Pyrgocorypha

Fastigium of vertex strongly projecting, triangular when seen from above, two to four times as long as eye diameter, often with apical hook, with distinct gap between fastigium of frons; tegumen of head smooth to moderately granulose, without traces of genal carinae. Eyes small relative to size of head, not particularly protruding. Dorsal surface of pronotum moderately granulose, flat or weakly convex; anterior dorsal margin straight, posterior one straight to weakly convex. Thoracic auditory spiracle large, elliptical, completely hidden under lateral lobe of pronotum. Fore coxa with an elongate, forward projecting spine dorsally. Front tibia unarmed dorsally, both ventral margins with immovable spines as long as 1/4–1/2 diameter of tibia; tympanum on fore tibia bilaterally closed, tympanal slits facing forward, tympanal area weakly swollen, with pair of small pits below tympanal slits. Middle tibia unarmed dorsally, ventrally armed on both margins; hind tibia armed on all four dorsal and ventral margins; apex of tibia with two pairs of ventral and one pair of dorsal movable spurs. Stridulatory area of left wing with dense secondary venation. Posterior margin of male 10th tergite with shallow but distinct emargination. Female 10th tergite with deep furrow along midline and with deep triangular incision apically. Ovipositor weakly curved downwards or distinctly bent upwards at base. Most species have both green and brown color forms, usually with no conspicuous markings; sometimes dorsal surface of pronotum darker than lateral lobes, bordered by light thin stripes; in some species face and ventral part of fastigium of vertex, and sometimes mandibles, have dark markings.
