Holotype: Male ( MNW): Bathyaulax angolensis Fahringer 1941 . Angola, Luanda, 2.VIII. ’36, Zerny.
Description
Male: Length of body 10 mm, of fore wing 8 mm.
Antennae with 76 flagellomeres, terminal flagellomere pointed, approximately 2.5 times longer than wide. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.3:3.3. Width of face:width of head:height of eye51.2:2.0:1.0. Height of face:width of face51.0:1.8. Sculpture on face fairly strong, pustulate to granulate. Clypeus rugulose. Frons depressed, very sparsely punctulate, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.3:1.0:3.1. Length of eye in dorsal view:distance of occiput and posterior margin of eye52.2:1.0.
Mesosoma approximately 1.9 times longer than maximally deep.
Fore wing: length of veins r:3-SR:SR151.0:2.5:4.3. Length of veins 2-SR:3-SR:rm51.0:2.0:1.1. Length of veins m-cu:2-M51.0:2.8. Length of veins 1-CU1:2- CU151.0:7.8. Vein 1-SR+M weakly convex, curving slightly downwards to both 1-M and 2-SR+M. Vein 3-CU1 only slightly swollen posteriorly, about 1.3 times thicker than the other part of the vein.
Legs: length of fore femur:tibia:basitarsus51.9:2.2:1.0. Fore basitarsus 4.3 times longer than wide. Length of hind femur:tibia:basitarsus52.1:3.0:1.0. Hind basitarsus 5.0 times longer than deep.
First metasomal tergite 1.8 times longer than wide; raised median area with strong medio-longitudal furrow, latero-longitudinally striated. Second tergite 1.6 times wider than long; with raised smooth triangular area on anterior part of tergite. Longitudal strigation posterior from triangular area, not reaching the posterior margin of the tergite. Third tergite 2.0 times wider than long. Transverse furrows on anterior and subposterior margins strigated, transverse area in between smooth, longer medially than laterally. Tergites four and five with strigated transverse furrows on anterior and posterior margins, and smooth lateral areas surrounded by similar furrows. Tergites six to eight smooth.
Orange-brown except for the following which are black: antenna, temples and frons, vertex, face and apex of mandibles. Wings fairly evenly darkened, with a faint hyaline zones in fore wings. Basal two-thirds of pterostigma yellowish white.
