MALE (allotype). Differs from the female holotype mainly as follows. Body length: 2.25 mm. Metasoma brownish except extensively pale yellow dorsally and ventrally in proximal 2/3; extreme base of gt1 brownish ( Fig. 70 View FIGURES 63–70 ); flagellum entirely dark brown, except tip of clava, which is lighter ( Fig. 70 View FIGURES 63–70 ). Toruli much closer to median ocellus than to clypeal margin ( Fig. 70 View FIGURES 63–70 ). Scape exceeding level of vertex by about half scape length; funicular segments widened both proximally and distally, mostly with two whorls of long setae each, and separated from each other by long tubular connections; setae on funicular segments emerging at a slightly acute angle to segment, longer than length of segments ( Fig. 70 View FIGURES 63–70 ); length of pedicel plus flagellum about 1.8× head width; claval segments compact. Fore wing disc pilosity less dense. Metasoma elongate, length about 2.8× width, shorter than head plus mesosoma and narrower than mesosoma ( Fig. 70 View FIGURES 63–70 ).

Variation. FEMALES. Body length: 3.0– 4.5 mm. Fu5 rarely not darker than fu1–4 (one female from South Africa); colour of fu1–4 from light brown to dark brown, but at least ventrally usually slightly lighter than fu5–6 and clava. Fu1 length about 2.3–2.5× width. Marginal vein about 2.3–2.7× as long as stigmal vein. Metasoma length about 1.7–2.1× width.

Comments. This new species is very close to N. brevicephalus from which it differs mainly in the characters given in the diagnosis and key. These two species are also somewhat similar to N. garouae , but they both differ from the latter mainly in the shorter temples and larger speculum. One female from South Africa is excluded from the type series because it lacks both antennae.

Etymology. The name refers to the reduced temples.

Distribution. Benin, Cameroon, D. R. Congo, South Africa (Map 5).

Hosts. Unknown.
