Diagnosis (range of variation from Rousse et al. 2013 ) Small; head transverse, pale yellow with frons, vertex, occiput and sometimes face orange, mesosoma pale yellow with large testaceous to black markings, notaulus and scutellum strongly lighter than remainder of mesonotum; metasoma orange with tergites 1–3 and a variable part of following dark brown to black; face densely and shallowly punctate; inner margins of eyes slightly converging ventrally; clypeus narrow and long, unusually convex, coriaceous; malar line short; antenna with 29–32 flagellomeres; upper head coriaceous; mesosoma moderately elongate, moderately to densely punctate, but upper pronotum and ventral half of speculum smoother; area superomedia with lateral margin sometimes evanescent beyond anterior transverse carina; female femoral tooth small, sometimes reduced to a small point but always distinct; ovipositor moderately short, apically straight. B 6.0–6.7; A 2.8–3.5; F 3.1–3.5; CT 1.5; ML 0.4; POL 1.0; OOL 1.1; Fl n-1 1.3 ; ASM 1.9; OT 1.3; FFT 1. Male with ocelli, hind femur and femoral tooth enlarged. POL 0.7; OOL 0.3. Differential diagnosis Small and mostly yellowish species with large black dorsal markings; differentiated from all other Afrotropical species by the combination of the straight ovipositor tip, the narrow clypeus and the converging inner margins of eyes.
