Description

Female: Length of body 17 mm, of fore wing 15 mm, of ovipositor 19 mm.

Antennae with 111 flagellomeres, terminal flagellomere 3.0 times longer than wide. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.8:3.2. Width of face:width of head:height of eye51.3:2.3:1.0. Height of face:width of face51.0:2.0. Sculpture on face punctate. Clypeus granulate. Frons depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.3:3.7. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.6:1.0.

Mesosoma approximately 1.5 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:1.9:3.3. Length of veins 2-SR:3-SR:rm51.0:1.6:1.2. Length of veins m-cu:2-M51.0:2.2. Length of veins 1-CU1:2- CU151.0:5.7. 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:tarsus52.1:2.2:1.0. Fore basitarsus 3.0 times longer than deep. Length of hind femur:tibia:tarsus52.0:3.0:1.0. Hind basitarsus 5.5 times longer than deep.

First metasomal tergite 1.4 times longer than wide; raised median area smooth with medial longitudinal depression, posterior margin strigose. Second tergite 1.7 times wider than long; medial area raised and strigose to weakly reticulate. Triangular area anteriorly raised and smooth, posteriorly strigated. Third tergite 2.3 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area strigated, antero-lateral areas smooth. Tergite four similar to three. Tergite five with strigated transverse furrows on anterior and subposterior margins, medial and anterolateral areas smooth. Tergites six to eight smooth.

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