Diagnosis. Male: small size; marks on face well developed; propodeal TRN, OBL and lateral carinae absent, anterior portion of propodeal with longitudinal wrinkles; scape slightly turbinate broadened; apical process of S8 elongate, bilobate, with long hairs.
Description. Male (Holotype). Measurements: BL 3.63mm; WL 2.57mm; HL 1.69mm; HW 1.84mm; CI 1.37; SI 2.0.
Coloration: Black. Marks on face whitish as follows: clypeus except anterior tentorial pit; lateral face marks subtriangular, ending obtusely along margins of eyes slightly below the level of lower margins of antennal sockets; most portion of supraclypeal area. The following yellowish: lateral mark on scape; linear marks on lateral portions of pronotal collar; lateral mark on fore tibia, basal 1/3 of middle tibia, basal 1/3 of hind tibia, most parts of all basitarsi. Underside of flagellum brown; pronotal lobe blackish brown; tegula brown; all mediotarsus and distitarsus light brown; veins and stigma of wings brown.
Structure: Scape slightly turbinate broadened; face slightly shiny with minute to fine punctures; clypeus longitudinally lineolate-reticulate, lower portion slightly convex, with minute close punctures; paraocular area longitudinally lineolate-reticulate with indistinct punctures, upper portion with subcontiguous punctures, gently merging into frons; punctures along eye margins larger and sparser; facial fovea indistinct; gena narrower than eyes in lateral view, moderately shiny with fine and sparse to scattered punctures; pronotal collar sligntly convex at lateral portion, thin in the middle; mesoscutum slightly convex, moderately shiny with minute to fine and close punctures; scutellum weakly convex, moderately shiny with fine and close punctures which are larger and sparser than those on mesoscutum; metanotum slightly shiny; mesopleuron moderately shiny with minute to fine and close to sparse punctures; propodeal TRN, OBL and lateral carinae absent, anterior portion of propodeal with longitudinal wrinkles, punctures on lateral area minute to fine and sparse to scattered; T1 shiny with particularly minute and scattered shallow punctures, T2 and following terga moderately shiny with closer punctures.
Pilosity: Hairs white; hairs on vertex dense and short; hairs on apical margin of clypeus short and very sparse; hairs on inner side of scape longer; hairs on mesoscutum and scutellum extremely short and sparse; hairs on metanotum longer; hairs on mesopleuron much longer and denser; hairs on T1 nearly absent, T2 and the following terga longer and denser.
Terminalia: See Figs. 13–18. Apical lobe of S7 reduced and without hairs. Apical process of S8 elongate, bilobate, with long plumose hairs.
