Distinguishing features

Both sexes fully winged. Body and legs dark brown with tarsi yellow, antennal segments III–VI and sometimes base of VII yellow. Antennae 8-segmented, III with one sensorium, IV with three sensoria, VIII broad at base. Head longer than wide; cheeks with one pair of stout setae in basal third; maxillary stylets retracted at least to postocular setae; postocular setae no larger than minor setae. Pronotum with three pairs of capitate major setae, anteromarginals and midlaterals usually no larger than discals. Prosternal basantra not developed; mesopresternum reduced to two small lateral triangles. Fore tarsus with inner apex slightly recurved forming a small tooth in female; large male with fore tarsal tooth massive and femora swollen. Fore wing parallel sided, with 6–9 duplicated cilia; with one or two capitate sub-basal setae. Pelta triangular, reticulate, with paired campaniform sensilla; tergites II–VII with two pairs of sigmoid wing-retaining setae; tergite IX setae S1 and S2 shorter than tube, bluntly pointed to weakly capitate, S3 acute; anal setae long.

Male similar to female; sternite VIII without pore plate.


Adult body size varies considerably, both within and between sexes. Large males have much larger fore legs than small males.
