Head wider than long, with one pair of prominent setae on genae; postocular setae shorter than cheek setae; maxillary stylets retracted to eyes, about one-third of head width apart, maxillary bridge well developed. Antennae 8-segmented; segment III with one sense cone, IV with 3 sense cones. Pronotum transverse, notopleural sutures complete; antero-marginal, antero-angular, midlateral and postero-angular setae variable, usually short. Prosternal basantra absent; ferna wider than long; mesopresternum of two lateral triangles; metathoracic sterno-pleural sutures long. Metanotum reticulate, median setae small, without anteromedian minor setae. Fore tarsal tooth small, hook-shaped at inner apex of tarsus. Fore wing with 3 to 8 duplicated cilia; sub-basal setae short and stout. Pelta broadly triangular with truncate apex; tergites II–VII each with 2 pairs of sigmoid wing-retaining setae, female with group of 6 to 24 short exceptionally stout and laterally directed, discal setae laterally; two pairs of short, stout and acute lateral posteromarginal setae, each arising from a small tubercle; tergite IX setae S1 & S2 capitate, shorter than tube; tube with anal setae as long as or longer than tube; sternites III–VII with paired lateral areas of specialised reticulation. Male with setae S2 on tergite IX as long as or longer than S1; sternite VIII without pore plate.
