Holotype: Female ( ZMHB): Goniobracon striolatus Szépligeti 1914 , Sierra leone, [no date], Bingham.

Description

Female: Length of body 20 mm, of fore wing 16 mm, of ovipositor 19 mm.

Antennae with 79 flagellomeres (apex broken). Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:4.4:4.4. Width of face:width of head:height of eye51.3:2.2:1.0. Height of face:width of face51.0:1.9. Sculpture on face pustulate with dense punctulation, on clypeus similar. Frons weakly depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.2:1.0:3.4. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.5:1.0.

Mesosoma approximately 1.7 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.6:4.1. Length of veins 2-SR:3-SR:rm51.0:2.2:1.3. Length of veins m-cu:2-M51.0:2.4. Length of veins 1-CU1:2- CU151.0:4.4. Shape of vein 1-SR+M weakly curved close to vein 1-M, otherwise straight. Swelling in vein 3-CU1 1.3 times thicker than the other part of the vein.

Legs: The type specimen is without forelegs. Length of hind femur:tibia:tarsus52.2:3.1:1.0. Hind basitarsus 4.5 times longer than deep.

First metasomal tergite 1.8 times longer than wide; raised median area smooth, anteriorly depressed and posteriorly strigated. Second tergite 1.8 times wider than long; raised median area strigated, antero-medial triangular area raised and smooth. Third tergite 1.9 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area longitudinally strigose. The centre of tergite raised, lump like. Antero-lateral areas raised and smooth, fairly wide. Tergites four and five similar, but antero-lateral areas more narrow and sculpture on tergite four pustulate to rugulose, tergite five smooth. Tergites six to eight smooth.

Orange-brown except for the following which are black: face, frons, vertex, temples, apex of mandibles, antennae and ovipositor sheets. Narrow orange-brown margins around eyes on dorsal side, and spots posterior to toruli. Wings darkened, with two hyaline areas in fore wing below pterostigma and below vein 1-CU1. Apical third of pterostigma darkened. Hind wing darkened with hyaline area on base of marginal cell.
