Description

Female: Length of body 16 mm, of fore wing 14 mm, of ovipositor 16 mm.

Antennae with 93 (apex broken) flagellomeres. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.4:3.0. Width of face:width of head:height of eye51.3:2.2:1.0. Height of face:width of face51.0:1.9. Sculpture on face punctate with punctulation. Clypeus rugose. Frons depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.2:1.0:3.4. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.5:1.0.

Mesosoma approximately 1.6 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.1:3.9. Length of veins 2-SR:3-SR:rm51.0:2.1:1.4. Length of veins m-cu:2-M51.0:2.2. Length of veins 1-CU1:2- CU151.0:4.1. Shape of vein 1-SR+M straight but angled close to vein 1-M. Swelling in vein 3-CU1 1.4 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.4:2.8:1.0. Fore basitarsus 4.0 times longer than deep. Length of hind femur:tibia:tarsus52.3:3.3:1.0. Hind basitarsus 4.3 times longer than deep.

First metasomal tergite 1.5 times longer than wide; raised median area smooth with medial longitudinal groove, posterior margin strigose. Second tergite 1.9 times wider than long; medial area raised and strigose. Antero-medial triangular area raised, anteriorly smooth and posteriorly strigated. Third tergite 2.3 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area weakly strigated, anterolateral areas smooth. Tergites four and five with strigated transverse furrows on anterior and subposterior margins, antero-lateral areas smooth. Sculpture on tergite four raised median area weakly rugulose, in tergite five smooth. Tergites six to eight smooth.

Yellow except for the following which are black: antenna, frons and a small area around stemmaticum, apex of mandibles and ovipositor sheets. A dark brown small spot on top of clypeus. Fore wing darkened with a hyaline zone below pterostigma. Hind wing also darkened with a hyaline area in the base of the marginal cell. The apical third of pterostigma darkened.
