Distribution.

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

Diagnosis.

Head (Fig. 22B-D ): GOI = 2.8-3.1; lower face 0.6-0.7 × as wide as high; clypeus almost flat in profile, its lower margin acute to subacute; mandible rather weakly twisted by 15-25°, moderately long, proximally tapered and distally approximately parallel sided, its outer surface without a diagonal structure; upper mandibular tooth 1.2-1.4 × as long as lower one; posterior ocellus almost touching eye; antenna with 52-65 flagellomeres and 20th flagellomere 1.7-2.3 × as long as wide.

Mesosoma (Fig. 22E ): mesopleuron punctate to longitudinally punctostriate; scutellum with lateral longitudinal carinae reaching posterior end and convergent posteriorly; metapleuron punctostriate; propodeum evenly rounded, its posterior area moderately reticulate, outer margin of propodeal spiracle not joining pleural carina by a ridge.

Wings (Fig. 22F ): fore wing with AI = 0.7-0.9, CI = 0.6-0.7, ICI = 0.4-0.6, SDI = 1.3-1.4; fore wing vein 1m-cu&M moderately sinuous, 2r&RS almost straight; fenestra and sclerites of discosubmarginal cell of fore wing as in Figure 22F ; fenestra of fore wing not very long and its anterodistal corner distinctly separated from proximal end of vein RS; proximal sclerite semicircular, isolated and not touching margin of fenestra, almost always (very) weakly pigmented; central sclerite absent; distal sclerite absent or vestigial; proximal corner of marginal cell of fore wing uniformly setose; vein 1cu-a antefurcal to M&RS by 0.2-0.3 × 1cu-a length.

Colour (Fig. 22 ): body including interocellar area entirely testaceous; wings hyaline.

Differential diagnosis.

Enicospilus pseudoconspersae is one of the most distinctive and easily distinguishable species among the Oriental species of Enicospilus on account of the characteristic isolated and weakly pigmented semicircular proximal sclerite (Fig. 22F ). There are no known morphologically similar species.
