Antennae 8-segmented; sutures complete and distinct between all segments; III–IV with thin, Y-shaped sense cones, the arms unusually thin and curving around the segment, narrow apex on IV shorter, wider, more abruptly constricted than III; outer sense cone on VI extending to midpoint of VIII ( Fig. 3 ). Head wider than long; ocellar hump weakly developed, ocelli visible; major setae rudimentary; eyes not bulged, covering lateral side almost completely; genae much reduced, without protruding transparent fringe ( Fig. 2 ). Pronotum reticulate, raised sculpture on lateral margins; median area with transverse reticulations ( Fig. 2 ). Mesonotum anterior margin shallowly notched, not reaching beyond anterior one third; 2 pairs of small setae, the inner pair anterior to the outer pair ( Fig. 4 ). Metanotal median triangle weakly indicated; polygonally reticulate, extending beyond posterior margin, median setae anterior to campaniform sensilla ( Fig. 4 ). Fore wing base humped, costal setae shorter than fringe; first vein with 7 basal setae, 2 at middle and 2 distally, thin and pointed; second vein with 6 setae, curved except last three; clavus with 4 veinal setae but no discal seta; posteromarginal cilia wavy ( Fig. 6 ). Fore tibia with a spine at apex; hind tibia with a row of 11 conspicuous spines on inner side and two stout ones at apex; hind tarsi with a spine at median on inner side and two short, stout ones at apex. Abdominal tergite I reticulations extending beyond margin; median area of II with weak reticulations, laterally with wart-like tubercles; thick sublateral antecostal line on III–VII, laterally forming a posterior directed notch; VIII with complete posteromarginal comb of minute teeth; IX with campaniform sensilla; X asymmetric, median split complete, terminal setae almost half as long as the segment ( Fig. 5 ). Sternites II–VII with 2 pairs of marginal setae on broad craspedum; antecostal lines on III–VII with median concave invagination. Ovipositor long, well developed, exceeding abdominal apex.
