Type material.

Holotype ♀, India: Rajasthan, Nagda Temple, 25 km N Udaipur Lake, 22. xi. 2002, A. Freidberg (CUMZ) . Paratype. 4 ♀, same data as holotype (2 in SMNHTAU, 2 in MNB) .

Diagnosis.

Uniformly brownish yellow but with stemmaticum and fore wing vein C + SC + R and pterostigma pale brown-yellow, second submarginal cell short with vein 3 RSa shorter that 2 RS (Fig. 16 B). Similar to Trigastrotheca carinata Ranjith, sp. nov. but stemmaticum black and T 5 relatively far shorter (Fig. 16 A cf. Fig. 6 C).

Description.

Holotype female. Length of body 5.5 mm, fore wing 3.9 mm. Head. Antenna with 38 flagellomeres. Terminal flagellomere acuminate. First flagellomere 1.2 × longer than 2 nd and 3 rd, the latter 1.5 × longer than wide. Width of head: width of face: height of eye = 2.5: 1.3: 1.0. Face with fine transverse striations laterally; with weak mid-longitudinal ridge. Inter-tentorial distance 1.8 × longer than tentorio-ocular distance. Malar suture impressed. Malar space 1.2 × as long as basal width of mandible. Antennal sockets strongly produced. Frons strongly impressed with a complete mid-longitudinal carina. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.0: 2.0. Mesosoma 1.4 × longer than high. Mesoscutum rugose; notauli not impressed except very short anterior part with few weak crenulations. Scutellar sulcus shallow, narrow, finely crenulate. Scutellum sparsely punctate without small pit medially behind sulcus. Median area of metanotum with complete mid-longitudinal carina. Propodeum largely smooth and shiny, faintly rugose antero-laterally; mid-longitudinal carina complete, not lamelliform, bordered narrowly by fine crenulations; posteriorly propodeum with short longitudinal carinae. Wings. Fore wing. Lengths of fore wing veins r-rs: 3 RSa: 3 RSb = 1.0: 1.2: 4.5. Lengths of vein 2 RS: 3 RSa: rs-m = 1.1: 1.0: 1.1. Base of hind wing glabrous. Legs. Lengths of fore femur: fore tibia: fore tarsus = 1.0: 1.1: 1.1. Lengths of hind femur: hind tibia: hind tarsus = 1.0: 1.2: 1.1. Claws with small acutely pointed basal lobe. Metasoma. T 1 1.7 × wider than long. T 2 0.9 × as long as T 3. T 1 coriaceous. TT 1–5 with coarse reticulate sculpture Second metasomal suture and basal grooves of TT 4 and 5 deep, strigose. T 5 with postero-lateral margin of convex, unevenly denticulate; medial protuberance acutely rounded. Coloration. Body mostly yellow except antenna, eye, stemmaticum, tarsi, ovipositor sheath black.
