Body and legs yellow, fore femora external margins shaded brown, abdominal segments IX–X brownish yellow but particularly shaded near posterior margins; antennal segment I white, II brown, III pale with extreme apex shaded, IV–V pale with apical quarter light brown, VI–VIII brown; fore wings and all major setae pale. Antennae 7-segmented, I with no dorso-apical setae, III–IV with sensorium simple. Head projecting conically in front of eyes, cheeks almost parallel; compound eyes with 5 pigmented facets; ocellar setae III 1.0–1.5 as long as an ocellus and arising between anterior margins of posterior ocelli; mouthcone large, maxillary palps 2-segmented. Pronotum slightly wider at posterior than anterior; posteroangular inner setal pair shorter than outer pair. Prosternal basantra with no setae; ferna continuous medially; meso and meta furca without spinula. Mesonotal anterior campaniform sensilla present. Metanotum weakly reticulate medially, median setae varying in distance from anterior margin; campaniform sensilla absent. Fore wing slender, first vein with 3 widely spaced setae on distal half; second vein with few widely spaced setae; clavus with 4–5 veinal setae, no discal seta. Tergites with weak transverse sculpture medially; II–VIII with craspedum present, campaniform sensilla near posterior margin; tergite IX median dorsal setae slightly stouter than posterior setae, extending just beyond tergal posterior margin, posterior marginal setal pair I shorter than pair II; X with median split incomplete. Sternite II with 1–3 discal setae, III–VII with 5–9 discal setae; II with 2 pairs of marginal setae, III–VII with 3 pairs, all arising at margin on VII.

Male macroptera. Smaller and paler than female; tergite IX with pair of elongate curved processes; sternites with no pore plates.
