MALE GENITALIA – Ninth tergal lobes each with 4–7 setae; gonocoxite long and slender, basal mesal lobe very long, about 0.67 length of gonocoxite, separated from gonocoxite except basally, apex with cluster of strong spine-like setae; gonostylus very long and slender, nearly as long as gonocoxite; aedeagus ovoid, weakly sclerotised; paraproct with 3 apical teeth. LARVAE – Head large, broad; all setae with smooth branches; antenna long, setae 2,3-A branched, inserted before apex; comb of segment VIII with 16–30 small scales in anterior row and 8–15 longer scales in 2 or 3 posterior rows; siphon long, slightly tapered, index about 7, pecten comprised of 13–15 short triangular spines, seta 1-S inserted near mid-length, single or double, setae 1a-S and 2a-S absent; segment X with complete saddle, seta 1-X single, seta 2-X with 5 or 6 branches, setae 3-X with 1 very long and 2 very short branches, ventral brush (seta 4-X) with 10 or 11 long setae on grid and 2 short precratal setae.
