Abstract: Two new species of predominantly Australasian genus Austrelatus Shaverdo et al., 2023 are described and illustrated: Austrelatus mirai sp. nov. from Selangor State in Peninsular Malaysia is similar in habitus to the South Indian species A. boukali (Hendrich & Balke, 1998) and A. davidi (Wewalka, 2017); however, the shape of the male genitalia suggests that it is closely related to Austrelatus species from Kalimantan. Austrelatus riberai sp. nov. from Shan State in Myanmar is most similar to Sino-Japanese A. parallelus (Zimmermann, 1920). Findings of Austrelatus species in continental Southeast Asia fill the gap in the distribution area of the genus between India, China and Japan on one side, and the Sunda Islands on the other side.Published online: 1st October 2024
Yamane Seiki, Hosoishi Shingo, Ito FuminoriTaxonomic study on the queens of the Japanese ponerine genera, with a redescription of Ectomomyrmex horni restituted as a valid species (Hymenoptera: Formicidae)Acta Entomologica Musei Nationalis Pragae 64(2): 249-267Abstract: Queen ants of the Japanese ponerine genera are described, with the first key to the Japanese genera based on the queen caste. Important queen characters are enumerated and caste differences are discussed for each genus. Physical and behavioral aspects of functional queens (alate/dealate queen, ergatoid, and gamergate) in the Japanese ponerines are briefly discussed. Ectomomyrmex horni (Forel, 1913), stat. restit., is resurrected from synonymy with Ectomomyrmex javanus Mayr, 1867. A redescription of E. horni is presented based on Japanese and Taiwanese specimens.Published online: 1st October 2024
Cho Hee-Wook, Kim Kang-RaeA new species of Autocrates (Coleoptera: Trictenotomidae) revealed by DNA barcoding and morphological evidenceActa Entomologica Musei Nationalis Pragae 64(2): 269-276Abstract: Autocrates soni sp. nov. is described from Vietnam based on morphological and molecular evidence. This beetle is characterised by reddish-brown pubescence on its ventral side and much shorter setae on its femora compared to the closely related species Autocrates vitalisi Vuillet, 1912. The validity of this new species is strongly supported by DNA barcode data from all known species of the genus Autocrates.Published online: 31st October 2024

Anthomyza gilviventris in Palaearctic Region: integrative taxonomy, variability and habitat associations of North European population (Diptera: Anthomyzidae)Acta Entomologica Musei Nationalis Pragae 64(2): 277-291Abstract: Anthomyza gilviventris Roháček & Barber, 2016, hitherto known only from the Nearctic Region, is recorded from the Palaearctic Region (NE Sweden) for the first time. Specimens from the Swedish population have been compared with those of A. gilviventris from Canada and the USA and those of A. tschirnhausi Roháček, 2009 from the Kamchatka Peninsula (Far East of Russia). Both morphological and molecular analyses (BI and RAxML, based on seven DNA markers: 12S, 16S, 28S, COI, COII, CytB, ITS2) confirmed that the Swedish specimens belong to A. gilviventris. Because no specimen of A. tschirnhausi has been available for molecular study, the most diagnostic morphological characters used for separation of this species from A. gilviventris have been re-evaluated with respect to Swedish specimens, and their variability discussed. However, these differences, although stable, are relatively small and, consequently, the possibility that they fall within the limits of a single variable species has not been entirely eliminated. New biological information (habitat and host-plant associations) on the Swedish population of A. gilviventris is presented.Published online: 31st October 2024
Bi Wen-Xuan, Chen Chang-ChinFirst record of the genus Falsorsidis from China, with description of one new species and transfer of the genus to the tribe Lamiini (Coleoptera: Cerambycidae)Acta Entomologica Musei Nationalis Pragae 64(2): 293-297Abstract: A little-known genus Falsorsidis Breuning, 1959 (Coleoptera: Cerambycidae:
Lamiinae), so far known only from Vietnam, is newly recorded from China upon the discoveries of its type and until now the only known species, F. griseofasciatus (Pic, 1926), from Guangxi, and F. lichaoi sp. nov. from Yunnan. The genus is proposed to be transferred from the tribe Desmiphorini to Lamiini and is considered to be closest to the Oriental genus Granulorsidis Breuning, 1980. Description and illustrations of the habitus, endophallic structure and major diagnostic features for the involved taxa are provided.Published online: 24th November 2024
