Propodeum side graphite gray to black, sparse testaceous plumose hairs, rugulose with dense shallow punctation to granulate at dorsal part of propodeum without punctation, punctures separated by 0.1 puncture diameter ( Fig. 1f View FIGURE 1 ). Tegula black to hyaline-testaceous at external edge, sparse punctation, punctures separated by 1–4 puncture diameters, underlying surface slightly coriaceous ( Fig. 1c View FIGURE 1 ). Wings slightly smoked, venation black to dark brown ( Fig. 1a View FIGURE 1 ). Anterior leg graphite gray to black except tarsus orange, testaceous simple hairs. Mid leg graphite gray to black except tarsus and basitarsus orange, testaceous simple hairs. Hind leg black to light orange; coxa and femur graphite gray to black, tibia to tarsus light orange with one black elliptical spot on anterior surface of basitarsus ( Fig. 1g View FIGURE 1 ). Hind leg scopa with testaceous long branched plumose hair ( Fig. 1g View FIGURE 1 ). Pilosity of femur simple and testaceous ( Fig. 1g View FIGURE 1 ).
