Legs long and slender; fore femora about 2.5 times as long as the pronotum, beneath unarmed, internal knee lobe without spines, genicular lobe with 1 long movable spur; fore tibia beneath with 2 external and 2 internal spurs, between the paired apical spurs with a short spur. Mid femora with a long movable spur on the genicular lobe; mid tibia beneath with 2 external and 2 internal spurs, between the paired apical spurs with a short spur. Hind femora beneath with 9 inter spines and without outer spines, and with 1 black band on dorsal surface; hind tibia above with 28–30 outer spines and 26–28 inter spines, inner subapical spur of hind tibia almost equal to length of hind metatarsus. Hind metatarsus with 2 dorsal spines. Apical half of paraproct compressed ( Fig. 37 ). Apex of process of male 7th abdominal tergite slightly narrower than basal part ( Figs. 38–39 ). Male genitalia with slightly notched apex of dorso-median lobe ( Fig. 40 ).

Female. Subgenital plate subquadrate, both sides of basal part strongly prominent and apex concave ( Fig. 41 ). Ovipositor longer than the half of hind femora.

Coloration. Body brown with darkish marks. Face with 4 darkish longitudinal bands and 2 dark spots near clypeal suture. Posterior of thorax with 1 dark midline. Legs with darkish stripes.
