Mid tarsomeres with many setae, longer on tarsomeres 4 and 5. Hind femur bowed on basal third; a series of fine setae with curled tips on basal fourth. Hind tibia with 1 median anterodorsal seta; without anteroventral and posterodorsal. Mid and hind tarsomeres a little flattened. Arolium and pulvillus not enlarged. Wing. Smoky brown.
