Distribution.

Australasian and Oriental regions ( Yu et al. 2016). Gauld and Mitchell (1981) recorded this species from Nepal.

Diagnosis.

Head (Fig. 14B-D ): GOI = 2.8-3.1; lower face 0.7 × as wide as high; clypeus moderately convex in profile, its lower margin subacute to blunt; mandible moderately twisted by 20-30°, moderately long, evenly tapered, its outer surface without a diagonal structure; upper mandibular tooth 1.4-1.6 × as long as lower one; posterior ocellus close to eye; antenna with 63-66 flagellomeres and 20th flagellomere 2.1-2.3 × as long as wide.

Mesosoma (Fig. 14E ): mesopleuron entirely closely to rather coarsely longitudinally striate; scutellum with lateral longitudinal carinae reaching anterior 0.8 or more and convergent posteriorly; metapleuron rather coarsely striate to strigose; propodeum weakly declivous, its posterior area coarsely reticulate to concentrically striate, outer margin of propodeal spiracle joining pleural carina by a ridge.

Wings (Fig. 14F ): fore wing with AI = 0.4-0.5, CI = 0.2-0.3, ICI = 0.5-0.7, SDI = 1.1-1.3; fore wing vein 1m-cu&M moderately sinuate, 2r&RS almost straight; fenestra and sclerites of discosubmarginal cell of fore wing as in Figure 14F ; fenestra of fore wing not very long and its anterodistal corner distinctly separated from proximal end of vein RS; proximal sclerite almost triangular, confluent with distal one, strongly pigmented; central sclerite strongly pigmented and sclerotised, linear and parallel to vein 2r&RS, positioned in anterodistal part of fenestra; distal sclerite present proximally and vestigial to absent distally; proximal corner of marginal cell of fore wing uniformly setose; vein 1cu-a antefurcal to M&RS by 0.1-0.2 × 1cu-a length.

Colour (Fig. 14 ): body including interocellar area entirely testaceous; wings hyaline.

Differential diagnosis.

Enicospilus kanshirensis is most similar to E. flavicaput but can be distinguished from it by the stouter central sclerite (Fig. 14F ) (central sclerite slender in E. flavicaput as in Figure 8F ), and smaller body size (i.e. fore wing length less than 15.0 mm in E. kanshirensis but more than 17.0 mm in E. flavicaput ).
