Description

Female: Length of body 20 mm, of fore wing 16 mm, of ovipositor 22 mm.

Antennae broken (only 28 flagellomeres remaining). Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:4.2:3.4. Width of face:width of head:height of eye51.1:2.3:1.0. Height of face:width of face51.0:1.8. Sculpture on face medially pustulate and laterally punctulate. Clypeus granulate. Frons weakly depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.0:2.8. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.5:1.0.

Mesosoma approximately 1.7 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:1.9:3.7. Length of veins 2-SR:3-SR:rm51.0:1.8:1.1. Length of veins m-cu:2-M51.0:2.2. Length of veins 1-CU1:2- CU151.0:4.7. Shape of vein 1-SR+M straight. Swelling in vein 3-CU1 1.6 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.1:2.2:1.0. Fore basitarsus 4.8 times longer than deep. Length of hind femur:tibia:tarsus52.0:2.9:1.0. Hind basitarsus 5.0 times longer than deep.

First metasomal tergite 1.5 times longer than wide; raised median with medial longitudinal groove, posterior margin strigose. Second tergite 1.6 times wider than long; medial area raised and strigose. Antero-medial triangular area raised, anteriorly smooth and posteriorly rugose. Third tergite 2.0 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area medially strigated and sublaterally smooth, antero-lateral areas smooth. Tergites four and five with strigated transverse furrows on anterior and subposterior margins, antero-lateral areas smooth and raised. Tergite four raised median area reticulate to rugose, in tergite five smooth. Tergites six to eight smooth.

Yellow except for the following which are black: antenna, stemmaticum, apex of mandibles and ovipositor sheets. Wings darkened with hyaline areas in fore wing below pterostigma and in hind wing in the base of the marginal cell. Apical quarter of pterostigma darkened.
