Legs: fore femur with a posterodorsal row of setae on apical two-thirds becoming shorter basad, a posteroventral row of setae on apical two-thirds becoming shorter basad, and a posterior row of much shorter setae on basal third; fore tibia with an anterodorsal row of short and weak setae, 6 long posteroventral setae on apical half, 1 anterodorsal, 1 dorsal and 1 posteroventral preapical setae, anterior surface with a brush-like ctenidium of golden setulae, and 1 ventral apical seta; fore tarsus with a golden ctenidium and few long setulae on apical half; mid femur with a tubercle at apex of anterodorsal to posterodorsal surfaces bearing about 17–20 short spines, the posterodorsal ones longer, an anterodorsal row of setae on basal half, and 4–5 ventral setae on basal half; mid tibia narrowed at base, with an anterodorsal comb-like ctenidium of short spines on basal fourth and fine setae on apical three-fourths, a posterodorsal row of 4–6 stronger setae on basal two-thirds, 1 strong posterior seta on middle third, 1 anterodorsal and 1 dorsal preapical setae and 2 anteroventral, 1 posteroventral and 2 ventral apical setae; hind femur with an anteroventral row of setae, the 3 apicalmost strongest, an anterodorsal row of setae, a group of posterior setulae at base, and few long posteroventral setulae on apical fourth; hind tibia slightly curved, with 6 short anteroventral setae on apical two-thirds, an anterodorsal row of long and weak setae, a posterodorsal row of weak setae and a long and strong posterodorsal seta on apical third, 3 posteroventral setulae on middle third, 1 dorsal, 1 posterodorsal and no anterodorsal preapical setae, and 1 posteroventral and 1 ventral apical setae; hind tarsus with a golden brush ventrally.
