Diagnosis

B 18–19; F 13; AI 0.6; ICI 0.52; CI 0.46; SDI 1.3; NI 1.8; ML 0.46; CT 1.7; POL 0.38; OOL 0.38; FI 0.5; Fl1–2 1.6; Fl20 3.0.

Body bright orange overall, with white on vertex, posterior border of eye and orbits just above emargination; metasomal T5 and T 6 in profile with black ventrally, ovipositor sheath and claws black, antennae dark brown, pterostigma yellow bordered with black above and behind; mandible twisted, with upper tooth 1.25 × as long as lower tooth; clypeus convex in profile, ventral margin in-turned; face 1.2 × as high as wide; antenna short, with 47 flagellomeres; mesopleuron puncto-striate, metapleuron punctate; basal transverse carina of propodeum distinct but weak, anterior area finely and shallowly punctate, posterior area reticulate; proximal sclerite triangular; central sclerite fully sclerotized; hind wing with 5 distal hamuli on R1; fore tibia sparsely spinose.

Material examined

SAUDI ARABIA: 1 ♀, Shada Al Ala (Al Baha), light trap 2, 27 Jan. 2015, leg. Al Dhafer et al. ( KSMA).

Remarks

This species closely resembles E. bicoloratus in almost all alar indices, the puncto-striate mesopleuron, the punctate metapleuron and the black apex of the metasoma. However, it differs from E. bicoloratus in the following: lower face 1.2 × as long as broad (in E. bicoloratus 1.4 × as long as broad); antennae relatively short, with 47 flagellomeres (in E. bicoloratus with 50–56 flagellomeres); hind wing with 5 distal hamuli on R1 (in E. bicoloratus with 5–7 distal hamuli on R1).

Distribution

Saudi Arabia.
