( Figs 3C , 6A , 8B , 18 D–F)

Description. Holotype. Male. Length 4 mm. LFW 3.2 mm.

Colors. Body dark castaneous; antenna gradually darker distally; metasoma castaneous; mandible and legs yellowish; wings amber, veins dark castaneous.

Head. Head as long as wide, trapezoidal. Frons coriaceous, densely puncticulate; frontal line absent. Vertex straight. Clypeus broad with median lobe subtrapezoidal, median tooth small, apical margin smooth, median carina short in profile. Mandible with three apical teeth, teeth with different size, upper tooth mesad, two upper teeth equally sized. Eye strongly bulging. Ocelli large, triangle with proximal edges.

Mesosoma. Dorsal pronotal area short. Notaulus present, complete, weakly converging posterad. Parapsidal signum well delimited. Mesoscutellum as long as wide, posterior margin convex; mesoscutum-mesoscutellar sulcus strongly arched, with fovea on side edge, wide, deep. Axilla subtrapezoidal, deep, large. Metanotal trough foveolate, metanotal fovea drop-shaped; median region wide, large, with posterior margin straight. Metapectalpropodeal complex short, posterior margin convex; metapostnotal median carina absent, metapostnotum rugulose, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina present; lateral surface of propodeum imbricate, inferior region foveolate. Propodeal declivity foveolate.

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

Female. Unknown.

Material examined. Holotype ♂, CENTRAL AFRICAN REPUBLIC, Prefecture Sangha-Mbaéré, Parc Na- tional de Dzanga-Ndoki, 38.6km 173°S Lidjombo , 2°21.60’N, 16°03.20’E, 26–27.v.2001, Malaise trap, Lowland rainforest, 350m , CAR 01-M231, S. van Noort ( ISAM) . Paratypes: 2 ♂, same data as holotype ( ISAM) .

Comments. This species is promptly recognized by having the head wider than long; the mandible with three very small teeth; the notaulus complete; the mesoscutum-mesoscutellar suture strongly arched, deep and wide; the hypopygeal posterior margin concave and the genitalia with the apical dorsal projection of the basiparamere very large.

Distribution. Afrotropical ( Central African Republic).
