Description

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

Antennae with 104 flagellomeres, terminal flagellomere 2.1 times longer than wide. Apex of antenna flattened. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.6:3.0. Width of face:width of head:height of eye51.2:2.1:1.0. Height of face:width of face51.0:1.9. Sculpture on face pustulate and granulate, on clypeus granulated. Frons slightly depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.4:3.1. Length of eye in dorsal view:distance of occiput and posterior margin of eye52.4:1.0.

Mesosoma approximately 1.8 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.0:3.9. Length of veins 2-SR:3-SR:rm51.0:2.4:1.4. Length of veins m-cu:2-M51.0:2.5. Length of veins 1-CU1:2- CU151.0:6.2. Shape of vein 1-SR+M nearly straight, with a little unevenness. Swelling in vein 3-CU1 2.0 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.1:2.4:1.0. Fore basitarsus 3.8 times longer than deep. Length of hind femur:tibia:tarsus51.9:2.7:1.0. Hind basitarsus 4.3 times longer than deep.

First metasomal tergite 1.7 times longer than wide; raised median area smooth and posterior area strigated. Second tergite 1.7 times wider than long; raised median area 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 longitudinally rugulose to reticulate rugose. Antero-lateral areas raised and smooth. Tergites four and five similar, but raised median areas smooth and antero-lateral areas more narrow. Tergites six and seven smooth.

Orange-brown except for the following which are black: face, frons, vertex, temples, apex of mandibles, antennae and ovipositor sheets. Wings fairly evenly darkened, with a paler area in fore wing below pterostigma. About apical fifth of pterostigma darkened. Hind wing darkened with a paler area on the base of marginal cell.
