Description

Female: Length of body 14 mm, of fore wing 12 mm, of ovipositor 13 mm.

Antennae broken. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:4.1:4.0. Width of face:width of head:height of eye51.2:2.1:1.0. Height of face:width of face51.0:1.8. Sculpture on face pustulate with punctulation. Clypeus similar. Frons depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.2:1.0:3.1. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.8:1.0.

Mesosoma approximately 1.7 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.3:3.6. Length of veins 2-SR:3-SR:rm51.0:2.1:1.1. Length of veins m-cu:2-M51.0:2.8. Length of veins 1-CU1:2- CU151.0:5.3. Shape of vein 1-SR+M straight. Swelling in vein 3-CU1 1.3 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.2:2.5:1.0. Fore basitarsus 4.3 times longer than deep. Length of hind femur:tibia:tarsus52.4:3.4:1.0. Hind basitarsus 3.8 times longer than deep.

First metasomal tergite 1.6 times longer than wide; raised median area smooth with a weak medial longitudinal depression, posterior margin strigated. Second tergite 1.8 times wider than long; medial area raised and strigated. Antero-medial triangular area raised and smooth. Third tergite 2.0 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area strigated, antero-lateral areas smooth. Tergites four and five with strigated transverse furrows on anterior and subposterior margins, and medial and antero-lateral areas raised and smooth. Tergites six to eight smooth.

Yellow except for the following which are black: frons and vertex around stemmaticum, apex of mandibles and ovipositor sheets. Antennae brown. Wings darkened with hyaline areas in fore wing below pterostigma and weakly on apical part of basal cell, and in hind wing on the base of the basal cell. Less than fifth on pterostigma apically darkened.
