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
