This species has been recorded from Honshu (Kanagawa Pref.), the Izu Islands and the Ryukyu Islands, and is likely widely distributed south of the Kanto region. It inhabits dead leaves and branches. This genus can be distinguished from closely related genera by the presence of two pairs of wing-retaining setae on the abdominal tergite VIII. Fungus-feeder.
