Description

Female: Length of body 13 mm, of fore wing 11 mm, of ovipositor 12 mm.

Antennae with 99 flagellomeres. Terminal flagellomere 2.5 times longer than wide. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:4.8:4.7. 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. On top of clypeus a smooth triangle-shaped area. Clypeus rugose. Frons depressed and smooth, with a medial longitudinal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.0:2.5.

Length of eye in dorsal view:distance of occiput and posterior margin of eye52.0:1.0.

Mesosoma approximately 1.6 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.3:3.9. Length of veins 2-SR:3-SR:rm51.0:2.0:1.2. Length of veins m-cu:2-M51.0:2.6. Length of veins 1-CU1:2- CU151.0:5.3. 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:basitarsus52.2:2.2:1.0. Fore basitarsus 3.8 times longer than deep. Length of hind femur:tibia:basitarsus52.0:2.8:1.0. Hind basitarsus 4.5 times longer than deep.

First metasomal tergite 1.3 times longer than wide; raised median area smooth with medial longitudinal groove, posterior half finely and densely strigated. Second tergite 1.8 times wider than long; strongly medially raised, and striated to rugose. Antero-medial triangular area raised and also strongly sculptured, anteriorly smooth. Third tergite 2.6 times wider than long; transverse furrows on anterior and subposterior margins strigated, raised medial area finely strigated. Antero-lateral areas smooth. Tergites four and five with anterior and subposterior strigated furrows, raised median areas finely strigated in tergite four and smooth in tergite five. Antero-lateral areas smooth. Tergite six smooth with transverse strigated furrow on anterior margin. Tergites seven and eight smooth.

Black to dark brown except for metasomal tergites two to eight which are red. Head with reddish-brown lines around eyes and spots on dorsal side posterior to toruli. Wings dark brown, with hyaline areas on fore wing below pterostigma and weakly around vein r-m. Apical half of pterostigma darkened.
