Hind femora ventrally with 2 inner spines and without outer spines; hind tibiae above with 44–49 outer and inner spines respectively, arrange in groups. Super internal spur of hind tibiae almost at the position of the dorso-apical spine of metatarsus. Hind metatarsus keeled ventrally. Epiphallus of male genitalia with the upper end divided and the lower end notched shallowly ( Figs. 10–12 ).

Female. Subgenital plate with hind margin deeply notched ( Fig. 13 ). Ovipositor shorter than the half of hind femora.
