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
