静岡から記載されたやや稀な種である。その後も東京都や神奈川県の常緑広葉樹林から記録され、枯れ木に穿たれたカミキリムシやキクイムシなどの孔道から稀に発見されることが多い。A. spinurusによく似るが、第8腹節背板のIS2刺毛（A. casuarinaの解説を参照）が発達しないことで区別できる。食菌性。

This species is a rather rare species described from Shizuoka. Since then, it has been recorded in evergreen broad-leaved forests in Tokyo and Kanagawa prefectures, and is rarely found in the galleries on the dead branches drilled by the certain insects, such as cerambycid and scolytid beetles. It closely resembles A. spinurus, but can be distinguished by the IS2 setae (see the comment on A. casuarina) on the tergite VIII reduced. Fungus-feeder.
