MALE GENITALIA – Ninth tergal lobes prominent, each with 9–15 setae; basal mesal lobe very long, 0.67‒0.90 length of gonocoxite, largely or partially separated from gonocoxite, apex setose; gonostylus very long and slender, nearly as long as gonocoxite; aedeagus relatively large and strongly sclerotised; paraproct with 7 or 8 apical teeth, cercal setae numerous. LARVAE – Head large, broad; antenna moderately long, usually not shorter than head, seta 1-S inserted well beyond mid-length of shaft, setae 2,3-A single, inserted slightly before apex; comb of segment VIII with approximately 90 scales in triangular patch; siphon long, slightly tapered, index 5.0‒5.4, pecten comprised of 7–11 hair-like spines borne on proximal 0.5 or less of siphon, seta 1-S inserted at base of siphon, single or double, setae 1a-S and 2a-S absent; segment X with complete saddle, seta 1-X branched, seta 2-X with 9‒11 branches, setae 3-X very long, single, ventral brush (seta 4-X) with 12 or 14 long setae on grid, no precratal setae.
