A review of the genus Tetragonoderus dejean (Coleoptera: Carabidae: Cyclosomini) in China

Abstract

Based on adult structural features, Chinese species of the genus Tetragonoderus Dejean are taxonomically treated. Four species are recognized in total. Of these, T. microthorax sp. n. (type locality: Jinghong, Yunnan Province, China) is described and illustrated. Two species, T. rhombophorus Schmidt- Göbel and T. fimbriatus (Bates), are newly recorded from China. Tetragonoderus quadrisignatus (Quens) which was originally known in Hongkong is reported from Guangdong and Hainan Provinces for the first time. A key to Chinese species of the genus is also provided.