Li Di, Aspöck Ulrike, Aspöck Horst, Liu Xingyue Two new species of the beaded lacewing genus Asadeteva (Neuroptera: Berothidae) from ThailandActa Entomologica Musei Nationalis Pragae 64(2): 299-305Abstract: Asadeteva U. Aspöck & H. Aspöck, 1981 (Neuroptera, Berothidae), has been
traditionally considered a Palearctic faunal element. Asadeteva was originally described from Afghanistan and Pakistan, while recent report has extended its known range into the Oriental Region. Herein, we report two new species of Asadeteva from Thailand, namely Asadeteva christophi U. Aspöck & H. Aspöck sp. nov. and Asadeteva thailandica sp. nov. This discovery highlights the presence and diversity of this genus in the Oriental Region. A distribution map and a revised key to the species of Asadeteva are also provided.Published online: 24th November 2024
Montoya Augusto LeónDescription of two new species of Lycopale (Diptera: Syrphidae) from the northwestern Tropical Andes hotspot, with the redescription of Lycopale magnificaActa Entomologica Musei Nationalis Pragae 64(2): 307-325Abstract: Lycopale Hull, 1944 is a small Neotropical flower fly genus (Syrphidae: Eristalinae: Eristalini: Helophilina) with six described species. Recent surveys in the Colombian and Ecuadorian Andean Forest and Paramo ecosystems revealed the discovery of two species new to science: Lycopale mendozai sp. nov. and Lycopale radioheadi sp. nov. Simultaneously, the species Lycopale magnifica (Bigot, 1880) was rediscovered and is redescribed here, nearly a century after its original description, including photographs of its habitus and illustrations of the male genitalia. A new key is proposed, including illustrations of thoracic and abdominal patterns of all known species to distinguish them from the new taxa. Distributional patterns are illustrated and discussed. Mitochondrial cytochrome c oxidase subunit I (COI) sequences are provided for the three species, L. magnifica, L. mendozai sp. nov., and L. radioheadi sp. nov. The discovery of these two new species suggests that the Tropical Andes diversity of flower flies is still underestimated and many more unnamed species remain to be discovered and described from this biodiversity hotspot.Published online: 24th November 2024
Gierlasiński Grzegorz, Magnien Philippe, Kepel Andrzej, Wiśniewski Konrad, Lange AleksandraKojderus maximus, a new genus and species of Tessaratomidae (Hemiptera: Heteroptera), the first Natalicolinae from MadagascarActa Entomologica Musei Nationalis Pragae 64(2): 327-335Abstract: Kojderus Magnien & Gierlasiński gen. nov., with a single species, Kojderus maximus Gierlasiński & Magnien sp. nov. (Hemiptera: Heteroptera: Tessaratomidae), is described, being the first representative of the subfamily Natalicolinae in Madagascar. The new taxon is diagnosed and described and photographic images of habitus and genital structures of both sexes are provided. It was collected in the Ivohiboro rainforest in south-central Madagascar, which is also briefly described. An updated key to the genera of Natalicolinae is provided.Published online: 1st December 2024
Audisio Paolo, Jelínek Josef, Sabatelli Simone, Hájek Jiří, Liu MeikeA new Aristogethes pollen beetle from Oman, with a commented and updated checklist of the species (Coleoptera: Nitidulidae)Acta Entomologica Musei Nationalis Pragae 64(2): 337-344Abstract: An unexpected new species of the genus Aristogethes Audisio & Cline, 2009, A. pelikani sp. nov., is described from southern Oman (Arabian Peninsula). This new species appears to be morphologically rather closely related to a couple of species known from southern Africa (northern South Africa, Botswana and southern Namibia): A. eremita (Audisio, Kirk-Spriggs & Kirejtshuk, 1998) and especially A. rufofuscus (Audisio, Kirk-Spriggs & Kirejtshuk, 1998), with which it shares several morphological traits and some interesting eco-ethological adaptations; these three species are, in fact, all specialized to live in stony sub-desert environments, with phenology mostly in August-September in both areas (southern Africa and southern Arabian Peninsula); they are also all associated for larval development with sub-desertic Malvaceae: Sterculioideae of the genus Hermannia L. The new species is otherwise easily distinguished from its two southern African relatives by the peculiarly shining and coarsely punctuated elytral surface, smaller average body sizes, narrower and at base much more acutely toothed tarsal claws, and the different male and female genitalia, more like those of Aristogethes rufofuscus. The larval hostplant of the new species is represented by Hermannia (Mahernia) paniculata Franch., a small eremic southern Arabian and Northeast African species, typically growing at low altitude in stony sub-desert habitats, close to the sea. An updated and commented checklist to known species of Aristogethes is presented.Published online: 12th December 2024

