Abstract

Four new species of fungus gnats, Ctenosciara japonica sp. nov., C. angustistylata sp. nov., C. meridiana sp. nov., and C. satoshii sp. nov., are described and figured. Ctenosciara hyalipennis (Meigen, 1804) and C. nudata Mohrig and Kozanek in Mohrig et al., 1992 are recorded for the first time from Japan. Ctenosciara insolita (Sasakawa, 1994) is newly recorded from Shikoku and Kyushu, Japan. Habitat preference and regional species diversity of this genus in the world are briefly discussed.
