Abdomen cylindrical, slightly expanded at posterior half, with six (male) or five (female) visible abdomeres. Legs relatively short, femora strongly enlarged, laterally flattened; metatibia about as long as metatarsus, first metatarsomere longer than next two combined.

Male genitalia. Tergite and sternite VIII subrectangular, truncated apically and strongly protruding laterally, with moderately long setae. Tegmen with parameres fused, sparsely clothed with setae apically; ringed part rounded, with lateral arms converged into a long median stem.
