Description. Holotype. Male. Length 4.8 mm. LFW 4.1 mm.

Colors. Body reddish castaneous; metapostnotum-propodeal complex black; antenna, clypeus, mandible and legs castaneous; wings hyaline, veins castaneous.

Head. Head wider than long, trapezoidal. Frons weakly coriaceous, densely puncticulate; frontal line sulcate. Vertex straight. Clypeus broad with median lobe subtrapezoidal, median tooth present, and large, 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 weakly impressed. Mesoscutellum as long as wide, posterior margin convex; mesoscutum-mesoscutellar sulcus weakly arched, without 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 present, metapostnotum irregularly strigate, and polished. Metapectal-propodeal complex imbricate; Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum foveolate and 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 acute. Cuspis with apical margin with two apical calli, ventral larger than other, dorsal end long.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 Apenesia kelsiela by having the head wider than long; the mandible with one tooth; the notaulus complete; the mesoscutum-mesoscutellar suture weakly arched, wide and deep; the hypopygium with flap and posterior margin concave. However, A. juliela has the metapostnotum irregularly strigate and the metapostnotal median carina present, whereas A. kelsiela has the metapostnotum almost all polished, being only strigate anteriorly and the metapostnotal median carina absent.

Distribution. Neotropical ( Costa Rica, Brazil).
