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 × 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 × as long as lower one; posterior ocellus almost touching eye; antenna with 56-62 flagellomeres and 20th flagellomere 2.0-3.0 × 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 × 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).
