Description. Holotype. Male. Length 3.4 mm. LFW 2.6 mm.

Colors. Body dark castaneous; antenna, clypeus and mandible castaneous; legs castaneous and yellowish; wings hyaline, veins castaneous.

Head. Head as long as wide, quadrate. Frons coriaceous, densely puncticulate; frontal line absent. Vertex slightly convex. Clypeus broad with median lobe subtrapezoidal, median tooth present, and large, apical margin smooth, median carina high in profile. Mandible with three apical teeth, teeth with different size, upper tooth mesad, two upper teeth equally sized. Eye weakly bulging. Ocelli small, triangle with distal edges.

Mesosoma. Dorsal pronotal area long. Notaulus present, incomplete posteriorly, weakly converging posterad. Parapsidal signum weakly impressed. Mesoscutellum longer than large, posterior margin convex; mesoscutummesoscutellar sulcus weakly arched, with fovea on side edge, narrow, shallow. Axilla subtrapezoidal, deep, large. Metanotal trough mostly imbricate, with few foveae, metanotal fovea triangular; median region wide, large, with posterior margin straight. Metapectal-propodeal complex short, posterior margin almost straight; metapostnotal median carina present, metapostnotum irregularly foveolate, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus weakly puncticulate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum imbricate, inferior region imbricate. Propodeal declivity polished-puncticulate.

Metasoma. Petiole short. Hypopygium with plate very short, posterior margin strongly concave, flap present. Genitalia: paramere slightly sinuous. Basivolsella apical inner margin smooth. Basiparamere with apical dorsal projection small, apex convex. Cuspis with apical margin serrate, dorsal end long. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe short; subapical membrane long; aedeagal dorsal cover narrow.

Female. Unknown.

Comments. This species is promptly recognized by having the head square; the ocelli small; the clypeus with the median tooth large; the pronotum long; the notaulus incomplete posteriorly; the mesoscutum-mesoscutellar suture weakly arched and narrow; the metapectal-propodeal complex short with the posterior margin almost straight; the metapostnotum irregularly foveolate anteriorly; the hypopygium plate short, with a flap and the posterior margin concave.

Distribution. Afrotropical ( Central African Republic).
