Male

BODY. Medium-sized, elongated, finely and more coarsely punctate.

HEAD. Large, shorter than pronotum; face reclinate in profile view, rugosely punctate; frontal ridge distinct, with lateral margins subparallel and somewhat thickened, percurrent to clypeal margin; lateral facial keels distinct, slightly curved; subocular furrow shallow and distinct; vertex convex; fastigium of vertex broad, not reaching beyond basal antennomere, with anterior margin rounded and obtuse, lateral margins nearly parallel, surface of fastigium somewhat concave and separated from vertex by shallow transverse impression. Antennae filiform, 27-segmented, reaching behind posterior margin of pronotum, with antennomeres elongate. Eyes long oval; interocular distance about twice as broad as basal antennomere; genae rugosely punctate.

THORAX. Pronotum longer than broad, more or less cylindrical with sides almost parallel; anterior margin almost straight, posterior margin triangularly rounded; median keel indistinct; both prozona and metazona punctate, first sulcus present only on disc, second and third both on disc and lateral lobes, second sulcus little before, third sulcus distinctly behind middle of pronotum; prozona 1.6 × as long as metazona, lateral lobe longer than high, central region of lateral lobe rugosely punctate, other parts of lobe coarsely punctate. Prosternal spine conical, nearly straight, with apex obtuse. Mesosternal lobes 1.2 × as broad as long, with interspace narrower than lobe, slightly widened posteriorly; metasternal lobes touching each other in middle.

WINGS. Tegmina and hind wings well developed, almost reaching top of hind femur. Tegmen 5.7 × as long as wide, with apex rounded, anterior margin having small basal dilatation; anal vein reaching apical fourth. Wing elongate and relatively narrow, posterior margin slightly undulated.

LEGS. Fore and mid legs normal. Hind femur relatively thick, 4.3 × as long as maximal width, with short attenuated apical part; upper median keels smooth, terminating into very small tooth; kneelobes with very sharp and distinct spine. Hind tibia straight, dilated apically, margins obtuse, with 10 inner and 9 outer spines, outer apical spine absent; inner spurs somewhat longer than outer ones. Hind tarsus short, not reaching hind tibia midlength, first joint with dilated margins, second joint distinctly shorter than first one, third joint shorter than two others together.

GENITALIA. Supra-anal plate triangular, apex obtuse; disc with median basal sulcus and fine transverse sulcus in middle. Cercus conical, nearly straight, with apex subacute, reaching apex of supra-anal plate. Subgenital plate short, apical margin triangularly rounded.

COLORATION. General coloration of male olivaceous green, ventral surface of body yellowish brown. Antennae with first antennomere green and blackish flagellum. Pronotum dark green with black sulci. Tegmen brown, anal area green. Hind wing pale bluish, apex and part of hind margin infumated. Fore and mid legs dark green. Hind femur yellow with three black bands on outer, upper and inner surfaces; knee reddish brown. Hind tibia red with blackish praegenicular ring; tibial spines red with black apex. Hind tarsus reddish.

Female

According to image of one living female ( Fig. 1D View Fig ), females similar to male. General coloration of females documented only with the photo of one living specimen ( Fig. 1D View Fig ), bright olivaceous green.

Distribution
