 = L. verticalis Jiang, 1988, syn. nov.; Liroetis nigricollis (Jiang, 1990) = L. unicolor Zhang, Li & Yang, 2008, syn. nov.; Liroetis reitteri (Pic, 1934) = Pseudoliroetis trifasciata Jiang, 1992, syn. nov. The spelling of Liroetis tiemushannis Jiang, 1988 is fixed using the First Reviser Principle. Species of Liroetis are divided into five species-groups based on the combination of the following characters: presence/absence of border on anterior pronotal margin, width/length ratio of pronotum, structure of aedeagus, presence/absence of metatibial spur. The established groups are: the aeneipennis group, the aurantiacus group, the flavipennis group, the fulvipennis group, and the grandis group. The gender of Liroetis is masculine.Published online: 31st December 2021
Kment Petr, Salini S., Rédei Dávid, Rider DavidHalyomorpha halys fixed as the type species of the genus Halyomorpha (Hemiptera: Heteroptera: Pentatomidae)Acta Entomologica Musei Nationalis Pragae 61(2): 615-630Abstract: The genus Halyomorpha Mayr, 1864 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Cappaeini) was established based on a single species, Halys timorensis Westwood, 1837 (currently a junior subjective synonym of Halyomorpha picus (Fabricius, 1794)). The examination of the voucher specimens identified as Halyomorpha timorensis by Mayr, a syntype of Halys timorensis, and syntypes of Pentatoma halys Stål, 1855 revealed that: i) Halyomorpha timorensis (Westwood), stat. restit., must be reinstated as a valid species, and not considered as a junior subjective synonym of H. picus; ii) Mayr’s specimens belong to two different species, Halyomorpha halys (Stål) and H. picus. The problem of double misidentification of the type species of Halyomorpha is resolved by action of the first revising author(s) according to the Article 70.3 of the ICZN (1999): we fix here Pentatoma halys Stål, 1855 (= Halys timorensis sensu Mayr, nec Westwood) as the type species of Halyomorpha Mayr, 1864. A list of 36 valid species currently placed in Halyomorpha and their synonyms is compiled. We also issue a warning concerning the use of the citizen science approach for monitoring H. halys in Southeast Asia (which may also apply to other taxa): It is necessary to keep in mind that H. halys belongs to a group of habitually similar species (distributed from Pakistan and southern China to Indonesia and the Philippines) which cannot be identified with certainty without examination of their male genitalia; records merely based on observations or habitus photographs cannot be accepted as reliable.Published online: 31st December 2021
Damaška Albert František, Kouklík Ondřej, Vondráček DominikAbstracts of the Immature Beetles Meeting 2021 September 30–October 1, Prague, Czech RepublicActa Entomologica Musei Nationalis Pragae 61(2): 631-638Abstract: The Immature Beetles Meeting is a traditional two-day get-together of the international coleopterologist community, aimed mainly at beetle larvae. Despite the still ongoing COVID-19 pandemic situation, the meeting took place on 30 September and 1 October in Prague. This year, the special pandemic conditions forced us to bring the meeting partially to the online space to make the attendance possible for all colleagues from all over the world. Therefore, the meeting went on in a hybrid – both personal and online – form. The meeting took place, as traditional, at the Faculty of Science, Charles University, and was co-organized by the Department of Entomology, National Museum in Prague, the Crop Research Institute in Prague and the Czech Entomological Society. In total, 22 participants attended the meeting in person (see Fig. 1), while another 11 participants presented their talks in the online meeting form. Many other colleagues also attended the meeting online, but unfortunately, we are not able to provide the full list of these participants. Most of the attendees who arrived personally were from the Czech Republic and other European countries; in the online session, also colleagues from Asia and South America attended the meeting as they presented their talks or posters, but we are also aware of people from North America, or Australia, who appeared in the online space as well.
A total number of 14 contributions were presented, including 4 posters and 10 talks. The topics presented in the meeting covered a large spectrum of beetle families, including Cerambycidae, Coccinellidae, Hydrophilidae, Lucanidae, Lycidae, Phengodidae, Silphidae, Staphylinidae, Tenebrionidae and Trictenotomidae. Topics of general studies of beetle larvae were presented as well, including the modern methods of next-generation sequencing used in barcoding, biological sequence databases, and ecology. Moreover, the meeting continued as usual also in the evening after the session closure, in the informal “Larval Pub”, with discussions about beetles and life over a glass of the famous Czech beer.
Although the meeting was largely affected by the specific conditions caused by the epidemic situation, we are happy that the pandemic couldn’t prevent the coleopterists from meeting and sharing interesting research topics again. Hopefully, next years will allow all colleagues to come to Prague in person again, to meet fully with a lot of fascinating presentations and nice (not only) beetle talks during the evening pub gatherings.
