Description

Female: Length of body 17 mm, of fore wing 16 mm, of ovipositor 12 mm.

Antennae with 106 flagellomeres, terminal flagellomere 2.0 times longer than wide. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.7:3.0. Width of face:width of head:height of eye51.0:2.0:1.0. Height of face:width of face51.0:1.7. Sculpture on face fairly smooth, scarce punctuation with hairs. Smooth oval area on top of clypeus. Clypeus pustulate. Frons depressed, punctulated, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.3:3.4. Length of eye in dorsal view:distance of occiput and posterior margin of eye53.2:1.0.

Mesosoma approximately 1.4 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:3.2:3.7. Length of veins 2-SR:3-SR:rm51.0:2.7:1.4. Length of veins m-cu:2-M51.0:2.8. Length of veins 1-CU1:2- CU151.0:6.7. Shape of vein 1-SR+M straight, but angled close to vein 1-M. Swelling in vein 3-CU1 2.0 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.2:2.5:1.0. Fore basitarsus 3.8 times longer than deep. Length of hind femur:tibia:tarsus52.5:2.9:1.0. Hind basitarsus 3.7 times longer than deep.

First metasomal tergite 1.5 times longer than wide; raised median area smooth. Second tergite 1.8 times wider than long; median triangular area distinctive, raised and smooth. Scarce transverse carinae around triangular area. Third tergite 2.2 times wider than long; with weakly strigated transverse furrows on anterior and subposterior margins, raised median and antero-lateral areas smooth. Tergites four and five similar to three, but anterolateral areas more narrow. Tergites six to eight smooth.

Head, antennae, middle tibia and tarsi, hind legs and ovipositor sheets black. Apical third of ovipositor hair yellowish-white. Mesosoma, fore legs, mid femur and anterior third of hind coxa orange-red. Abdomen dark metallic blue. Fore wings dark brown with a metallic blue tinge. Narrow hyaline area below pterostigma which is dark brown. Hind wings evenly dark.
