Diagnosis
Penultimate segment of antenna 2.2× as long as wide; mesoscutum densely evenly punctate, in lateral lobes presence of smooth area near tegula; notauli indicated by dense punctations; scutellum sparsely punctate in anterior half, punctation dense in posterior half (Fig. 1C); pterostigma 4.0× as long as wide, light brown; vein 1–R1 1.4 × as long as pterostigma, 3.0× as long as distance from end of vein 1–R1 to tip of radial cell (Fig. 1D); third tergite median length 0.7 × as long as second tergite (Fig. 1E).
Etymology
The name is derived from the Latin ‘ elongata ’, meaning ‘elongate’, and referring to the second metasomal tergite, which is longer than third tergite, while in the closely related species, Cotesia ruficrus (Haliday, 1834), it is shorter than the third tergite.

Comment
In the keys provided by Nixon (1974), Papp (1986) and van Achterberg & Polaszek (1996), Cotesia elongata sp. nov. runs close to Cotesia ruficrus (Haliday, 1834); it can, however, be separated from the latter by the following characters: (1) penultimate segment of antenna 2–2.2 (–2.3) × as long as wide vs 1.5 and 1.7 × in Nixon (1974) and van Achterberg & Polaszek (1996), respectively, (2) third tergite 0.7–0.8 × as long as second tergite (Fig. 1E) vs 1.2–1.4 in Papp (1986).
The new species can be included in the identification key of Cotesia compiled by Nixon (1974), which is modified below:
14. Antenna short, rather thick, preapical segment about one-and-a-quarter× as long as wide; legs dark brownish or obscurely brownish yellow throughout; mesopleuron anterior to and ventral to sternaulus, very shiny and with sharp discrete punctation ..................... C. amabilis (Nixon, 1974)
– Antenna longer and decidedly thin.................................................................................................A
A. Preapical segment of antenna fully one-and-a-half× as long as wide; mesopleuron anterior to and ventral to sternaulus, tending to be dull and evenly rugose................... C. ruficrus (Haliday, 1834)
– Preapical segment of antenna 2–2.2 (–2.3) × as long as wide; mesopleuron anterior to and ventral to sternaulus, tending to be punctate ...................................... C. elongata Zargar & Gupta sp. nov.
The new species can be included in the identification key of Cotesia compiled by Papp (1974), which is modified below:
10. First tergite at most as long as wide at hind, usually slightly shorter; second tergite slightly shorter than, or sometimes as long as third tergite; head in dorsal view somewhat less rounded behind eyes; hind coxa always reddish yellow................................................. C. kariyai (Watanabe,1937)
– First tergite usually slightly longer than wide at hind ....................................................................A
A. Second tergite one-fourth to one-fifth shorter than third tergite; third tergite usually more or less and fourth tergite less usually with yellow to reddish yellow pattern; tegulae yellow to vivid yellow .................................................................................................... C. ruficrus (Haliday, 1834)
– Second tergite 1.2–1.3 × as long as third tergite; third and fourth tergite yellowish brown (Fig. 1E); tegulae yellow......................................................................... C. elongata Zargar & Gupta sp. nov.
