Coelichneumon (Coelichneumon) flavotibialis nov.sp. ( figs 13 , 33)

H o l o t y p u s (): "China-Shaanxi Lüeyang 18.5.00" (Linz).

D e s c r i p t i o n of: Body length 19 mm. Flagellum slightly lanceolate, tips broken off, first flagellomere (without anellus) 2.2x as long as wide, the second one 1.9x, both flagellomeres together about 0.63 as long as the compound eyes, the 13th or 14th flagellomere square, the widest ones 1.2x as wide as long. Temple roundly narrowed behind the eye. Distance of lateral ocellus to the eye about 1.3x as long as its diameter. Frons with scattered puncture, face punctured and granulated, clypeus punctured, smooth. Malar space about 0.6x as long as the width of mandibular base, temple wide, seen from lateral about 0.9x as wide as the compound eye, with very superficial punctures below.

Mesosoma with light brownish hairs. Notauli distinct at the frontal 1/5 of mesoscutum. Mesoscutum with rather scattered puncture, finely granulated but shining; mesopleurum punctured and smooth, metapleura with denser puncture and smooth, coxal carina strong. Scutellum slightly convex, about as long as wide, without lateral carinae, with scattered puncture. Propodeum rounded, area superomedia heart-shaped, about as long as wide, anterior transverse carina obsolete, costula clearly behind the middle; area petiolaris with transverse rugae. Coxa III densely punctured and granulated, with distinct scopa of 1/3 of coxal length. Femur III with superficial puncture, about 3.8x as long as high. Third segment of tarsus II about 1.5x as long as wide.

Areolet almost quadrangular, frontal distance of intercubiti about 0.5x their diameter, 2mcu reaching the middle of areolet. Nervulus strongly postfurcal.

Metasoma strongly oxypygous. Lateral fields of postpetiole about 0.7x as wide as median field, the latter with strong longitudineal striae. Thyridium strongly impressed, oblique, about 0.7x as wide as the thyridial interval. Tergites 2-3 coarsely and densely punctured and more or less longitudinally rugose-striate medially. Seen from above ovipositor sheath about 0.6x as long as the seventh tergite.

Colour: black. Yellowish are stripes on flagellomeres 8-15, basal spot on mandible, lab- rum, wide sides of clypeus, gena, wide facial and narrower frontal orbits confluent with the spot on vertex, collare and upper margin of pronotum, subtegular ridge, sides of scutellum, small spot on lower mesopleurum anterior of epicnemium, coxae I-II mainly, all trochanters and trochantelli, anterodorsal and apical-ventral spots on coxa III. Legs I- II yellowish in front. Femur II black in the basal half. Femur III black, its apex narrowly yellow. Tibia III and tarsus III completely yellow. Metasoma black, without bluish shine. Pterostigma blackish.

unknown.

R e m a r k: With its black mesoscutum, black metasoma, and yellow hind leg (except coxa), the new taxon resembles Coelichneumon chinicus HEINRICH , but the coxa III has a weak scopa and a yellow spot ventrodorsal, the femur II is black with an apical yellow spot on front, and the black coxa II is yellow in the apical half only.

D i s t r i b u t i o n: China.
