Abstract
Investigations were carried out on the fauna and distributions of black-flies in Kyushu in 1971-1974. A total of 2,072 pupae and 2,759 larvae were collected from 144 sites in 12 districts. Eighteen species and 1 subspecies were found, of which Simulium (Eusimulium) aureohirtum, S. (E.) sasai, S. (E.) subcostatum koshikiense, S. (E.) sp., S. (Gomphostilbia) ogatai and S. (Gnus) daisense were recorded for the first time from Kyushu. This brought the total number of Simuliidae in Kyushu to 25. The most abundant and widely distributed species are : S. (G.) bidentatum, S. (Simulium) arakawae, S. (Odagmia) aokii, S. (E.) uchidai, making up about 70% of the total number of specimens collected. Notes on geographical and vertical distributions of 19 taxa of black-flies in Kyushu were given.
