24. Vertex (a1) and mesosomal dorsum with strong, elongate setae. Peg sensilla of flagellum always strongly (b1) asymmetrical, never mushroom-shaped. Male genitalia (c1) without volsellar setae, but sometimes (c2) one pair of parameral setae placed in same area as volsellar setae (and probably are volsellar setae); parameres (d2: p) often elongate or sinuate (especially helpful in species with ambiguously placed parameral setae). Body <1mm in length; color always brownish with weak metallic luster (d1).

Perditorulus Hansson, 1996
