( Figs 2EView FIGURE 2, 5HView FIGURE 5, 7EView FIGURE 7, 10EView FIGURE 10, 13EView FIGURE 13, 16View FIGURE 16 D–F)

Description. Holotype. Male. Length 3.7 mm. LFW 2.5 mm.

Colors. Body orange castaneous except antenna, mandible and legs yellowish.

Head. Head as long as wide, trapezoidal. Frons weakly coriaceous, sparsely 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 strongly bulging. Triangle with proximal edges.

Mesosoma. Dorsal pronotal area very short. Notaulus present, complete, weakly converging posterad. Parapsidal signum weakly impressed. Mesoscutellum as long as wide, posterior margin almost straight; mesoscutummesoscutellar sulcus weakly arched, without fovea on side edge, narrow, deep. Axilla subtrapezoidal, deep, large. Metanotal trough imbricate, metanotal fovea oval; median region narrow, large, with posterior margin straight. Metapectal-propodeal complex short, posterior margin convex; metapostnotal median carina absent, metapostnotum strigate anteriorly, coriaceous medially, and weakly coriaceous. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina present; lateral surface of propodeum imbricate, inferior region imbricate. Propodeal declivity imbricate.

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 serrate, dorsal end very short. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe long; subapical membrane absent; aedeagal dorsal cover wide.

Female. Unknown.

Material examined. Holotype ♂, ECUADOR, Pichincha, Tinalandia 16 km s., Santo Domingo , 15-vi-1975, S.+ J. Peck ( PMAE). 

Comments. Apenesia berela  is promptly recognized by having the body reddish-brown since other species are usually dark brown or black. Apenesia berela  and A. amenula  have the aedeagus dorsal lobe long, which is unusual within Apenesia  species. However, despite the body color, A. berela  has the mandible with one tooth; the metapostnotal median carina absent and the hypopygium flap and posterior margin concave, whereas A. amenula  has the mandible with five teeth; the metapostnotal median carina present and the hypopygium without a flap and the posterior margin almost straight.

Distribution. Neotropical ( Ecuador).
