( Figs. 1 –6View FIGURES 1 – 6, 19)

Diagnosis. Male: medium size; marks on face well developed; propodeal TRN, OBL and lateral carinae indistinct, anterior portion of propodeal with transverse wrinkles; scape slightly turbinate broadened. S 8 more or less rhombiform, apical process without hairs, slender and simple.

Description. Male (Holotype). Measurements: BL 6.11mm; WL 4.64mm; HL 1.55mm; HW 1.65mm; CI 1.32; SI 1.67.

Coloration: Black. The following whitish: clypeus except anterior tentorial pit; well developed lateral face marks ending narrowly and rather acutely at eye margins beyond the level of upper margins of antennal sockets; lateral mark on scape; linear band marks on collar of pronotum; apical spots on tubercles (pronotal lobe); lateral mark on fore tibia, basal spot on middle tibia, basal half of hind tibia, all basitarsi; posterior portion of tegula. Underside of flagellum brown; base portion of tegula brown; mediotarsus and distitarsus yellowish brown; veins and stigma brown.

Structure: Scape slightly turbinate broadened; face slightly shiny with fine to moderate punctures; clypeus transverse lineolate-reticulate, with shallow fine close punctures, lower portion slightly convex; paraocular area longitudinally lineolate-reticulate with dense punctures; lower portion of paraocular area punctures become sparse and indistinct; supraclypeal area moderately convex, with fine sparse puntures; frons with close punctures; punctures become larger and sparser along margins of eyes; facial fovea indistinct; gena slightly narrower than eye in lateral view, moderately shiny with fine and close to sparse punctures; pronotal collar roundly thickened, attenuated toward middle; mesoscutum moderately shiny with fine and sparse punctures; scutellum slightly convex, moderately shiny with larger and sparser punctures than those on mesoscutum; metanotum weakly convex and slightly shiny, with close punctures; mesopleuron moderately shiny with fine to moderate and dense to close punctures; propodeal TRN, OBL and lateral carinae indistinct, anterior portion of propodeal with transverse wrinkles, posterior portion with moderate and subcontiguous punctures; T 1 transverse lineolate-reticulate, shiny with minute and scattered punctures,T 2 and following terga with larger and closer punctures.

Pilosity: Hairs on vertex yellow, dense and short; hairs on apical margin of clypeus yellow and very sparse; hairs on mesoscutum white and particularly short; hairs on lateral metanotum longer; hairs on mesopleuron white and sparse; pronotal collar and pronotal lobe with short dense yellow hairs; hairs on T 1 extremely short and sparse, hairs on T 2 and T 3 white, short and sparse.

Terminalia: See Figs. 1–6View FIGURES 1 – 6. Apical lobe of S 7 reduced and without hairs. S 8 more or less rhombiform, apical process slender.
