Distinguishing features
Both sexes fully winged. Body brown to dark brown, tarsi and fore tibiae paler; antennal segments III � V and basal half of VI yellow; forewings light brown. Head wider than long; three pairs of ocellar setae present, pair III slightly longer than distance between hind ocelli, arising just anterior to these ocelli. Antennae 8-segmented; segments III � IV with short forked sensorium. Pronotum with transverse lines of sculpture; two pairs of long posteroangular setae; four pairs of posteromarginal setae. Metanotum weakly reticulate, posterior reticles forming distinctive arc at posterior margin; median setae arising at anterior margin; campaniform sensilla absent. Forewing first vein with two to four setae on distal half; second vein with complete row of about 12 setae. Abdominal tergites III � VII with no sculpture medially; tergite VIII with no ctenidia but with several scattered microtrichia anterior to spiracle, posteromarginal comb with short microtrichia laterally but absent medially; tergite X with complete longitudinal split. Sternites without discal setae. Male smaller; sternites III � VII with large oval glandular area occupying half the length of each sternite.
Variation
This common species in weedy yellow Asteraceae flowers is variable in body size and color, but has distinctive sculpture on the metanotum.
