Three New Species of the Genus Leptogenys Roger, 1861 (Hymenoptera: Formicidae) from China, with an Updated Key to the Known Chinese Species

Leptogenys Roger, 1861 is the most diverse genus of the ant subfamily Ponerinae and primarily distributed in tropical and subtropical regions, especially in the Oriental realm. Taxonomic study of Leptogenys has been advancing with new species frequently discovered. In this paper three new Leptogenys species from South China are described based on morphological examination of workers: L. qini sp. nov. (Guangxi), L. scabra sp. nov. (Guangxi), and L. sunyatseni sp. nov. (Yunnan). Biogeographic information of these three new species and an updated key to currently known Chinese species are also provided.
