Description.

FEMALE (2 specimens). B 5.8-6.1; A 3. 6-3.7; F 3.7-3.9 (Holotype B 5.8; A 3.6; F 3.7).

Color. Head black with eye margin (except on temple) yellow, clypeus, mandible and palpi reddish, and flagellum tri–colored: basal half dark brown, apical half testaceous, flagellomeres 9-12 white; mesosoma reddish with a yellow longitudinal stripe on lateral part of pronotum, and black parts: remaining of pronotum, subtegular ridge and axillar furrows around scutellum and post–scutellum; wings hyaline, venation light brown; legs reddish with hind tibia and hind coxa largely infuscate; metasoma reddish with tergites 6-7 and extreme base of tergite 1 blackish.

Head. Shining; face transverse, densely punctate, medially protruding into a blunt square tubercle connected to antennal socket by a short transverse carina; clypeus lenticular, transverse, sparsely punctate; malar line moderately long, subocular sulcus present as a granulate groove; mandibles sparsely punctate, moderately long, regularly narrowed toward apex; frons, vertex and temple finely and sparsely punctate; ocellar triangle wider than high; antenna stout with 28-29 flagellomeres.

Mesosoma. Entirely shining; pronotum longitudinally strigose but upper third moderately punctate; mesopleuron densely punctate but posterior margin costulate, speculum smooth, sternaulus deep at anterior third; epicnemial carina ventrally moderate; postpectal carina ventrally absent; metapleuron transversely strigose–punctate, dorsally smooth; mesonotum finely and moderately punctate, notaulus hardly visible near base; scutellum flat, not carinate; propodeum punctate–rugose but area petiolaris transversally striate, carination complete and strong except costula partly obsolete, area superomediaelongate, pentagonal. Wings. Hind wing with distal abscissa of Cu1 fully pigmented, connected to 1/Cu& cu–a, cu–a nearly 3 × shorter than 1/Cu. Legs. Stout and densely punctate; hind femur and hind tibia somewhat swollen.

Metasoma. Shining; metasomal tergites 1-3 densely and shallowly punctate, following tergites alutaceous; ovipositor straight and moderately long.

MALE. Unknown.

Etymology.

Named in honour of the Table Mountain National Park, to which the type locality belongs. In 1503, a Portuguese explorer, Antonio de Saldanha, climbed and named the mountain Taboa do Cabo (= Table of the Cape). Subsequently the mountain became known as Tafelberg (= Table Mountain) to the first European Dutch settlers of the Cape who arrived in 1652.

Distribution.

South Africa (Western Cape).
