( Figs 2F View FIGURE 2 , 5I View FIGURE 5 , 7F View FIGURE 7 , 10F View FIGURE 10 , 13F View FIGURE 13 , 16 View FIGURE 16 G–I)

Description. Holotype. Male. Length 5.9 mm. LFW 4.3 mm.

Colors. Head and body castaneous; metasoma light castaneous; antenna, clypeus, mandible and legs yellowish; wings hyaline, veins castaneous.

Head. Head wider than long, rectangular. Frons 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 short. Notaulus present, complete, strongly converging posterad. Parapsidal signum well delimited. Mesoscutellum as long as wide, posterior margin convex; mesoscutum-mesoscutellar sulcus weakly arched, narrow, shallow, without fovea on side edge. Axilla drop-shaped, 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 present, metapostnotum strigate anteriorly, and imbricate. Metapectal-propodeal complex imbricate; Paraspicular sulcus imbricate; lateral carina of metapectal-propodeal carina absent; 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 projected mesad, small, and acute. Basiparamere with apical dorsal projection large, 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 narrow.

Female. Unknown.

Material examined. Holotype ♂, GUATEMALA: Izabal, Las Escobas , 200 m, [15°41’N], [88°39’W], V-1987, [M.] Sharkey [col.] ( PMAE) GoogleMaps . Paratypes: 1 ♂, same data as holotype ( PMAE) GoogleMaps ; BRAZIL, 1 ♂, Amazonas, 71°38’W, 4°33’S, IX.’80, Alvarenga ( AEIC) GoogleMaps .

Comments. This species is unique in having the dorsal part of the metapectal-propodeal complex entirely imbricate. A. bifiela is similar to A. chandela and A. perlonga by having the head wider than long, rectangular; the mandible with one tooth; the pronotum short; the notaulus complete and convergent posteriorly and the hypopygium with a flap and the posterior margin concave. However, A. bifiela has the head rectangular with the vertex slightly convex as in A. chandela , whereas A. perlonga has the head rectangular with the vertex straight. Apenesia bifiela differs from A. chandela by the presence of a metapostnotal median carina.

Distribution. Neotropical ( Guatemala, Brazil).
