Apenesia gabela Alencar & Azevedo , sp. nov.

( Figs 3G , 6E , 8F , 11E , 13O , 19 G–I)

Description. Holotype. Male. Length 5 mm. LFW 4.4 mm.

Colors. Body dark castaneous; clypeus, antenna, metasoma castaneous; mandible yellowish; legs castaneous and yellowish; wings 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 short in profile. Mandible with one apical tooth. 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 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 drop-shaped; median region wide, large, with posterior margin straight. Metapectal-propodeal complex short, posterior margin almost straight; metapostnotal median carina absent, metapostnotum rugulose, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus puncticulate-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 straight. Basivolsella apical inner margin smooth.Apex convex. Cuspis with apical margin with two apical calli, almost equally sized, dorsal end short. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe short; subapical membrane short; aedeagal dorsal cover narrow.

Female. Unknown.

Material examined. Holotype ♂, UGANDA, Kibale National Park, Kanyawara, Makerere University Bio- logical Field Station , 0°33.859’N, 30°21.630’E, 31.vii–3.viii.2005, Malaise trap, primary mid-altitude Rainforest, 1505m, UG05 -M08, S. van Noort ( ISAM) . Paratypes: 1 ♂, same data as holotype ( ISAM); UGANDA, Kibale National Park, Kanyawara, Makerere University Biological Field Station , Malaise trap, primary mid-altitude Rainforest, S. van Noort , 2 ♂, 0°33.859’N, 30°21.630’E, 31.vii–3.viii.2005, 1505m, UG05 -M07; 12 ♂, 0°33.408’N, 30°22.603’E, 30.vii–5.viii.2005, 1587m, UG05 -M10 ( ISAM).

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

Distribution. Afrotropical ( Uganda).
