Apenesia goela Alencar & Azevedo , sp. nov.

( Figs 4A , 6G , 8H , 11G , 14B , 20 D–F)

Description. Holotype. Male. Length 4.9 mm. LFW 4.3 mm.

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

Head. Head wider than long, rectangular. Frons coriaceous, densely puncticulate; frontal line absent. Vertex straight. Clypeus broad with median lobe subtrapezoidal, median tooth present, and large, apical margin crenulate, median carina high in profile. Mandible with three apical teeth, teeth with different size, upper tooth mesad, uppermost much smaller than others. Eye weakly bulging. Ocelli large, triangle with distal edges.

Mesosoma. Dorsal pronotal area short. Notaulus present, incomplete posteriorly, weakly converging posterad. Parapsidal signum weakly impressed. Mesoscutellum longer than large, posterior margin almost straight; mesoscutum-mesoscutellar sulcus weakly arched, without fovea on side edge, narrow, deep. Axilla subtrapezoidal, deep, large. Metanotal trough mostly imbricate, with few foveae, metanotal fovea triangular; median region wide, large, with posterior margin convex. Metapectal-propodeal complex short, posterior margin almost straight; metapostnotal median carina absent, metapostnotum row of anterior foveae, and polished. Metapectal-propodeal complex weakly imbricate; Paraspicular sulcus weakly puncticulate; lateral carina of metapectal-propodeal carina present; lateral surface of propodeum imbricate, inferior region foveolate. Propodeal declivity polished-puncticulate.

Metasoma. Petiole long. Hypopygium with plate very short, posterior margin concave, flap absent. Genitalia: paramere slightly sinuous. Basivolsella apical inner margin projected mesad, small, and acute. Basiparamere with apical dorsal projection large, apex convex. Cuspis with apical margin with one callus, dorsal end long. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe short; subapical membrane absent; aedeagal dorsal cover narrow.

Female. Unknown.

Material examined. Holotype ♂, UGANDA, Kibale National Park, Kanyawara, Makerere University Biologi- cal Field Station , 0°33.859’N, 30°21.630’E, 5–12.viii.2005, Malaise trap, primary mid-altitude Rainforest, 1505m, UG05 -M17, S. van Noort ( ISAM).

Comments. This species is similar to A. singularis by having the pronotum short, the metapostnotum mostly polished with a row of foveae anteriorly. However, A. singularis has the mandible with four teeth; the notaulus complete; the mesoscutum-mesoscutellar suture straight and shallow; the hypopygium plate long and the cuspis with three apical calli, whereas A. goela has the mandible with three teeth; the notaulus incomplete posteriorly; the mesoscutum-mesoscutellar suture weakly arched and deep; the hypopygium plate short and the cuspis with one apical callus.

Distribution. Afrotropical ( Uganda).
