SUMMARY
Adults resemble Chaetosa punctipes in being small, grey and pale legged, but the single sternopleural bristle, lack of pointed tip to the third antennal segment and presence of a bright orange frontal stripe should serve to distinguish it. The male front legs are distinctive with a swelling on the underside of the femora that fits into a series of depressions on the tibia. Anderson (1974)[1] reviews the Northern European members of this genus which all have similar modifications to the front legs. Wing length: ♂ 4.7 - 5.0 - 5.2 mm (2); ♀ 4.4 - 4.6 - 5.0 mm (4).
