Dolichogenidea uru Rousse et Gupta , sp. nov.

( Fig. 12 c–d)

Diagnosis. Mesopleuron almost entirely polished but epicnemium punctate. Mesoscutum densely punctate basally, almost smooth apically to tegulae. Propodeal areola wide and very strong. Hind coxa entirely smooth. Tergum 2 wide a median transverse row of punctures. Females with antenna short, flagellomere 2 shorter than flagellomere 1 and flagellomere 15 quadrate.

Color. Head and mesosoma black, but flagellum testaceous, palpi pale yellow, mandible yellowish orange and clypeus dark reddish. Legs yellowish orange but all coxae brownish testaceous and trochanters and trochantelli whitish. Tergum 1 and often 2 black, laterotergites 1–2 pale yellow, the following tergites reddish-testaceous. Wings hyaline, venation light brown.

Description.

FEMALE (7 specimens). B: 2.4; A: 2.0; L: 2.9 (2.7–3.0).

Head. Moderately punctate. Clypeus not separated from face dorsally, its ventral margin truncate. Face and clypeus punctate, punctuation sparser on clypeus. H i: 0.8; EH i: 0.5; C i: 3.5; Fl 1i: 2.9; Fl 2i: 1.9; FL1– 2 i: 1.4; Fl 15i: 1.1; Fl 16i: 1.7; OO i: 2.0; IO i: 1.3.

Mesosoma . Sparsely setose on punctate areas. Pronotum polished, upper and lower furrows crenulate, moderately deep. Mesopleuron almost polished with a narrow moderately dense punctate area on epicnemium. Sternaulus deeply impressed, smooth. Metapleuron smooth with some vertical weak striations on apical half. Mesoscutum densely punctate anteriorly, punctures rather large, punctuation progressively sparser toward apex, mesoscutum smooth beyond tegulae. Scuto-scutellar suture deep and wide, crenulate. Scutellum almost polished.

MSC i: 0.9. Propodeum coarsely punctate rugose, strongly decurved beyond costulae. Carination very strong. Areola complete, wide, pentagonal, apically truncate and basally petiolate to base of propodeum. Costulae curved backward. Fore wing. R1/Pl i: 1.0; r/Pw i: 0.8; r/2Rs i: 1.0. Hind wing. Hind margin of vannal lobe regularly rounded and setose. Legs. Hind coxa short, entirely polished. Hind femur rather swollen. Cx/T 1i: 1.2; F i: 3.3.

Metasoma. Tergum 1 strongly curved in profile view, its lateral margins sub-parallel in profile view but basally constricted, mid-longitudinally bulging, apical margin slightly concave, surface coarsely aciculo-punctate. Tergum 2 transverse with basal margin centrally pointed forward and apical margin slightly convex, surface polished but a median transverse row of shallow punctures. Hypopygium large, slightly protruding beyond metasomal apex, medially desclerotised. Ovipositor large and regularly decurved, sheath setose all along. T1a i: 1.3; T1b i: 2.2; T1/ T 2i: 4.0; T2a i: 0.3; T2b i: 0.3; T2/T 3i: 0.5; OT i: 0.9.

MALE (2 specimens). B: 2.3; A: 3.0; L: 2.6 (2.6–2.8). Antenna longer and more slender, flagellomere 2 as long as flagellomere 1 and flagellomere 15 longer than wide, otherwise similar to female. Fl 1i: 2.9; Fl 2i: 2.9; FL1– 2 i: 1.0; Fl 15i: 2.2; Fl 16i: 2.4.
