Material examined. Holotype ♀ (on slide under four coverslips, slide No. EUL.222), INDIA: UTTAR PRADESH: Jalesar , 6.iii.2013, Coll. M. T. Khan & S.K. Ahmed. ( ZDAMU).

Diagnosis: Omphale litera Jamali & Zeya sp. nov. looks apparently similar to Omphale ecola Jamali & Zeya sp. nov. in having more or less similar body colour. However, it differs from O. ecola sp. nov. by the following characters: scape 4.2× as long broad; mid lobe of mesoscutum with 4 long and thick setae; fore wing with a broad infuscate band below marginal vein beyond speculum, extending to stigmal vein and posterior margin of disc; postmarginal vein as long as stigmal vein; ovipositor 2.1× as long as hind tibia. In O. ecola Jamali & Zeya sp. nov.: scape 5.5× as long broad; mid lobe of mesoscutum with 2 relatively short and thin setae; fore wing with a narrow infuscate band below below marginal vein beyond speculum extending to posterior margin of disc; postmarginal vein one 0.2× stigmal vein; ovipositor 1.5× as long as hind tibia.

Description: Female: Body length, 1.1 mm. Head with vertex and upper frons metallic green, lower frons pale yellow. Antenna brown to dark brown. Mesosoma pale yellow with metallic green reflection. Fore wing hyaline with a broad infuscate band below marginal vein beyond speculum, extending to stigmal vein and posterior margin of disc (Fig. 2E). Fore and mid legs, including, coxae pale white; hind leg with coxa, femur basally three-fourth and last tarsomere brown, except femur one-fourth apically, tibia and tarsomeres 1–3 pale white. Gaster metallic pale yellow.

Head (Fig. 2A), in frontal view, 1.3× as broad as high; vertex with 12 long setae; eye height 2.7× as long as malar space; scrobal grooves joining frontal groove separately; mandible with many teeth, with ventral two teeth are larger (Fig. 2B); clypeus rectangular, 2.6× as broad as high; antennal toruli situated at the level of lower eye margin. Antenna (Fig. 2C) with scape 4.2× as long as broad, 2.4× as long as pedicel; pedicel 1.7× as long as broad; pedicel + flagellum 2.7× as long as distance between eyes (58: 21); flagellum with 1 distinct anellus; Fu1 0.9× as long and 1.4 as broad as Fu2; Fu3 subequal to Fu4; clava 3.8× as long as broad; clava shorter than all funiculars individually.

Mesosoma (Fig. 2D) 1.2× as long as broad, almost smooth except with hexagonal reticulation on anterior part of mesoscutum; pronotum narrow, visible in dorsal view; mesoscutum shorter than mesoscutellum; notauli incomplete, present in anterior third; mid lobe of mesosctum with 4 long and thick setae; side lobe with 2 setae; axillae elongate, extending posteriorly more than half length of mesoscutellum; mesoscutellum longer than broad, with 2 long setae; dorsellum smooth, 0.2× as long as broad and 0.6× median length of propodeum; propodeal callus with 2 short setae. Fore wing (Fig. 2E) 2.3× as long as broad; admarginal setae 7 arising from marginal vein; redial cell setose; marginal vein + parastigma 1.6× as long as submarginal vein, 5.06 as long as stigmal vein; post marginal vein 0.8× stigmal vein; stigmal vein slender; longest marginal seta 0.2× maximum wing width. Hind wing (Fig. 2F) 5.6× as long as broad with apex pointed; longest marginal seta 0.7× maximum wing width.

Metasoma (Fig. 2G). Petiole 1.8× as broad as long; gaster distinctly longer than mesosoma; ovipositor occupying almost whole of gaster length, exserted beyond apex of gaster; ovipositor 2.1× as long as hind tibia.
