Head sculptured with reticles dorsally, posterior fourth with transverse reticles; ocellar setae III situated near the outside of anterior margins of ocellar triangle; 5 pairs of postocular setae arranged close to compound eyes ( Fig. 2 View FIGURES 1–7 ). Antennae 8-segmented, segments III–IV with short forked sense cone; segment III longest and asymmetrical, dorsal side with 8–9 microtrichial rows, ventral with 6–8 rows; segment IV with 6–8 microtrichial rows; segment V as long as or longer than VI, with 6–7 microtrichial rows; segment VI with one long inner sense cone and two short outer sense cones, 4–6 microtrichial rows. ( Fig. 3 View FIGURES 1–7 ).

Pronotum surface with sculptured reticulations and about 30 discal setae, all setae short and flattened, no long setae ( Fig. 2 View FIGURES 1–7 ). Mesonotum with regular reticles, medial and submedial setae short and flattened, situated on posterior part, CPS present anteromedially. Metanotum reticulate, median pair of setae flattened and behind anterior margin, submedian setae near anterior margin, CPS present. Mesosternum and metasternum setae fine ( Fig. 5 View FIGURES 1–7 ). Tarsi 2- segmented. Fore wing vein setae short and flattened, costal vein setae clearly shorter than costal cilia, apex with 1 terminal seta; first vein with 6–7 basal setae and 3 distal setae, second vein with 7 setae scattered ( Fig. 4 View FIGURES 1–7 ).

Abdominal tergite I sculptured with transverse reticles, tergites II–VIII smooth medially, laterally with transverse reticulations. Tergites discal setae S1 and S2 small, setae S1 arising from anterior half, setae S3 on tergites II–IV stout but small on tergites V–VIII, posteroangular setae arising mesad of posterior angle. Tergites I–VII medially with short posteromarginal craspeda. Tergite VIII with complete posteromarginal comb, CPS very close to posterior margin ( Fig. 6 View FIGURES 1–7 ). A patch of microtrichia present on the anterior angle of tergite VII–VIII. Tergite IX MD setae longest; tergite X with median split complete. Pleurites without discal setae. Sternites with weak transverse reticles, no discal setae; sternite VII with 3 pairs of posteromarginal setae in front of posterior margin ( Fig. 7 View FIGURES 1–7 ).
