One new species, G. yunnanensis Hou, Yang ＆ Zhang, sp. nov., are described and illustrated. Three newly records from China, G. foersteri Meigen, 1938, G. nigricoma Lee ＆ Han, 2010 and G. olgae（Rohdendorf, 1927） are noted and illustrated too. Diagnoses of species examined and a key to 14 species of Gonia in China are provided.展开更多
