(Map. 1, Figs. 6 –7View FIGURE 6View FIGURE 7, 13 View Figure : G–H)

Male. Body small. Fastigium verticis conical, apex obtuse, furrowed in midline. Eyes globular, obviously protruding forwards. Apical segment of maxillary palpi as long as subapical one, apex slightly inflated.

Anterior margin of pronotum straight, metazona slightly raised, posterior margin obtusely rounded; lateral lobe longer than high, humeral sinus absent.

Ventral margins of femora of all legs smooth, without spines. Procoxa with a short spine; protibia with 4 pairs of spines and 1 pair of apical spurs on ventral margin; tibial tympana opened on both sides, oval. Mesotibia with 3 internal spines and 4 external spines on ventral margin, and a pair of ventral apical spurs. Genicular lobes of postfemur with apices obtuse; posttibia with 25–26 dorsal spines on each side, 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Tegmina short, reaching posterior margin of pronotum, visible in lateral view. Hind wings absent.

Posterior margin of tenth abdominal tergite weakly concave. Cerci slightly incurved, interno-dorsal margin of basal area with 1 slightly compressed, comparatively long and triangular process, the apex obtuse; ventral margin of one third basal area with a comparatively short and triangular process, apex obtuse; middle area with 1 spineshaped process on dorsal margin, apex directed interno-dorsad; subapical area slightly expanded, apex subacute. Subgenital plate with base broad, gradually narrowing, basal margin arched excavate, posterior margin concave with a small angular convexity in middle. Subgenital plate with thin and long styli on ventral margin of subapex.

Female. Appearance is similar to male, slightly larger. Cerci conical, apices acute. Ovipositor gently curved upwards, base stout, narrowing, dorsal valvulae slightly longer than ventral ones; dorsal valvulae sharply pointed and ventral valvulae with an indistinct small terminal hook or absent. Subgenital plate with basal half broad, basal margin slightly straight; lateral margins expanded, slightly curved ventrad; apical half narrowing, centre of posterior margin with 1 shallowly concavity.

Coloration. Body brown. Frons, gena and eyes light brown. Internal margin of antennal socket, scape and pedicel black brown. Dorsum of head with 4 brown stripes. Pronotum with a pair of dark brown stripes on lateral margins of disc, between area light brown; lateral lobes light brown. Ventral spines of tibiae, apex of each tibia, whole tarsi and genicular lobes light brown. Male cerci yellowish brown.
