Etymology. This species is named after Jean Risbec for his contribution to the Afrotropical Chalcidoidea .

Diagnosis. In female all funiculars longer than broad, fu1 as long as pedicel ( Fig. 97E View FIGURE 97 ). Mesoscutum smooth anteriorly ( Fig. 99A View FIGURE 99 ). Basal carina of propodeum inverted V-shaped ( Fig. 98B View FIGURE 98 ). Fore wing round apically, with a large dark brown spot below mv, slightly extending into posterior half of wing, reaching base of mv, costal cell dorsally with a row of setae ( Fig. 98E View FIGURE 98 ). Petiole longer than broad, as long as hind coxa, Gt4 much as long as Gt3 ( Fig. 98C View FIGURE 98 ).

In male, body entirely yellowish ( Fig. 99A View FIGURE 99 ). Funiculars much longer than wide, funicle distinctly longer than head width ( Fig. 99B View FIGURE 99 ). Dark brown spot of fore wing longer than wide, costal cell sparsely setose ( Fig. 99D View FIGURE 99 ).

Description of holotype ♀ ( Figs 97–98 View FIGURE 97 View FIGURE 98 ). Length 2.50 mm. Body generally dark brown ( Fig. 97A View FIGURE 97 ), except scape, pedicel, pronotum anterolaterally, fore and mid tibia ventrally and all tarsomeres yellowish; antennal mostly dark brown; pronotum anterolaterally testaceous; fore wing with a dark brown spot below mv, reaching base of mv, lower margin of mv not obscured by dark brown spot ( Fig. 98E View FIGURE 98 ); gaster uniformly coloured ( Fig. 98C View FIGURE 98 ); body setation whitish, setation of fore wing entirely dark.

Head 1.16× as broad as high [HW 162 & HH 140] ( Fig. 97B View FIGURE 97 ); in dorsal view stout, 1.79× as broad as long [HW 240 & HL 134] ( Fig. 97C View FIGURE 97 ); face mostly coriaceous, vertex coriaceous and sparsely punctulate; malar space 0.63× length of eye, [ms 42 & EH 67]; malar sulcus distinct, straight ( Fig. 97D View FIGURE 97 ); genal margin regularly curved, edged but not carinate; antennal toruli widely separated; interantennal space not raised, not carinate laterally; scrobal depression smooth, reaching the median ocellus, not carinate on margin; POL 3× as long as OOL [POL 57 & OOL 19] ( Fig. 97C View FIGURE 97 ); temple rounded, 0.3× the eye length (in dorsal view) [TL 30 & EL 100]; setation oriented downwards on face, outwards on the punctuate frons.

Antenna. Scape reaching above the lower margin of median ocellus, 5.23× as long as broad [SL 68 & SW 13]; fu1 1.9× as long as broad [fu1L 40 & fu1W 21], not longer than pedicel, not bulging dorsally; funiculars (fu2–fu4) with two rows of mps and 3 whorls of adpressed relatively long setae; fu2–fu5 distinctly longer than broad ( Fig. 97E View FIGURE 97 ).

Mesosoma weakly arched dorsally, 1.8× as long as wide (170:95), with deep sculpture ( Fig. 98A View FIGURE 98 ); pronotum with coarse umbilicate punctures; mesepisternum flattened, without any process or raised sculpture on epicnemium; mesoscutum 0.7× as long as wide (70:95), 0.8× longer than length of pronotal collar (70:85), with dense umbilicate punctures, smooth anteriorly; notauli visible, slightly obliterated by mesoscutum sculpture; prepectus bare, slightly sculptured; mesoscutellum with sparse umbilicate punctures laterally and coriaceous sculpture on mesoscutellar disc; mesepimeron transversally strigose; metepimeron subtriangular and areolate with long white hairs; propodeum ( Fig. 98B View FIGURE 98 ) with shallow median depression, without smooth median band, without any median carina; lateral rows of areolae absent; inverted V-shaped basal carina, lateral branches of propodeal basal carina slightly convex.

Fore wing with long marginal fringe, distal margin round; dark brown spot below mv; basal cell more setose; mv distinctly enlarged, normally broadened, in lower margin straight, longer than pmv; stv not curved; pmv not distinct, not longer than stv; ventral side of costal cell densely setose, dorsally with row of setae; speculum present; parastigmal bristles absent.

Legs. Fore coxa without depression on frontal surface, hind coxa bare basodorsally; fore (30:10) and hind femora (32:10); hind tibia dorsally with more than 10 setae, setae shorter than basal tibial width ( Figs 98E, F View FIGURE 98 ).
