Apenesia aniela Alencar & Azevedo , sp. nov.

( Figs 2B , 5E , 7B , 10B , 13B , 15 D–F)

Description. Holotype. Male. Length 4 mm. LFW 3 mm.

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

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 three apical teeth, teeth with similar size, upper tooth mesad. Eye weakly bulging. Ocelli large, triangle with proximal edges.

Mesosoma. Dorsal pronotal area very short. Notaulus present, incomplete posteriorly, parallel. Parapsidal signum weakly impressed. Mesoscutellum longer than wide, posterior margin almost straight; mesoscutum-mesoscutellar sulcus weakly arched, with fovea on side edge, narrow, shallow. Axilla drop-shaped, 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 foveolate, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina present; lateral surface of propodeum imbricate, inferior region strigulate. Propodeal declivity polished-foveolate.

Metasoma. Petiole short. Hypopygium with plate very short, posterior margin concave, flap absent. Genitalia: paramere slightly sinuous. Basivolsella apical inner margin projected mesad, large, and convex. Basiparamere with apical dorsal projection small, apex convex. Cuspis with apical margin with two apical calli, almost equally sized, dorsal end long. Aedeagus with two apical lobes, ventral lobe short; dorsal lobe short; subapical membrane long; aedeagal dorsal cover narrow.

Female. Unknown.

Material examined. Holotype ♂, MALAYSIA, Pasoh Forest Res. Negri S., III.18.80, P. & M. Becker, forest ( AEIC).

Comments. This species is unique in having the head wider than long; the mandible with three teeth; the pro- notum very short; the notaulus incomplete posteriorly; the metapostnotum t-shaped and irregularly foveolate; Hypopygium with plate short with posterior margin concave; genitalia with basivolsella apical inner margin projected mesad and convex. The mesosoma of A. aniela is similar to A. cila because of the mesoscutum has incomplete notaulus. A. aniela and A. cila differ from each other especially by the head trapezoidal and rectangular and the hypopygium posterior margin concave and straight, respectively.

Distribution. Oriental ( Malaysia).
