Description of Prosimulium sarurense n. sp. from Japan (Diptera, Simuliidae)

Abstract

Prosimulium sarurense n. sp. is described based on the specimens taken from the streams of Saruru river, the southern region of Hidaka range, Hokkaido. The species seems to be closely related to Prosimulium yezoense Shiraki, 1935,but differs from it in the structure of genitalia in both sexes and pupal respiratory organs.
