【形態 / Diagnosis】

• 体長1.77–2.03mm。体色は一様に黄褐色。♂の中脛節は通常で、拡がったり突起をもつことはない。♀の触角第11節（末端節）は拡大する。

【生態 / Bionomics】

• 幼虫はBombus derhamellus Kirby（ハチ目）の巣から得られている（Scott, 1920）。一方で成虫は訪花性を示し、各種の花から得られている（Audisio, 1993）。日本の個体群については生態の観察事例がないようだが、マルハナバチ属の巣を探すと、見つかるかもしれない。

【分布 / Distribution】

• Palaearctic Region: Europe, Iran, Turkey, West Siberia, Japan (Hokkaido, Honshu, Shikoku, Kyushu); Nearctic Region.
