Holotype: Female ( BMNH): Saudi Arabia, Taif, 17.6.1934, J.B. Philby.

Description

Female: Length of body 14 mm, of fore wing 14 mm, of ovipositor 15 mm.

Antennae with 88 flagellomeres, but apex of antennae broken. Height of clypeus:intertentorial distance:tentorio-ocular distance51.0:3.6:3.5. Width of face:width of head:height of eye51.3:2.2:1.0. Height of face:width of face51.0:1.8. Sculpture on face punctate with punctulation. Clypeus rugose. Frons depressed and smooth, with a medial longitudinal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.1:1.0:3.0.

Length of eye in dorsal view:distance of occiput and posterior margin of eye51.2:1.0.

Mesosoma approximately 1.7 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.6:4.7. Length of veins 2-SR:3-SR:rm51.0:1.9:1.0. Length of veins m-cu:2-M51.0:2.6. Length of veins 1-CU1:2- CU151.0:6.8. Vein 1-SR+M curved slightly towards posterior margin close to vein 1-M, otherwise straight. Swelling in vein 3-CU1 1.5 times thicker than the other part of the vein.

Legs: length of fore femur:tibia:basitarsus52.3:2.8:1.0. Fore basitarsus 4.8 times longer than deep. Length of hind femur:tibia:basitarsus51.8:2.6:1.0. Hind basitarsus 5.6 times longer than deep.

First metasomal tergite 1.7 times longer than wide; raised median area smooth with medial longitudinal groove, posterior margin strigated. Second tergite 1.5 times wider than long; medially strigated. Antero-medial triangular area raised and rugose, anteriorly smooth. Third tergite 2.0 times wider than long; transverse furrows on anterior and subposterior margins strigated, raised medial area strigated. Antero-lateral areas smooth. Tergites four and five with anterior and subposterior strigated furrows, raised median area strigose in tergite four and smooth in five. Antero-lateral areas smooth. Tergites six to eight smooth.

Orange-yellow except for the following which are black: area around stemmaticum, antennae, apex of mandibles and ovipositor sheets. Wings darkened with hyaline areas in fore wing below pterostigma and in hind wing on the base of the marginal cell. Apical third of the pterostigma darkened.
