Diagnosis.

BOTH SEXES (N = 5). Small-sized (4.00-5.75 mm). Head and mesosoma dark blue to blue-green. Fore wing hyaline. Body robust (mesonotum 1.26-1.33 × as long as wide). Eyes large (0.60-0.67 × as high as head) (Fig. 10h View Figure 10 ). Corona thick to medium (3.70-4.75 × as long as wide), structure continuous (Fig. 7h View Figure 7 ). Pronotum pentagonal with posterior part distinctly narrowing towards mesoscutum, with broadest part before midlength (Fig. 13h View Figure 13 ). Mesoscutellum normal to slender (0.64-0.80 × 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; 0.28-0.39), meoscutellum lineate in anterior third to half, rugulose in posterior half or two thirds (Fig. 16h View Figure 16 ). Propodeum large (0.18-0.23 × as long as mesoscutum) (Fig. 16h View Figure 16 ). Profemur usually medium to elongated (1.98-2.33 × as long as wide, only only 1 of 5 with profemur robust). Marginal vein medium (0.93-1.07 × as long as postmarginal vein).

FEMALE. Head round (1.30-1.41 × as high as long). Metasoma medium (0.47 × as long as body). Ovipositor short (0.13-0.14 × as long as metasoma) (Fig. 4h View Figure 4 ).

MALE. Head oval (1.53-1.54 × as high as long).

Taxonomic remarks.

Some (or maybe all) specimens described here as O. srilankiensis were probably those examined and mentioned by Bouček et al. (1978) and considered as O. ahoma . After careful examination they can be distinguished from the holotype of O. ahoma by several characters, for example, the very different body length (medium in O. ahoma , small in O. srilankiensis ), the body shape (slender in O. ahoma , robust in O. srilankiensis ), and the eye size (small in O. ahoma , large in O. srilankiensis ). Bouček et al. (1978) also mentioned the close resemblance of some specimens (including one from Pakistan that we were unable to locate) with "a European species", i.e., O. formosa . In fact, the new species is rather similar to O. formosa but can be distinguished from this by some characters, for example, fore wing hyaline ( O. srilankiensis ) vs. partly infumate ( O. formosa ), and propodeum large ( O. srilankiensis ) vs. propodeum usually medium ( O. formosa ) (see also diagnoses and key).
