Holotype: Female ( MNHN): Madagascar, Diégo Suarez, [no date], J. De Gaulle Collection (1919).

Description

Female: Length of body 20 mm, of fore wing 16 mm, of ovipositor 14 mm.

Antennae with more than 72 (apex broken) flagellomeres. Height of clypeus:intertentorial distance:tentorio-ocular distance51.0:3.1:2.2. Width of face:width of head:height of eye51.2:2.2:1.0. Height of face:width of face51.0:1.9. Face punctate with a smooth area on top of clypeus. Clypeus rugose. Frons not depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.1:1.0:3.5. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.8:1.0.

Mesosoma approximately 1.7 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.4:2.8. Length of veins 2-SR:3-SR:rm51.0:3.2:1.5. Length of veins m-cu:2-M51.0:2.9. Length of veins 1-CU1:2- CU151.0:3.5. Shape of 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:tarsus52.2:2.3:1.0. Fore basitarsus 3.8 times longer than deep. Length of hind femur:tibia:tarsus52.0:2.9:1.0. Hind basitarsus 5.0 times longer than deep.

First metasomal tergite 1.1 times longer than wide; median area weakly raised and smooth. Second tergite 1.9 times wider than long; medial area strigose, with a small smooth antero-medial area, also postero-lateral areas smooth. Third tergite 2.3 times wider than long; with strigated transverse furrow on anterior margin, and a smooth furrow on subposterior margin. Antero-median area weakly strigated, lateral and posterior areas of tergite smooth. Tergite four with weak strigation on antero-median area, otherwise smooth. Tergites five to eight smooth.

Yellow except for the following which are black: antenna, small area around stemmaticum, apex of mandibles and ovipositor sheets. Fore wings darkened with hyaline areas as follows: the base of wings from veins 1-M and cu-a, below pterostigma and around vein r-m. Hind wing postero-apically darkened.

Etymology

Named from black hind tibia and tarsi.
