A new genus and two new species of Swordtail Crickets (Orthoptera: Trigonidiidae; Trigonidiinae) from China

摘要

Here we report two new species of the swordtail crickets (Orthoptera: Trigonidiidae; Trigonidiinae) from Yunnan and Guangxi Province, China. One species (Trigonidium rubrumoculus sp. nov.) belongs to the genus Trigonidium, and we describe a new genus for the other species (Polycomus gen. nov., Polycomus exspiravit sp. nov.). The new genus resembles Amusurgus Brunner von Wattenwyl, 1893 in appearance but differs in the structure of the male genitalia. Descriptions, illustrations, and distributions of these new species are provided.
