Hind femora beneath with 1–4 inter spines and without outer spines; hind tibiae above with 55–58 outer and inter spines respectively, arrange in groups, inner subapical spur of hind tibiae slightly longer than hind metatarsus. Hind metatarsus keeled beneath and with an apical spine above ( Fig. 13 View FIGURES 13 – 17 ). Male paraproct distinctly longer than epiproct ( Fig. 14 View FIGURES 13 – 17 ). Dorsolateral lobes of male genitalia sclerotized and elongate ( Figs. 15 View FIGURES 13 – 17 ). Epiphallus of male genitalia strap-shaped ( Fig. 16 View FIGURES 13 – 17 ).
