Paratypes: 12.i.2012, 11 females, Seven females (6 on card and 1 on slide under five coverslips) with same data as in Holotype ( EDAU); EDAU /Enc4P1/2012 - EDAU / Enc4P7/2012, 4 females, yellow pan traps, grassy field, Annamalai University premises, Chidambaram (11.230 N & 79.410 E), coll. Rameshkumar & Palanivel (two females each with ZDAMU - HYM. CH.665 and NBAII - DNR / Reg. No. 1/3a/2012 & DNR / Reg.No. 1/3b/2012, Bengaluru ) .

Female: ( Image 1 ). Length, 1.3–1.7mm. (Holotype,

1.6 mm).

Colour: Head black with metallic violet luster; antennal scape yellow progressively darkening towards apex, apical one-fourth brown; pedicel yellowish-brown; flagellum dark brown. Pronotum and mesoscutum dark brown with metallic purplish luster; tegula largely and axilla dark brown; scutellum basally dark purple, gradually becoming green and then yellowish-green at apex; propodeum brown; mesopleuron dark brown. Forewing subhyaline with a broad longitudinal infuscate patch from proximal end of marginal vein to apex and also below parastigma; hindwing subhyaline. Legs with fore and mid coxae,trochanters and major part of femora dark brown; apices of femora and remainder of legs and whole of hind leg yellowish-brown. Metasoma largely yellowish with light brown tinge except the last tergite, dorso-lateral sides of first tergite, tip of hypopygium and exserted part of ovipositor sheath dark brown.

Head: ( Image 2 ) Head, in front view, slightly broader than high (570:530); frontovertex one-third head width; frontovertex with reticulate sculpture; setae on head, eye and malar space white; eye length 3.5× malar space; antennal scrobes not meeting dorsally; antennal toruli separated from each other by their own height and separated from mouth margin by less than their own length. Antenna ( Image 3 ) with scape cylindrical and 8.5× as long as broad; pedicel longer than F1; all funicle segments longer than broad; clava 3-segmented and apically rounded with 13 longitudinal sensillae, slightly shorter than preceding three funicle segments combined. Mandible tridentate.

Relative measurements (in microns): Head width, 570; height, 530; frontovertex width, 190; POL, 90; AOL, 50; OOL, 20; OCL, 40; eye height, 420; malar space, 120; antennal toruli width, 40; distance between toruli, 70; scape length, 340; scape width, 40.

Mesosoma: Mesoscutum with shallow squamiformreticulate sculpture; axilla and scutellum with very much deep vermiculate - reticulate sculpture; setae on mesoscutum white, setae on pronotum, axilla, and scutellum whitish with base light brown, a pair of long setae at apex of scutellum brown. Forewing 3.25× as long as wide (1300:400) ( Image 4 ); hind wing 5.4× as long as wide.

Relative measurements (in microns): Mesosoma length, 670; mesoscutum length, 290; scutellum length, 240; median length of propodeum, 80; fore wing length, 1300;width, 400; submarginal vein length, 480; marginal vein length, 140; post marginal vein length, 110; stigmal vein length, 60; hind wing length, 970; width, 180; mid tibia length, 610; mid tibial spur length, 160.

Metasoma: ( Image 5 ) Longer than mesosoma (850: 700); gasteral tergites with shallow reticulate sculpture (visible at higher magnifications); ovipositor exserted and 1.15× as long as mid tibial length, 4.3× as long as mid tibial spur.

Relative measurements (in microns): metasoma length, 850; last tergite length, 520; ovipositor length, 690; gonostylus length, 140.

Male: Unknown.

Variation: Colour variation is noted from gradual

darkening of pedicel and flagellum to complete dark brown. Similar colour variation is also noted in the apex of scape.

Host: Unknown.

Distribution: India: Tamil Nadu (Chidambaram).

Etymology: The species is named afer the chalcid

specialist, Dr. M. Hayat of Aligarh Muslim University, Aligarh, Uttar Pradesh. The name is noun in genitive case.

Comments: This new species is closer to Adektitopus

gordhi but differs in the following characters: forewing 3.25× as long as wide; distinct broad longitudinal infuscate patch / streak from level of proximal end of marginal vein to nearly the apex; head width 1.05× its height; ovipositor 1.15× as long as mid tibia length and coloration of legs, testaceous yellow with fore and mid coxae, femora except apices dark brown [In gordhi , fore wing slightly less than 3× as long as wide; fore wing hyaline, rarely with a faint longitudinal fuscous streak in apical half; head width 1.12× its height; ovipositor 1.33× as long as mid tibia length; legs honey yellow except fore coxa and largely mid coxa dark brown.].
