南西諸島の沖縄島、宮古島、石垣島及び西表島から記録されている。主に枯れ枝から得られるが、特にモクマオウの枝からの採集例が多い。本属の種はどれもよく似るが、本種の尾管は太く幅と長さがほぼ等しい。本種の第８腹節背板の第2中間刺毛刺毛(IS2)＊は短い。食菌性。

This species has been recorded from Okinawa Is., Miyako Is., Ishigaki Is. and Iriomote Is. in the Ryukyu Islands. It is mainly obtained from dead branches, but is frequently collected from the branches of Casuarina equisetifolia. All congeners are very similar from one another, but the tube of this species is thicker and almost equal in width and length. The IS2＊ setae on the tergite VIII are reduced. Fungus-feeder.
＊The IS (intermediate setae) are short setae located between two pairs of prominent setae on the posterior margin of the tergite VIII. In this genus, there are two IS, the inner one is called IS1 and the outer one is called IS2.
