Description. Holotype. Male. Length 4.5 mm. LFW 3.8 mm.

Colors. Body castaneous; antenna, clypeus, mandible and legs yellowish; wings hyaline, veins 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 present, and large, apical margin smooth, median carina high 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 weakly impressed. 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 drop-shaped; median region narrow, large, with posterior margin straight. Metapectalpropodeal complex short, posterior margin almost straight; metapostnotal median carina absent, metapostnotum strigate anteriorly, coriaceous medially, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus weakly puncticulate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum imbricate, inferior region imbricate. Propodeal declivity polished-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 acute.

Material examined. Holotype ♂, COSTA RICA, Puntarenas, R. F. Golfo Dulce, 24km w. Pietdras Blancas , xii- 1989 – iii-1990, P. Hanson, 200m ( PMAE)  . Paratype: COSTA RICA, 1 ♂, Alajuela, Penas Blancas , 23-v-1987, MT  , E. Cruz, 700m ( PMAE)  .

Comments. Apenesia chandela  is similar to A. bifiela  and A. perlonga  in 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. chandela  has the head rectangular with the vertex slightly convex as A. bifiela  , 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 (present in A. bifiela  , absent in A. chandela  .

Distribution. Neotropical ( Costa Rica).
