Diagnosis .

BOTH SEXES (N = 13). Small-sized (4.50-6.48 mm). Head and mesosoma blackish and coppery, with small dark green parts, never with blue. Fore wing hyaline. Head usually oval (1.42-1.59 × as high as long, with only 2 of 13 with head round). Eyes large (0.60-0.74 × as high as head) (Fig. 10e). Corona usually medium (3.8-6.0 × as long as wide, with only 1 of 10 with corona thick), structure continuous (Fig. 7e). Pronotum pentagonal with posterior part distinctly narrowing towards mesoscutum, with broadest part before midlength (Fig. 13e). Mesoscutellum normal to slender (0.55-0.85 × as long as wide), anterior margin hardly convex to convex (part anterior to imaginary transverse line connecting posterior margins of axillae less than or more than 1/3 of mesoscutellum length; 0.3-0.45), mesoscutellum densely lineate in anterior half to anterior two thirds, areolate in posterior half or third (Fig. 16e). Propodeum medium to large (0.12-0.21 × as long as mesoscutum) (Fig. 16e). Profemur robust to medium (1.82-2.15 × as long as wide). Marginal vein short (0.78-0.89 × as long as postmarginal vein).

FEMALE. Body robust to medium (mesonotum 1.29-1.41 × as long as wide). Metasoma short (0.40-0.45 × as long as body). Ovipositor short to rather long (0.14-0.18 × as long as metasoma) (Fig. 4e).

MALE. Body robust to slender (mesonotum 1.27-1.47 × as long as wide).
