Head without distinct elevation between eye and posterior ocellus, reticulate except lower face finely striated, striation not reaching toruli ( Figs 39, 40 View FIGURES 37–42 ). Clypeal margin very shallowly emarginate ( Fig. 39 View FIGURES 37–42 ). Eye ovate, anterior and posterior margins not sinuous ( Fig. 37 View FIGURES 37–42 ). Gena with a very weak lamina near mouth corner. Scrobes very shallow, barely visible in dorsal view of the head ( Fig. 40 View FIGURES 37–42 ). Toruli with lower margins about level with lower margins of eyes ( Fig. 39 View FIGURES 37–42 ). Antenna ( Fig. 41 View FIGURES 37–42 ) with scape reaching median ocellus ( Fig. 39 View FIGURES 37–42 ); both anelli transverse, the second slightly longer than the first; funicular segments longer than wide except fu6, which is slightly transverse, and appears as part of the clava; clava ventrally abruptly narrowing before spicula, sutures hardly visible, oblique; micropilosity area occupying less than 1/3 length of claval body. Relative measurements—head length: 18, width: 33, height: 28; POL: 10; OOL: 4.5; eye height: 16, length: 12.5; IOD: 20.5; eye length dorsally: 12.5; temple length dorsally: 2.5; malar space: 10.5; mouth width: 16; distance between clypeal margin and toruli: 10.5; scape length: 17; pedicel length: 4.5, width: 2.5; pedicel plus flagellum: 36; fu1 length: 3.5, width: 2; fu6 length: 3.5, width: 4; clava length: 9, width: 4.5.

Mesosoma dorsally coarsely reticulate ( Fig. 38 View FIGURES 37–42 ). Notauli almost reaching middle of mesoscutum ( Fig. 38 View FIGURES 37–42 ). Scutellum moderately convex ( Fig. 37 View FIGURES 37–42 ), frenal line absent, but frenal area with finer reticulation than rest of scutellum. Upper mesepimeron smooth. Metapleuron and dorsellum uniformly reticulate. Propodeum inclined ( Fig. 37 View FIGURES 37–42 ), uniformly reticulate except two small depressions near its anterior margin submedially; spiracles oval, spiracular sulci absent (cf. Fig. 11 View FIGURES 7–12 ). Fore wing (cf. Fig. 42 View FIGURES 37–42 ) with basal cell and basal fold glabrous; costal cell with several rows of setae on ventral surface; speculum large, extending to stigmal vein; wing pilosity including marginal fringe short; stigma hardly capitate. Relative measurements—mesosomal length: 36, width: 25, height: 25; mesoscutum length: 14; scutellum length: 14, width: 15; propodeum length: 7; fore wing length: 75, width: 30; M: 15; S: 6.5; P: 11.

Metasoma ovate-acuminate, about as long as head plus mesosoma ( Fig. 37 View FIGURES 37–42 ), dorsally mostly reticulate-imbricate (alveolae wider than long) except for gt1 which is mainly smooth (cf. Fig. 19 View FIGURES 19–22 ). Posterior margin of gt1 sinuous, not incised (cf. Fig. 19 View FIGURES 19–22 ). Ovipositor sheaths short, hardly visible in dorsal view ( Fig. 38 View FIGURES 37–42 ). Relative measurements—metasomal length: 53, width: 24; gt1 length: 9; gt7 length: 3, width: 7.

MALE. Unknown.

Variation. FEMALES. Body length: 1.75–2.30 mm. Metasoma yellow to brown; colour of last metasomal tergite always in contrast with rest of tergites, brown to black, in the latter case with conspicuous metallic reflections. Antenna with fu6 quadrate to slightly transverse. Marginal vein about 2.0–2.3× as long as stigmal vein. Metasoma length about 2.0–2.2× width.

Comments. The new species superficially resembles N. awi , N. gracilis and N. incombo in the usually yellow metasoma. Norbanus breviclava can be separated from all these species mainly by the shape of antenna, with fu6 and clava short. In addition, from N. awi it can be separated by the shorter scape, less extended clypeal striation, and longer POL. From N. gracilis it differs mainly in the position of toruli and shape of eyes, while from N. incombo in the shape of gt1, which has the posterior margin sinuous, but not incised.

Etymology. The name refers to the short clava.

Distribution. Namibia, South Africa, Zimbabwe (Map 3).
