Summary:The fauna and distribution of the blackflies in Gifu Prefecture were studied based on the collections of larvae and pupae from streams and of adults flying around the collectors at 111 sites in summer of 1994. A total of 18,481 blackflies, 16,576 larvae (89.7% in total number), 1,896 pupae (10.3%) and 9 adults (0.05%), were collected at 103 sites. All these blackflies were classified into 23 species of the genus Simulium Latreille and Prosimulium Roubaud. Three species, Simulium (Nevermannia) fontinale Radzivilovskaya 1948,S.(Gnus) sp. and S. sp. Y were newly recorded from Gifu Prefecture and the former was recorded for the first time from Japan. The most abundant species was S.(Simulium) kawamurae (26.6% in total number), followed by S.(S.) japonicum (23.3%), S.(Odagmia) aokii (13.6%), S.(Gnus) bidentatum (12.5%), S.(S.) suzukii (7.7%) and S.(N.) uchidai (6.1%). The most widely distributed species was S.(S.) japonicum (50 sites), followed by S.(N.) uchidai (49 sites), S.(O.) aokii (47 sites), S.(Gn.) bidentatum (46 sites), S.(S.) suzukii (46 sites), S.(S.) kawamurae (32 sites) and S.(Gomphostilbia) shogakii (29 sites).
