Apenesia eura Alencar & Azevedo , sp. nov.

( Figs 3E , 6C , 8D , 11C , 13M , 19 A–C)

Description. Holotype. Male. Length 3.7 mm. LFW 3.5 mm.

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

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 small, triangle with distal edges.

Mesosoma. Dorsal pronotal area long. Notaulus present, complete, parallel. Parapsidal signum well delimited. Mesoscutellum as long as wide, posterior margin convex; mesoscutum-mesoscutellar sulcus weakly arched, without fovea on side edge, narrow, deep. Axilla subtrapezoidal, deep, large. Metanotal trough foveolate, metanotal fovea oval; median region narrow, large, with posterior margin straight. Metapectal-propodeal complex short, posterior margin almost straight; metapostnotal median carina absent, metapostnotum rugulose, and weakly coriaceous. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectalpropodeal carina present; 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 straight. Basivolsella apical inner margin smooth. Basiparamere with apical dorsal projection small, apex convex. Cuspis with apical margin with three apical calli, almost equally sized, dorsal end short. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe short; subapical membrane long; aedeagal dorsal cover wide.

Female. Unknown.

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

Distribution. Afrotropical ( Central African Republic).
