New records and checklist of chilocorini (Coleoptera: Coccinellidae) from China

Abstract

Background China is one of the countries with the greatest species diversity of Chilocorini (Coleoptera: Coccinellidae), including nearly forty-five percent of the known genera and fourteen percent of all described species in this tribe. Recently, we discovered three species previously not recorded in China. New information In this study, three species Priscibrumus uropygialis (Mulsant, 1853), Priscibrumus disjunctus Canepari, 1997 and Brumus octosignatus (Gebler, 1830) are documented for the first time in China. Brumus octosignatus is the first member of the genus Brumus Mulsant, 1850 recorded in China. Detailed descriptions, illustrations and distributions of these three species are provided. A checklist of Chinese Chilocorini is also given.
