Diagnosis (updated from Rousse et al. 2013)

Small; pale yellow to testaceous orange with very variable dark markings on inter-ocellar area, around scutellum and on metasoma; flagellum dark brown, basally yellow; face shallowly punctate; inner margins of eyes subparallel; clypeus smooth, strongly transverse; malar line moderately long; occipital carina joining hypostomal carina shortly above mandible base; antenna short with 23–27 flagellomeres, penultimate flagellomere subquadrate; mesosoma moderately elongate, laterally densely and shallowly punctate-granulate including most of speculum but pronotum dorsally smooth, mesoscutum coriaceous with some punctures along notaulus, scutellum almost smooth; propodeum with area superomedia often weakly delimited laterally beyond anterior transverse carina; female femoral tooth small, followed by minute denticles; ovipositor long, its apex weakly sinuous. B 4.5–4.9; A 2.3–2.5; F 2.4–2.8; CT 2.2; ML 0.6; POL 1.0; OOL 1.3; Fl n–1 1.1; ASM 1.8; OT 1.8–2.0; FFT 1. Male with inner margins of eyes diverging ventrally, ocelli strongly enlarged, hind femur and femoral tooth stouter, scutellum quite smooth. POL 0.6; OOL 0.3.

Differential diagnosis

Small and mostly yellowish with variable dark dorsal markings; differentiated from all other Afrotropical species by the combination of the short antenna (basally yellow fading to dark brown), the mesoscutum coriaceous with only few punctures along the notaulus, the strongly transverse clypeus and the short female femoral tooth.
