Description. Holotype. Male. Length 4.2 mm. LFW 2.6 mm.
Colors. Head and mesosoma dark castaneous; antenna, clypeus and metasoma castaneous; legs castaneous and yellowish; wings hyaline, veins 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 crenulate, median carina short in profile. Mandible with five apical teeth, teeth with different size, upper tooth mesad, three upper teeth equally sized. Eye weakly bulging. Ocelli large, triangle with distal 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; mesoscutum-mesoscutellar sulcus weakly arched, narrow, shallow, without fovea on side edge. Axilla subtrapezoidal, deep, large. Metanotal trough mostly imbricate, with few foveae, metanotal fovea drop-shaped; median region wide, narrow, with posterior margin straight. Metapectal-propodeal complex long, posterior margin convex; metapostnotal median carina present, metapostnotum rugulose. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum weakly coriaceous, inferior region coriaceous. Propodeal declivity coriaceous-foveolate.
Metasoma. Petiole short. Hypopygium with plate short, posterior margin almost straight, flap absent. Genitalia: paramere slightly sinuous. Basivolsella apical inner margin projected mesad, large, and acute. Basiparamere with apical dorsal projection large, apex convex. Cuspis with apical margin with two apical calli, almost equally sized, dorsal end short. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe long; subapical membrane short; aedeagal dorsal cover wide.
Female. Unknown.

Comments. This species is unique in having the head slightly wider than long with the vertex convex; the mandible with five teeth, the three upper teeth very small; the pronotum very short; the notaulus complete; the metapostnotum v-shaped and rugulose; the genitalia with the basivolsella apical inner margin projected mesad, forming a deep concavity on the base of the digitus. This projection can be less prominent in some specimens.
Distribution. Oriental ( Malaysia, Indonesia).