Carapezza Attilio, Kment PetrShibhonia buxanthi, a new genus and species of dorsally punctate Mirini from the island of Socotra (Hemiptera: Heteroptera: Miridae)Acta Entomologica Musei Nationalis Pragae 64(2): 355-363Abstract: Shibhonia buxanthi gen. & sp. nov., living on Buxus hildebrandtii (senior synonym of Buxanthus pedicellatus) (Buxales: Buxaceae) on Socotra Island (Yemen) is described and illustrated. The new taxon is the sixth species of Miridae recorded from the island and the first endemic genus of this family. Due to the complex of its characters, it belongs to the group of dorsally punctate genera of the tribe Mirini. Inside this group it shows some superficial similarities (especially the colouration and body shape) with the genera Capsus Fabricius, 1803, Chilocrates Horváth, 1889 and Koreocoris Cho & Kwon, 2008, but it is readily distinguished from both by relevant morphological differences, particularly in the structure of male and female genitalia.Published online: 26th December 2024
Matocq Armand, Aukema Berend, Genson Guénaëlle, de Knijff Peter, Pierre Éric, Streito Jean-ClaudeContribution to the study of the genus Dicyphus: the case of D. bolivari and D. tamaninii (Hemiptera: Heteroptera: Miridae)Acta Entomologica Musei Nationalis Pragae 64(2): 365-381Abstract: The genus Dicyphus Fieber, 1858 (Miridae: Bryocorinae: Dicyphini) comprises small plant bugs well known for their zoophytophagous diet and predatory activity, making them useful in biological control. Despite their importance in plant protection, many species remain difficult or impossible to identify. This is the case of both species Dicyphus (Dicyphus) bolivari Lindberg, 1934 and Dicyphus (Dicyphus) tamaninii Wagner, 1951, commonly found in vegetable crops in Western Europe. We have conducted a taxonomic study integrating morphological (including male and female genitalia), molecular, biogeographical, and biological data. The following new synonymy is proposed: Dicyphus bolivari Lindberg, 1934 = Dicyphus tamaninii Wagner, 1951, syn. nov. The synonymies established by Sanchez & Cassis (2018), Dicyphus bolivari Lindberg, 1934 = Dicyphus bolivari atlanticus Wagner, 1951 = D. marocca-
nus Wagner, 1951, are confirmed. Dicyphus bolivari is compared to closely related species. The following country records are added to D. bolivari range: Channel Islands: Guernsey, Italy: Sardinia, Monaco, Asian part of Turkey and Cyprus.Published online: 26th December 2024
López Guilherme E. L., Schwertner Cristiano F.A new species of Pelidnocoris (Hemiptera: Heteroptera: Pentatomidae) from the Brazilian Atlantic ForestActa Entomologica Musei Nationalis Pragae 64(2): 383-395Abstract: In this work a new species, Pelidnocoris paradisicola sp. nov., of the genus Pelidnocoris Stål, 1868 (Hemiptera: Heteroptera: Pentatomoidea: Pentatomidae: Discocephalinae) is described from the southeastern Brazilian state of Minas Gerais. An up-to-date diagnosis of the genus and its species is provided, comparing them with similar-looking Discocephalini genera. This is the first record of the genus for the Atlantic Forest, in southeastern South America, and increases the number of species in Pelidnocoris to four. The other species of Pelidnocoris are distributed from southern North America to northern South America, with records from Mexico, Colombia, Costa Rica, Panama, and northern Brazil. Photographs from the citizen science platform iNaturalist indicate the genus is also distributed in the state of São Paulo, Brazil, as well as in Belize, Ecuador and Peru, all representing new records. An identification key to the species of the genus is included, based on characters of general morphology and external male genitalia. Identification of the genus and its species from photographs in online repositories and databases is addressed.

