Diagnostic description.— Body small, slender, with wings in both sexes extending beyond apices of hind femora by about half of their length ( Fig. 31 A). Fastigium of vertex short, rounded apically, without ventral keel, as long as eye diameter ( Figs. 31 B-C). Prosternum unarmed. Male stridulatory file nearly straight, 0.87 mm long, 96 μm wide, with 242 closely spaced and relatively very wide teeth ( Fig. 50 D); mirror of stridulatory apparatus approximately rectangular; secondary veinlet next to AA 1 present, parallel; stridulatory area of left wing devoid of secondary venation. Tenth tergite in both sexes with shallow, widely triangular incision; male cercus conical, with small, thick basal spine, and large, heavily sclerotized protuberance midlength, above spine ( Fig. 31 D); female cercus simple, elongately conical, somewhat curved. Male titillators flattened, with apices rounded and each armed with simple, small spine ( Fig. 31 E). Male subgenital plate with shallow, rounded emargination on its hind margin, and no traces of styli; female subgenital plate approximately trapezoidal in shape. Ovipositor short, sickle-shaped, about as long as half of hind femur (ratio ovipositor/ hind femur 0.44-0.55) ( Fig. 31 A). Coloration .— General coloration light green; clypeus and mandibles green; pronotum in both sexes with two thin, yellow stripes on dorsal edges of pronotum; posterior edge of metazona in male sometimes with two small, brown, rectangular markings.
