COLOUR. Reddish brown overall, including antennae and legs, with profuse white on the following: head (except a narrow middle area just between and beneath antennal bases to base of clypeus, as well as around clypeus and occiput), lateral border of mesoscutum as well as two very thin lines in middle, tegula, axilla, scutellum, anterior border of pronotum (interrupted medially), two large markings on lateral side of pronotum, subalar prominence, an elongate oval marking postero-laterally of propodeum, two large markings forming together an inverted L-shaped marking on upper side of mesopleuron and a small rounded one on its lower area just above base of mesocoxa, a transverse band at upper side of metapleuron and a small rounded marking at lower area just above metacoxa, metasoma with ivory markings laterally on T3–T7. Fore wing with yellowish pterostigma is bordered above and behind by black, wing veins black, sclerites black.

HEAD. Mandible hardly twisted, with slightly ridged and dark external margin and with two subequal to equal-sized teeth; labrum semicircular, about 1.3 × as broad as long; clypeus flat in profile, ventral margin straight to truncate; face subquadrate, 1.1 × as high as wide; gena moderately swollen behind eye; occipital carina complete and thin; antenna short, with 44 flagellomeres.

MESOSOMA. Pronotum normal; mesoscutum nearly smooth and shiny; mesopleuron closely punctate, metapleuron puncto-striate; epicnemial carina distinct to level of ventral corner of pronotum; postpectal carina distinct and complete; notauli indistinct; scuto-scutellar groove strigated; scutellum smooth, carinate to apex; transverse basal carina of propodeum weak but distinct, propodeum nearly smooth to transversely shagreened, superficially wrinkled posteriorly.

WINGS. Disco-submarginal cell of fore wing with well developed fenestra, proximal sclerite triangular to dome-shaped, central sclerite small circular and uniformly sclerotized; Rs+2 r very slightly thickened medially, more or less straight; hind wing with 4 distal hamuli on R1.

LEGS. Fore tibia not spinose.

METASOMA. Slender, T 2 in profile 5 × as long as high; thyridium ellipsoid, shallowly dilineated extending along anterior third of T2 laterally; ovipositor short, hardly extending beyond abdominal extremity.

Male (3 specimens)

Similar to female.

BOLD Identification Number

Remarks

This species resembles E. oculator , but differs from it by the following combination of characters: in E. mirabilis sp. nov. clypeus almost ivory (except laterally and ventrally) (in E. oculator clypeus ivory only ventrally); propodeum and metapleuron each with a large oval ivory marking (in oculator no ivory markings on metapleuron and propodeum), metasoma with ivory markings (in oculator metasoma without ivory markings); mandibular teeth subequal (in oculator upper tooth 1.5 × as long as lower tooth); posterior area of propodeum superficially or shallowly finely wrinkled (in oculator coarsely striate); central sclerite uniformly sclerotized (in oculator central sclerite weakly sclerotized proximally); Fl20 <1.7 (in oculator Fl 20> 1.7); hind wing with 4 distal hamuli on R1 (in oculator with 5 distal hamuli on R1).

Distribution
