Abstract

Eight species of the genus Nephrotoma were previously known to occur in Xizang Autonomous Region. Here, three species are added to the fauna of Xizang. Among them two species, N. beibengensis sp. nov. and N. hanae sp. nov. are described and illustrated as new to science, and one species, N. evittata Alexander, 1935 is recorded from Xizang for the first time. The following four species are redescribed: N. claviformis Yang & Yang, 1987, N. didyma Yang & Yang, 1987, N. nigrohalterata Edwards, 1928, and N. xizangensis Yang & Yang, 1987. A key to the species of Nephrotoma from Xizang is presented.
