Body. Length, male 7.5 mm to tip of the forewing; female 8.0– 8.5 mm to the tip of forewing, 9.0– 9.5 mm to the end of ovipositor. Male vertex subtriangular, acute apically, declined forward anteriorly; ocellus close to corresponding eye. Female vertex broad, subangular, slightly upturned anteriorly; ocellus distant from eye at 1.2 time its length. Measurements of vertex length: interocular width: pronotal length (mm): male 1.2: 1.5: 1.0, female 1.62: 1.62: 1.0. Pronotum slightly wider than head.
