Brown, grey dusted; femoro-tibial joints yellow; tarsomeres yellow ventrally. Fore tibia with 1 median posterior seta. Mid femur with 2 posterior preapical setae. Mid tibia with 1 median posterior seta; 1 submedian anterodorsal; without anteroventral seta. Hind tibia with 1 median anterodorsal and 1 submedian anteroventral setae; 1 long dorsal in apical fourth; 1 preapical anterodorsal; basal half with a series of setae on anterodorsal and posterodorsal surfaces.
