Atomosini

Female Eumecosoma, copyright dguzman58.

Belongs within: Laphriinae.

The Atomosini are a group of small, sparsely haired robber flies.

Characters (from Wood 1981): Small rather bare species, less than 20 mm long, often with punctate mesonotum and abdomen. Antenna blunt apically; first flagellomere either with short bristle arising near middle of dorsal surface, or with stylus at apex. Palpus two-segmented. R₂₊₃ joining R₁ proximal to end of R₁, cell r₁ thus separated from wing margin; crossvein m-cu present, apex of cell bm closed by three veins. Postmetacoxal region with transverse heavily sclerotised bridge with posterodorsal margin V-shaped. Anatergite with bristly pile.
