Abstract
Based on a recent collection of ichneumonids from Lao Cai Province, at an elevation above 1500 m above sea level, the genus Brachyzapus Gauld and Dubois, Citation2006 is reported from Vietnam for the first time and six new species are described: B. carinatus sp. nov., B. convexus sp. nov., B. duboisi sp. nov., B. fansipanensis sp. nov., B. hoanglienensis sp. nov. and B. politus sp. nov. Notes on distinguishing characters are provided and the new species are included in a tentative key to 12 species of Brachyzapus. Three species are formally transferred from Zabrachypus to Brachyzapus: B. atripedalis (Sheng, 2001), B. nitidus (Hao and Sheng, Citation2002) and B. nonareaeidos (Wang, 1997) are new combinations.
