Re-description.

Medium-sized, predominantly green typical Phaneropterinae with narrow and elongate tegmina surpassed at their apices by the alae. Fastigium verticis smaller than the width of the scapus; triangular and sulcate above, separated from the conical fastigium frontis by a gap. Antennal sockets elevated beside fastigia. Fore coxa with a spine. Fore and mid femora dorsally rounded, ventrally with very tiny spinules. Hind femora slender, slightly thickened in basal part, with few tiny spinules along the ventral length. Fore tibiae very slender, thickened in the area of the tympana and sulcate dorsally; tympana open on inner, conchate on outer side. Hind tibiae triangular or narrow rectangular in diameter, densely packed along each edge with slender spines; dorsally with a pair of tiny spurs on each side, ventrally with one larger spur on each side. Bases of the tegmina differentiated into flaps; on each of these flaps, a similar shaped stridulatory file on the underside is present. No mirror developed on the right tegmen. Rs vein branching off from the radius basally. Male 10th abdominal tergite usually bilobate, either with evenly rounded lobes, lobes reduced to short bulges or strongly elongated. Male cerci simple, expanded at their tips or differentiated in differently-shaped branches. Subgenital plate elongated (but not markedly surpassing abdominal apex) with mostly a pair of short stout to more slender lobes or unlobed with two rounded apices at the posterior margin.

All checked specimens also have an area of dark cells surrounded by the green more elevated veins in the cubital area of the tegmina.
