Coelichneumon (Exephanides) pseudoneotypus nov.sp.

Holotypus (): India W Meghalay 25 40 N 91 04 E, Nokrek Nat. Park, XII.1997, leg. Murzin (ZSM)

D e s c r i p t i o n of: Body length 15 mm. Flagellum strongly lanceolate, with 38 flagellomeres, first flagellomere (without anellus) 2.5x and second one 2.4x as long as wide, both flagellomeres together about 0.58x as long as the compound eye, about the 12th segment square, flagellomeres beyond the middle strongly attenuated, the widest about 2.5x as wide as long. Temple roundly narrowed behind the eye, seen from lateral 0.75x as wide as eye, at lower eye margin with scattered puncture. Distance of lateral ocelli to the eyes about 1.4x as long as their diameter. Frons almost smooth, face and clypeus with coarse puncture, intervals smooth and shining. Malar space about 0.7 times as long as the width of mandibular base. Hypostomal carina not elevated.

Mesosoma with whitish hairs. Sides of pronotum mainly with superficial puncture. Mesoscutum with coarse puncture, with wider intervals in the apical fifth. Mesopleurum, and metapleurum with rather dense and coarse puncture, shining, coxal carina strong. Scutellum slightly convex, slightly wider than long, without lateral carinae, with scattered puncture. Propodeum rounded, area superomedia hexagonal, wider than long, sculpture smoothened, costula behind the middle. Area superoexterna with some coarse puncture, area petiolaris with lateral carina, transversely striate. Coxa III punctured, with slightly elevated, small dark scopa of 1/6 of coxal length. Femur III with scattered puncture in the lower third, about 3.5x as long as high. Third tarsomere II about 1.4x as long as wide.

Areolet pentagonal, frontal distance of intercubiti about 2x their diameter, 2mcu in its middle. Nervulus postfurcal.

Metasoma strongly oxypygous and narrowed from the third tergite on. Postpetiolus strongly widened, dorsal carina not developed, median field with coarse puncture and some striae. Tergite 2 about 0.9x as long as wide. Gastrocoelus impressed. Thyridium transverse, large, about 0.9x as wide as the thyridial interval. Tergites 2-3 with coarse puncture, and strong striation covering the central 2/3 of tergites, tergite 4 with some basal striation, tergite 5 with superficial puncture. Seventh tergite longer than the sixth one. Seen from above ovipositor sheath about 0.5 times as long as the seventh tergite.

Colour: black. Ivory are stripe on flagellomeres 6-17, base of mandible, palps, clypeus except narrow median stripe, face except an heart-shaped black central mark, complete orbits, collare and upper margin of pronotum, propleurum apically, large longitudinal stripe on lower mesopleurum, subtegular ridge, scutellum except a median black stripe, postscutellum, apical band of postpetiole, large posterolateral transverse marks on tergi- tes 2-5, apical band of tergite 6, coxa and trochanters I-II, and ventral and dorsal spots on coxa III and trochanter III. Legs yellowish-red. Femur I caudally, and femora II-III apically infuscate, apical third to half of all tergites and tarsi I-II infuscate. Tarsus III creamyellow. Pterostigma blackish.

unknown.

R e m a r k: This taxon differs from Coelichneumon neotypus HEINRICH by a small but distinct scopa on coxa III and the colour pattern of the head: ivory are clypeus except an apical median black spot, face except an heart-like central black patch, and complete gena and orbits.
