Apenesia girena Alencar & Azevedo , sp. nov.

( Figs 3H , 6F , 8G , 11F , 14A , 201-C)

Description. Holotype. Male. Length 3.9 mm. LFW 3.7 mm.

Colors. Body dark castaneous; clypeus, mandible, antenna and metasoma castaneous; legs castaneous and yellowish; wings light amber, veins castaneous.

Head. Head wider than long, rectangular. Frons coriaceous, densely puncticulate; frontal line sulcate. Vertex slightly convex. Clypeus broad with median lobe subtrapezoidal, median tooth small, apical margin smooth, median carina high in profile. Mandible with one apical tooth. Eye strongly bulging. Ocelli large, triangle with proximal edges.

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

Metasoma. Petiole short. Hypopygium with plate 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 with two apical calli, dorsal larger than other, dorsal end short. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe short; subapical membrane short; aedeagal dorsal cover wide.

Female. Unknown.

Comments. This species is similar to A. gabela by having the head wider than long; the notaulus complete; the mesoscutum-mesoscutellar suture weakly arched, wide and deep; the hypopygium with flap and posterior margin strongly concave and the cuspis with two apical calli almost equally sized. However, A. girena has the frons with a sulcus and the paraspicular sulcus weakly foveolate, whereas A. gabela has the frons without a sulcus and the paraspicular puncticulate-foveolate.

Distribution. Afrotropical ( Uganda).
