Beaver leg. (NHMUK) . Distribution. Afrotropical and Oriental regions ( Yu et al. 2016 ). Gauld and Mitchell (1981) recorded this species from Nepal. Diagnosis. Head (Fig. 15B-D ): GOI = 2.9-3.1; lower face 0.7-0.8 x as wide as high; clypeus moderately convex in profile, its lower margin acute; mandible weakly twisted by 10-25°, moderately long, evenly tapered, its outer surface with a diagonal setose groove between its dorsoproximal corner and base of mandibular apical teeth; upper mandibular tooth 1.3-1.4 x as long as lower one; posterior ocellus almost touching eye; antenna with 56-62 flagellomeres and 20th flagellomere 2.0-3.0 x as long as wide. Mesosoma (Fig. 15E ): mesopleuron punctate to longitudinally punctostriate; scutellum with lateral longitudinal carinae reaching posterior end and convergent posteriorly; metapleuron punctostriate; propodeum weakly declivous in profile, its posterior area moderately reticulate, outer margin of propodeal spiracle joining pleural carina by a ridge. Wings (Fig. 15F ): fore wing with AI = 0.4-0.6, CI = 0.4, ICI = 0.4-0.6, SDI = 1.2-1.4; fore wing vein 1m-cu&M almost evenly curved or very slightly sinuous, 2r&RS almost straight; fenestra and sclerites of discosubmarginal cell of fore wing as in Figure 15F ; fenestra of fore wing not very long and its anterodistal corner distinctly separated from proximal end of vein RS; proximal sclerite triangular, separated from distal one, strongly pigmented; central sclerite strongly pigmented, sclerotised, well-delineated D-shaped to semi-circular, positioned in almost mediodistal part of fenestra; distal sclerite absent proximally and more or less strong distally; proximal corner of marginal cell of fore wing uniformly setose; vein 1cu-a antefurcal to M&RS by 0.1-0.3 x 1cu-a length. Colour (Fig. 15 ): body including interocellar area entirely testaceous; wings hyaline. Differential diagnosis. Enicospilus laqueatus , E. pseudoantennatus , E. vestigator , and E. tripartitus share similar fenestra, sclerites, and fore wing venation (e.g. Figs 15F , 21F , 26F ). However, E. laqueatus can be readily separated from E. pseudoantennatus , E. vestigator , and E. tripartitus by a diagonal setose deep groove of the outer surface of the mandible between its dorsoproximal corner and base of mandibular apical teeth (outer mandibular surface without a distinct diagonal setose deep groove in E. pseudoantennatus , E. vestigator , and E. tripartitus , as in e.g. Figure 2C ).
