Distribution.

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

Diagnosis.

Head (Fig. 6B-D): GOI = 2.5-3.2; lower face 0.6-0.8 × as wide as high; clypeus almost flat in profile, its lower margin acute; mandible moderately twisted by 30-40°, moderately long, evenly strongly tapered, its outer surface without a diagonal structure; upper mandibular tooth 1.2-1.3 × as long as lower one; posterior ocellus almost touching eye; antenna with 53-64 flagellomeres and 20th flagellomere 1.7-2.1 × as long as wide.

Mesosoma (Fig. 6E): mesopleuron densely punctate to closely longitudinally punctostriate; scutellum with lateral longitudinal carinae reaching posterior end and convergent posteriorly; metapleuron densely punctate; propodeum declivous, its posterior area moderately reticulate, outer margin of propodeal spiracle not joining pleural carina by a ridge.

Wings (Fig. 6F): fore wing with AI = 0.6-0.7, CI = 0.3-0.5, ICI = 0.7-0.8, SDI = 1.2-1.4; fore wing vein 1m-cu&M evenly curved, 2r&RS almost straight; fenestra and sclerites of discosubmarginal cell of fore wing as in Figure 6F; fenestra of fore wing not long and its anterodistal corner distinctly separated from proximal end of vein RS; proximal sclerite linear, separated from or vestigially confluent with distal one, weakly pigmented; central sclerite absent; distal sclerite present proximally, vestigial to moderately strong distally; 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. 6): body including interocellar area entirely testaceous; wings hyaline to slightly infuscate.

Differential diagnosis.

Enicospilus biharensis is similar to E. maruyamanus, E. nikami sp. nov., E. pudibundae, and E. transversus, but can be distinguished from E. maruyamanus, E. nikami sp. nov., and E. transversus by the evenly curved fore wing vein 1m-cu&M (Fig. 6F) (more or less sinuous in E. maruyamanus, E. nikami sp. nov., and E. transversus, e.g. as in Figure 19F), and from E. nikami sp. nov. and E. pudibundae by the proximally complete pectination of the hind tarsal claw (Fig. 2I) (proximally incomplete in E. nikami sp. nov. and E. pudibundae).
