Norbanus ingens sp. nov.

( Figs 109–114 )

Diagnosis. FEMALE. Head and mesosoma mainly bright blue ( Figs 109–111 ); metasoma entirely reddish ( Figs 109, 110 ); antenna except proximal end of scape and distal end of clava dark brown ( Figs 111, 112 ); eyes bright red ( Fig. 111 ); hind tibia pale yellow ( Fig. 110 ). Head without distinct elevation between eye and posterior ocellus ( Fig. 111 ). POL about 1.1× as long as OOL. Clypeal margin slightly emarginate ( Fig. 111 ). Eye length fully as long as malar space. Antenna filiform, second anellus transverse, clava not wider than distal funicular segments, spicula short ( Fig. 112 ); scape virtually reaching level of vertex. Scutellum moderately convex, not globose ( Fig. 109 ). Upper mesepimeron smooth ( Fig. 113 ). Propodeum inclined ( Fig. 109 ), its lateral surfaces less coarsely reticulate than metapleuron ( Fig. 113 ); spiracular sulci absent. Fore wing length about 2.7× width; speculum small, not reaching beyond distal end of submarginal vein; disc pilosity dense, area between stigmal vein and postmarginal vein mostly pilose ( Fig. 114 ). Metasoma longer than head plus mesosoma ( Fig. 109 ); sculpture on most gastral tergites reticulate, alveolae mostly isodiametric (cf. Fig. 69 ). Posterior margin of gt1 slightly sinuous ( Fig. 110 ).

Material examined. Holotype ♀ ( RMNH). TOGO: “TOGO, DANALO, 5.VI.1984, mal. 3”, “BE.30264” [pinned].

Description. FEMALE (holotype). Colour. Head and mesosoma mainly bright blue, with some sparse green and violet reflections mostly on lateral surfaces of mesosoma ( Figs 109–111, 113 ). Metasoma entirely reddish, ovipositor sheaths black ( Figs 109, 110 ). Body pilosity short whitish ( Figs 111, 113 ). Eyes bright red, ocelli light brown ( Fig. 111 ). Mandibles reddish-brown, teeth darker ( Fig. 111 ). Antenna ( Fig. 112 ) with scape dark brown, whitish at base; pedicel and flagellum dark brown, distal third of clava yellow. Wings hyaline, tegulae, venation and pilosity light brown ( Fig. 114 ). Legs ( Figs 109, 110 ) with all coxae as mesosoma; trochanters and femora reddish, hind femur slightly darker; tibiae and tarsi pale yellow; last tarsal segment light brown, arolia and claws brown.

Body length. 10.5 mm.

Head without distinct elevation between eye and posterior ocellus ( Fig. 111 ). Lower face finely striated, striation not reaching toruli; gena and area between gena and torulus almost smooth, shiny; areas between scrobes and eyes striate-reticulate ( Fig. 111 ); vertex with faint reticulation. Clypeal margin very shallowly emarginate ( Fig. 111 ). Eye ovate, anterior and posterior margins not sinuous ( Fig. 109 ). Gena with a weak lamina near mouth corner. Scrobes very deep, rugose, conspicuous in both frontal and dorsal view of the head ( Fig. 111 ). Toruli with lower margins slightly above lower margins of eyes ( Fig. 111 ). Antenna ( Fig. 112 ) with scape virtually reaching level of vertex; both anelli transverse, the second conspicuously longer than the first; funicular segments longer than wide; clava gradually narrowing before the short spicula, sutures hardly visible, oblique; micropilosity area occupying about half length of claval body. Relative measurements—head length: 27.5, width: 59, height: 45; POL: 10; OOL: 9; eye height: 26, length: 18; malar space: 18; mouth width: 26; distance between clypeal margin and toruli: 20; scape length: 24.5; IOD: 35; eye length dorsally: 17; temple length dorsally: 8; pedicel length: 5, width: 2.5; pedicel plus flagellum: 65; fu1 length: 13, width: 3; fu6 length: 5.5, width: 3.5; clava length: 10, width: 3.5.

Mesosoma dorsally coarsely reticulate ( Fig. 110 ). Notauli reaching about 2/3 length of mesoscutum ( Fig. 110 ). Scutellum convex ( Fig. 109 ), frenal line absent, but frenal area with finer reticulation than rest of scutellum. Upper mesepimeron mainly smooth ( Fig. 113 ). Metapleuron and dorsellum uniformly reticulate. Propodeum uniformly reticulate except two very small depressions near its anterior margin submedially, spiracles oval; spiracular sulci absent (cf. Fig. 164 ); lateral surface of propodeum less coarsely reticulate than metapleuron ( Fig. 113 ). Fore wing ( Fig. 114 ) with basal cell and basal fold glabrous; costal cell with several rows of setae on ventral surface; speculum small, not reaching beyond distal end of submarginal vein, disc pilosity dense, area between stigmal vein and postmarginal vein mostly pilose; marginal fringe very short; stigma hardly capitate. Relative measurements— mesosomal length: 68, width: 54, height: 52; mesoscutum length: 30; scutellum length: 25, width: 33; propodeum length: 13; fore wing length: 130, width: 48; M: 21; S: 9; P: 18.

Metasoma acuminate, longer than head plus mesosoma ( Figs 109, 110 ), dorsally entirely finely reticulate (alveolae mostly isodiametric) (cf. Fig. 69 ). Posterior margin of gt1 slightly sinuous, not incised ( Fig. 110 ). Ovipositor sheaths short, hardly visible in dorsal view ( Fig. 110 ). Relative measurements—metasomal length: 125, width: 48; gt1 length: 17; gt7 length: 12, width: 14.5.

MALE. Unknown.

Comments. This species most closely resembles N. polaszeki , from which it greatly differs mainly in body colour, but also regarding the sculpture of metapleura, lateral surfaces of propodeum and dorsal surface of metasoma.

Etymology. From the Latin word ingens , meaning huge, great.

Distribution. Togo (Map 7).

Hosts. Unknown.
