Apenesia farela Alencar & Azevedo , sp. nov.

( Figs 3F , 6D , 8E , 11D , 13N , 19 D–F)

Description. Holotype. Male. Length 4.5 mm. LFW 4.3 mm.

Colors. Head dark castaneous; antenna gradually darker distally; clypeus and mandible yellowish.

Head. Head wider than long, rectangular. Frons weakly coriaceous, densely puncticulate; frontal line absent. 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 weakly bulging. Ocelli large, triangle with proximal edges.

Mesosoma. Dorsal pronotal area long. Notaulus present, complete, parallel. Parapsidal signum weakly impressed. Mesoscutellum as long as wide, posterior margin almost straight; mesoscutum-mesoscutellar sulcus weakly arched, without 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. Metapectal-propodeal complex short, posterior margin almost straight; metapostnotal median carina absent, metapostnotum irregularly foveolate, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum imbricate, inferior region foveolate. Propodeal declivity 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, ventral 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.

Material examined. Holotype ♂, CENTRAL AFRICAN REPUBLIC, Prefecture Sangha-Mbaéré, Réserve Speciale de Fôret Dense de Dzanga-Sangha , 12.7km 326°NW Bayanga, 3°00.27’N, 16°11.55’E, 11–12.v.2001, Malaise trap, Lowland rainforest, marsh clearing, 420m, CAR01-M90, S. van Noort ( ISAM).

Comments. This species is similar to Apenesia eura by having the pronotum long; the notaulus complete and parallel; the hypopygium with a flap and the posterior margin strongly concave, while A. farela has the mesoscu- tum-mesoscutellar suture wide; the metapostnotum irregularly foveolate anteriorly; the cuspis with two apical calli, ventral one larger than the dorsal with dorsal end short, whereas A. eura has the mesoscutum-mesoscutellar suture narrow; the metapostnotum v-shaped and rugulose; the cuspis with three apical calli, almost equally sized with the dorsal end short.

Distribution. Afrotropical ( Central African Republic).
