Diagnosis

Small; mostly black with yellow markings on mouthparts, base of antenna and tergite 3; hind femur apically pale dotted; head coriaceous with sparse punctures on face; clypeus transverse; inner margins of eyes subparallel; malar line long; antenna short with 23 flagellomeres, penultimate flagellomere distinctly elongate; mesosoma laterally punctate with most of speculum and a dorsal area on pronotum smooth; mesoscutum coriaceous; scutellum coarsely punctate; propodeum rugose punctate; female femoral tooth moderate; ovipositor short, apically slightly sinuous. Male with ocelli strongly enlarged, lateral ocellus touching eye margin; inner margins of eyes moderately diverging ventrally; hind femur stouter, femoral tooth strong and stout; otherwise similar to female.

Differential diagnosis

Small and overall black species with legs lighter, differentiated from all other Afrotropical species by the combination of the coriaceous mesoscutum, the punctate scutellum, the short ovipositor and the antenna with few flagellomeres.

HEAD. Face coriaceous with sparse and shallow punctures; inner eye margins subparallel; clypeus transverse, sparsely punctate, convex in profile view; malar line long; frons, vertex and temple coriaceous; ocellar triangle moderate, equilateral; occipital carina joining ventrally hypostomal carina

above mandible base; antenna short, thin and slender with 23 flagellomeres, first flagellomere distinctly longer than second, penultimate flagellomere elongate.

MESOSOMA. Elongate; pronotum moderately punctate with some ventral crenulations and a smoother postero-dorsal area; mesopleuron and metapleuron densely and deeply punctate, with a large oblique rugulose furrow below speculum, speculum mostly smooth; mesoscutum coriaceous, sculpture apically confluent into transverse rugosities; notaulus moderate; scutellum coarsely punctate; propodeum rugose punctate, area superomedia elongate and hardly delimited laterally beyond anterior transverse carina. Legs. Femoral tooth stout and short.

METASOMA. Tergite 2, apical half of tergite 1 and base of tergite 3 longitudinally aciculate; thyridium subelliptic, its main axis longitudinal; ovipositor short, apically slightly sinuous.
