Afrapia globularis sp. n.

Fig. 1

Etymology: The species name is the Latin adjective for ‘globular’, with reference to the form of each of the head, meso- and metasoma of the holotype.

Description: Ground colour dark (pterostigma and venation slightly less so); legs not distinctly preserved but, by inference, pale. Head rounded, slightly wider than mesonotum, with occipital carina complete or almost so (possibly briefly interrupted above and below). Flagellum at least 15- or 16-segmented, gradually narrowed distad, with segments gradually shortening from almost 3 times as long as wide (first and second) to about 1.5 times so. Pterostigma distinctly shorter than distance between base of RS and 2r–rs; 1RS+M subparallel to 1Cu, starting slightly below midlength of basal vein; cell 3rm subquadrate.Areola small, slightly broader than long. Ovipositor straight, parallelsided from above, sheath about as long as distance from pterostigmal base to apex of cell 3r. Body length as preserved 3.9 mm, forewing length to apex of cell 3r ca. 2.8 mm, ovipositor sheath 1.1 mm. Male unknown.

Holotype: ^BP /2/28003-1 & BP/2/28069-1, almost complete, lacking legs (except indistinct traces), most of hind wings and parts of antennae. BOTSWANA: Orapa ; Upper Cretaceous, Turonian.
