Middle femora unarmed on ventral surface and with one movable spine on the internal and external genicular lobes respectively ventral side of middle tibiae with two internal and two external spines, apex with one pair of dorsal spines and one pair of ventral spines, one spinule between two ventral end spines. Hind femora ventrally with 6–7 inner spines; tibiae with 31–35 internal spinules and 33–35 external spinules on dorsal surface, subapex with one pair of dorsal spines, apex with one pair of dorsal spines and two pairs of ventral spines; hind metatarsus dorsally with two spinules ( Fig. 3G–H ). Apex of paraproct blunt. Process of male 7th abdominal tergite rather short, the middle of posteromedian process slightly curved downward and narrowed into a trapezoid ( Fig. 3C, E–F ).
