Etymology
The species epithet “ shadaensis ” refers to Shada Al Ala, one of the localities where specimens were collected.

Description
Female (7 specimens)
B 19–21; F 12–13; ML 0.2; CT 1.2; POL1.0; FI 0.65; Fl1–2 1.6; AI 0.87; CI 0.3; ICI 0.5; SDI 1.2; NI 3.8.
COLOUR. Reddish brown overall including antennae and legs, with ivory yellow on vertex, orbits, lateral sides of mesoscutum (which are broad anteriorly, becoming very thin laterally, but not reaching end) scutellum, subalar prominence, two markings on upper and lower ends of mesopleuron, upper one distinctly larger, a large marking on lower part of metapleuron (just above hind coxa); metasoma with T1 entirely dark brown to black, T2 with lighter posterior margin, remaining metasomal tergites mostly light red to orange, blackish medially, last tergite reddish, with dark posterior margin; mandible reddish with black teeth; fore wing with dark to black pterostigma with yellow proximal corner, parastigma yellow, distal end of pterostigma pale brown, sclerites and wing venation dark brown.
HEAD. Mandible hardly twisted, parallel-sided, with black thin outer margin, upper tooth about 2.0 × as long as lower tooth, outer mandibular surface with dense fine pale setae, without groove on outer surface; clypeus superficially punctate, flat in profile, ventral margin truncate; labrum semicircular, about 0.3 × as high as wide; face 1.3 × as high as wide; gena constricted behind eyes; occipital carina complete and thin; ocelli relatively large, lateral one nearly touching eyes; antenna with 50 flagellomeres.
MESOSOMA. Pronotum normal, with deep transverse furrow; epicnemial carina more or less distinct, weak; postpectal carina only distinct laterally, interrupted or indistict medially; mesoscutum densely punctate-reticulate, notauli indistinct; scutellum smooth, impunctate, slightly longer than basal width, carinate to apex; mesopleuron and metapleuron densely punctate; basal transverse carina of propodeum weak, anterior area of propodeum nearly smooth, posterior area shallowly rugose.
WINGS. Disco-submarginal cell of fore wing with well developed fenestra, proximal sclerite triangular, dark brown to black; central sclerite totally absent; Rs+2 r slightly thickened ventrally at basal third, more or less straight; cu-a subopposite Rs & M by about 0.25 × length of cu-a; hind wing with 7 distal hamuli on R1.
LEGS. Fore tibia not spinose; claws with black teeth, denser and shorter basally.
METASOMA. Slender; T 2 in profile about 4 × as long as high; thyridium very shallow, linear basally and widened apically, slightly posterior to one third length of tergite.
Male (7 specimens)
B 23; F 16.
Resembles female except for the following: body more slender; antenna with 52 flagellomeres; ivory markings on meso- and metapleura are distinctly smaller in size. Otherwise very similar to female.
BOLD Identification Number
ABX3540.
Remarks
This species agrees completely with the key characters of Enicospilus sp. 4 in Gauld & Mitchell (1978). But compared to the full description, it differs in the following characters: antenna with 50 flagellomeres (in sp. 4 62–64 flagellomeres); alar sclerite resembles that of sp. 4 (Gauld & Mitchell 1978: fig. 379); the mesoscutal ivory margins do not extend the whole length of the mesoscutum (in G. & M. it extends along the whole margins of the mesoscutum); no central ivory marking could be seen on the mesopleuron of our specimen (in G. & M. a central marking is present); metapleuron with a posterior ivory marking (in G. & M. it is present centrally); T1 entirely black (not so in G. & M.).
Enicospilus shadaensis sp. nov. resembles E. pseudoculator sp. nov. but differs in the following characters: body dark reddish brown, metasoma patterned with bright red to orange (in pseudoculator sp. nov. lighter orange to brown, metasoma not patterned with red); proximal sclerite dark brown to black, triangular (in pseudoculator sp. nov. proximal sclerite bright red and dome-shaped); face narrow, 1.5 × as high as wide (in pseudoculator sp. nov. face subquadrate, 1.1 × as high as wide); CI> 0.2 (in pseudoculator sp. nov. CI <0.2); moderately large species (B> 27; F> 12) (pseudoculator sp. nov. smaller species (B <19, F <12)).
