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
