Vestria

Fastigium of vertex about as long as eye diameter, approximately triangular when seen from above, with small tubercles at base dorsally; gap between fastigia of vertex and frons shallow. Eyes small relative to head size but strongly protruding. Tegumen of head smooth, with weak traces of genal carinae. Dorsal surface of pronotum smooth, shiny, cut by three transverse sulci; anterior dorsal margin straight, posterior one weakly convex. Thoracic auditory spiracle large, elliptical, completely hidden under lateral lobe of pronotum. Tegmina translucent. Fore coxa with an elongate, forward projecting spine dorsally; tympanum on fore tibia bilaterally closed, tympanal slits facing forward; middle tibia unarmed dorsally, ventrally armed on both margins; hind tibia armed on all four dorsal and ventral margins; apex of hind tibia with two pairs of ventral and one pair of dorsal movable spurs. Dorsal surface of abdominal terga smooth, unmodified. Ovipositor slender, upcurved, about as long as hind femur (ratio 0.98–1.09), nearly straight; both dorsal and ventral margins smooth, parallel, narrowing towards apex. General coloration pale green, with pronotum and dorsum of head brown to dark olive green, legs yellowish brown; dorsal part of pronotum with two prominent white spots in metazona; abdomen green dorsally, yellow on sides, with black spot at margin of each tergite; facial markings striking: frontal part of fastigium of vertex, scapi, and most of upper portion of frons white, lower portion of face dark green, clypeus, labrum and mandibles yellow; sometimes mid and hind femora with elongate black spots on inner surfaces; ovipositor yellowish-brown, with lower edge of upper valvula dark brown to black. Pronotum length: male 5.5–6.4 mm, female 6.3–6.8 mm; hind femur length: male 11.8–13.1 mm, female 14–14.5 mm.
