Hind femora beneath with 7–9 inter spines and without outer spines; hind tibiae above with 65–75 outer spines and 66–74 inter spines, arrange in groups, inner subapical spur of hind tibiae almost equal the length of hind metatarsus. Hind metatarsus with bristles beneath and an apical spine above. Epiproct prolong backwards and with a hollow in the middle part from above, apex with a distinct incision (Fig. 6).
