Abstract

Kieffer (1913) erected the genus Brillia, with Metriocnemus bifidus Kieffer, 1909 as the type species by original designation. To date, the genus comprises 15 valid species worldwide, including four species described from China. In this study, Brillia litangensis Liu, sp. nov., is described and illustrated as a male imago from Sichuan Province within the Oriental region of China. The new species inhabits high-altitude areas and shows strong cold tolerance. A key to the adult males of Brillia known from China is presented.
