Distribution.

Diagnosis.

Head (Fig. 11B-D): GOI = 2.5-2.7; lower face 0.7-0.8 × as wide as high; clypeus almost flat in profile, its lower margin acute; mandible moderately twisted by 20-30°, moderately long, proximally tapered and distally almost subparallel sided, its outer surface without a diagonal structure; upper mandibular tooth 1.4-1.5 × as long as lower one; posterior ocellus (almost) touching eye; antenna with 58-62 flagellomeres and 20th flagellomere 1.7-1.9 × as long as wide.

Mesosoma (Fig. 11E): mesopleuron punctate dorsally and rather closely longitudinally punctostriate to striate ventrally; scutellum with lateral longitudinal carinae reaching anterior 0.8 or more and convergent posteriorly; metapleuron rather closely striate; propodeum declivous in profile, its posterior area concentrically striate, outer margin of propodeal spiracle not joining pleural carina by a ridge.

Wings (Fig. 11F): fore wing with AI = 0.8-1.4, CI = 0.5-0.6, ICI = 0.4-0.5, SDI = 1.4-1.5; fore wing vein 1m-cu&M almost evenly curved, 2r&RS weakly bowed centrally; fenestra and sclerites of discosubmarginal cell of fore wing as in Figure 11F; fenestra of fore wing not very long and its anterodistal corner distinctly separated from proximal end of vein RS; proximal sclerite not triangular, confluent with distal one, weakly to strongly pigmented; central sclerite weakly to strongly pigmented and sclerotised, linear and parallel to vein 2r&RS, positioned in central part of fenestra; distal sclerite weak; proximal corner of marginal cell of fore wing uniformly setose; vein 1cu-a subinterstitial to antefurcal to M&RS by less than 0.1 × 1cu-a length.

Colour (Fig. 11): body including interocellar area entirely testaceous; wings hyaline.

Differential diagnosis.

Enicospilus grammospilus is a very distinctive species on account of its characteristic shape of fore wing vein 2r&RS and sclerites as in Figure 11F. No similar species are recognised and is very easily distinguished from all other Enicospilus species by the characters summarised in the above diagnosis, such as concentrically striate posterior area of propodeum and characteristic shape of sclerites of discosubmarginal cell of fore wing (cf. Fig. 11F).
