 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). Mesoscutum smooth anteriorly (Fig. 99A). Basal carina of propodeum inverted V-shaped (Fig. 98B). 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). Petiole longer than broad, as long as hind coxa, Gt4 much as long as Gt3 (Fig. 98C).   
In male, body entirely yellowish (Fig. 99A). Funiculars much longer than wide, funicle distinctly longer than head width (Fig. 99B). Dark brown spot of fore wing longer than wide, costal cell sparsely setose (Fig. 99D).  
 Description of holotype ♀ (Figs 97–98). Length 2.50 mm. Body generally dark brown (Fig. 97A), 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); gaster uniformly coloured (Fig. 98C); body setation whitish, setation of fore wing entirely dark.   
 Head 1.16× as broad as high [HW 162 & HH 140] (Fig. 97B); in dorsal view stout, 1.79× as broad as long [HW 240 & HL 134] (Fig. 97C); 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); 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); 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).   
 Mesosoma weakly arched dorsally, 1.8× as long as wide (170:95), with deep sculpture (Fig. 98A); 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) 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).   
 Metasoma. Petiole longer than broad dorsally, ventral transverse carina between petiole and St1 absent. Metasoma 1.8× as long as wide (170:95) (Fig. 97C), longer than mesosoma, slightly compressed laterally (Fig. 97D); ventral transverse carina between petiole and St1 absent; petiole in dorsal view longer than wide, as long as or longer than half length of hind coxa; tergites smooth; Gt4 (in lateral view) much as long as Gt3 (at least 1.5× longer), not sinuous posteriorly; Gt5 partly covering Gt6, not sinuous posteriorly; Gt4–Gt5 with few setae dorsally, Gt6 sparsely setose ventrally; ovipositor upturned (Fig. 97C).   
 Male (Fig. 99). Length 2.75–3.00 mm. Exhibiting entirely different colouration, yellowish, with brown band on last four tergites (Fig. 99A); with longer petiole (Fig. 99A); antennal formula 11143; each funicular with 3 rows of mps and several whorls of relatively long and erected setae (Fig. 99B); fore wing entirely setose, without speculum (Fig. 99D).   
 Variation. Length 1.95–3.20 mm. Body brown to yellowish or four distal segments of gaster yellowish brown to yellowish.