Yasunaga TomohideReassessment of characters of the ‘Orientomiris-group’, with descriptions of three new genera and eight new species of the tribe Mirini from the Oriental Region (Hemiptera: Heteroptera: Miridae)Acta Entomologica Musei Nationalis Pragae 64(2): 397-426Abstract: Possession of stridulatory devices (serrated forewing edge and metafemoral plectra) is suggested as a useful taxonomic character for classification of the complex group comprising Creontiades Distant, 1883, Megacoelum Fieber, 1858, Orientomiris Yasunaga, 1997 and an additional superficially similar taxon which is provisionally called the Orientomiris-group. Three new genera, Muttiocapsus gen. nov., Nythomiris gen. nov. and Sakaeratiella gen. nov., are proposed to accommodate two unique undescribed species from the Oriental Region and a known taxon, Adelphocorisella adelphocoroides Yasunaga, Shishido & Yamada, 2016 from Thailand, respectively. Accordingly, a new combination, Sakaeratiella adelphocoroides comb. nov., is established. Four new species of Orientomiris Yasunaga, 1997 from Peninsular Malaysia, Taiwan and Thailand are also described.Published online: 26th December 2024
Hovorka Tomáš, Boudreault Caroline, van Achterberg Kees, Fernandez-Triana Jose L.Description of five new species of the rare genus Buluka (Hymenoptera: Braconidae: Microgastrinae) with an updated key to the world speciesActa Entomologica Musei Nationalis Pragae 64(2): 427-453Abstract: Five new species of the rare genus Buluka de Saeger, 1948 (Hymenoptera:
Braconidae: Microgastrinae), B. buntikae Hovorka & Fernández-Triana sp. nov. (from
Thailand), B. frederiquebakkerae Hovorka & Fernández-Triana sp. nov. (from Indonesia), B. janaorlikovae Hovorka & Fernández-Triana sp. nov. (from Vietnam), B. longi Hovorka & Fernández-Triana sp. nov. (from Vietnam), and B. petrjanstai Hovorka & Fernández-Triana sp. nov (from Thailand), are described in this paper. The newly described species increase the total number of species in this genus to 16 (i.e., by 45%). Additionally, Buluka achterbergi Austin, 1989 is reported from Thailand for the first time and B. straeleni de Saeger, 1948 from the Republic of the Congo for the first time.

Leschen Richard A. B., Chen Yandong, Harmer Aaron M. T.Revision of flightless New Zealand Picrotini (Coleoptera: Cryptophagidae): phylogeny of Thortus, eye reduction, and rarityActa Entomologica Musei Nationalis Pragae 64(2): 455-500Abstract: The apterous New Zealand genera Picrotus Sharp, 1886 and Thortus Broun, 1893 are revised to include two species and 13 species, respectively, with 12 new species: Picrotus wairarapa sp. nov., Thortus bullerensis sp. nov., T. crowsoni sp. nov., T. helmorei sp. nov., T. latus sp. nov., T. lobatus sp. nov., T. luscus sp. nov., T. michauxi sp. nov., T. parallelus sp. nov., T. simplex sp. nov., T. sulcatus sp. nov. and T. tioripatea sp. nov. One species previously thought to be a member of Picrotus is transferred to a new genus: Callichrotus gimmeli gen. & sp. nov. The largest species, T. michauxi, is endemic to the subantarctic islands while the rest are mainland. Four species of Thortus have eyes consisting of a single ommatidium. We determined the origin of microphthalmy and attempt to reconstruct the biogeography of Thortus with a morphological cladistic analysis that included Callichrotus and Picrotus as outgroups. Thortus michauxi was sister to remaining species with largely unresolved relationships and included two monophyletic clusters. Thortus amoenus (Broun, 1912), T. lobatus, and T. sulcatus formed a group based on the presence of a complete parasutural striae, and within it, the latter two species have parameres with posterior membranous extensions, which supports them as sister species. In some trees, T. bullerensis, T. parallelus, and T. ovalis are supported by a narrowly constricted frons, a character that is variable within the genus. Microphthalmy evolved multiple times in Thortus. Eye reduction in other New Zealand beetles is reviewed. Based on number of collection events and specimen counts, most species would be considered as rare, with six newly described species known from single locations, three species of which are known from singletons. Despite classed as rare, it is likely that most species may be protected from extinction because they live in reserves or national parks.Published online: 26th December 2024
