(figures 2, 66, 74, 75, 77)

Diagnosis

Funicular segment 0.8× as long as clava (figure 66); female scape strongly flattened and wide (figure 66); frons with a blunt transverse edge in front of anterior ocellus (figure 74); with a fovea just in front of anterior ocellus and with a groove in front of fovea (figure 74); mid lobe of mesoscutum with a strong median groove (figure 2); submarginal vein with two setae; propodeum with a strong and complete median groove (figure 2); petiole 1.6× as long as wide, with an anterodorsal shield (figure 2); female with first gastral tergite medially extended backwards and rounded (figure 2).

Female (length of body =1.8–2.0 mm)

Colour. Scape yellowish brown with dark ventral and dorsal edges; pedicel dark yellowish brown with base darker; flagellum dark with apical claval segment paler. Frons yellowish brown with malar space and mouth area darker. Vertex dark brown, paler laterad to posterior ocelli. Mesoscutum golden-green, with or without purple tinges on side lobes, and with a small yellowish brown non-metallic stripe separating mid lobe from side lobes. Scutellum predominantly dark, median smooth area metallic bluish purple with posterior margin yellowish brown. Propodeum goldengreen, with purple tinges laterally. Legs ± yellowish brown, mid coxa, fore and mid femora and hind tibia darker. Fore wing hyaline with surface just below base of marginal vein strongly infuscate. Petiole yellowish brown. Gaster dark and shiny, with weak metallic tinges.

Head. Antenna as in figure 66. HE/MS/MO=2.2/1.0/1.4. Frons with weak small meshed reticulation, meshes transverse. Vertex smooth and shiny in front of vertexal suture, behind suture with strong small meshed reticulation and ± wrinkled. POL/OOL/POO: 33.0/18.0/1.0. Occipital margin rounded. WH/WT =1.3.

Mesosoma . Anterior one-fifth of mid lobe of mesoscutum with strong reticulation, remaining parts of mid lobe and side lobes with very weak engraved reticulation and shiny. Scutellum 0.7× as long as wide, laterally with very strong reticulation, a median triangle is smooth and shiny. Dorsellum wide, flat, smooth and shiny. TPS distinctly curved. Fore wing with three to seven admarginal setae; submarginal vein with two setae; LW/LM/HW: 2.0/1.2/1.0; PM/ST =0.5. Propodeum smooth and shiny, with a complete median groove.
