Descriptions of all stages of female Simulium (Simulium) cognatum sp. nov., collected from a stream m Yadong County, Tibet, China, are herewith given with illustrations. This species is assigned to the variegatum-group, Simulium subgenus and is closely related to S. ( S. ) triangustum An, Guo and Xu, 1995, S. ( S. ) yadongense Deng and Chen, 1993, S. (S.) taiwanicum Takaoka, 1979, S. (S.) shanxiense Cai and An 2003 and S. (S.) immortalis Cai and An, 2003. However, the new species may be clearly distinguished from them by the structure of gonapophyses, genital fork, genital plate, paraproct, pupal gill filaments and larval postgenal cleft. All the specimens are kept in the Medical Entomology Collection Gallery, Beijing Institute of Microbiology and Epidemiology.
