Distribution.

Oriental region ( Yu et al. 2016). Newly recorded from Nepal.

Diagnosis.

Head (Fig. 28B-D View Figure 28 ): GOI = 3.0-3.2; lower face 0.6-0.7 × as wide as high; clypeus slightly convex in profile, its lower margin acute; mandible weakly twisted by 10-20°, moderately long, proximally tapered and distally more or less parallel sided, 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 58-61 flagellomeres and 20th flagellomere 2.6-2.7 × as long as wide.

Mesosoma (Fig. 28E View Figure 28 ): mesopleuron punctate to rather coarsely longitudinally striate; scutellum with lateral longitudinal carinae reaching posterior end and convergent posteriorly; metapleuron rather coarsely striate; propodeum evenly weakly rounded, its posterior area more or less coarsely irregularly wrinkled with strong posterior transverse carina laterally, outer margin of propodeal spiracle joining pleural carina by a ridge.

Wings (Fig. 28F View Figure 28 ): fore wing with AI = 0.5, CI = 0.3-0.4, ICI = 0.4-0.5, SDI = 1.4-1.5; fore wing vein 1m-cu&M very slightly sinuous, 2r&RS almost straight; fenestra and sclerites of discosubmarginal cell of fore wing as in Figure 28F View Figure 28 ; fenestra of fore wing very long and its anterodistal corner very close to proximal end of vein RS; proximal sclerite triangular, confluent with distal one, strongly pigmented; central sclerite moderately pigmented and sclerotised, ill-delineated semicircular to oval, its major axis parallel to distal margin of fenestra, positioned in very distal and slightly anterior part of fenestra; distal sclerite entirely moderately pigmented; proximal corner of marginal cell of fore wing uniformly setose; vein 1cu-a antefurcal to M&RS by 0.1 × 1cu-a length.

Colour (Fig. 28 View Figure 28 ): body entirely black with pale yellow patterns, interocellar area not infuscate; wings hyaline but fore wing with three strongly infumate areas around anterocentral part of discosubmarginal cell, proximal part of second discal cell, and central part of marginal cell.

Differential diagnosis.

Gauld and Mitchell (1981) suggested that E. zebrus is related to the E. signativentris species-group and very close to E. biumbratus (Morley, 1912) on body and wing colour pattern as well as other characters, but E. zebrus is distinguished from E. biumbratus by many characters, such as the longer fore wing fenestra (Fig. 28F View Figure 28 ), smaller and semicircular to oval central sclerite (Fig. 28F View Figure 28 ), etc.
