Figs. 17–18
Material examined. Holotype: female, Shaanxi, Qingling, 8.VI.1998, Ma Yun, No 983546 (ZJUH).
Description. Female (Fig. 17) holotype. Body length 8.0 mm, fore wing length 5.1 mm.
Head. Antenna with 33 flagellomeres; first flagellomere 1.15× longer than second flagellomere. Face (Fig. 18E) granulose. Clypeus (Fig. 18E) finely granulose, slightly convex, apical margin almost truncated, blunt. Malar space granulose, 0.5× basal width of mandible. Mandible with lamella present basally, upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance (Fig. 18F) 1.2× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple granulose, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.
Mesosoma. Pronotum granulose, subpolished, trans-striate below. Mesoscutum (Fig. 18G) granulose, becoming rugose in notaulic area. Scutellum and metanotum granulose. Mesopleuron (Fig. 18B) granulose with small punctures, punctures denser in low half, trans-striate below tegula, speculum smooth and shiny, rugose above mesopleural fovea. Metapleuron (Fig. 18B) granulose. Propodeum (Fig. 18C) granulose, with area basalis trapezoid; area superomedia granulose; area petiolaris granulose medially and rugose laterally; area superomedia confluent with area petiolaris, moderately depressed; medio-longitudinal carina weak under costula, gradually strong apically; latero-longitudinal carina absent; propodeal spiracle small and oval.
Wing. Fore wing (Fig. 18A) areolet present and with a short stalk emitting 2m-cu vein from its basal part. Marginal cell short, distal part of surrounding vein 2.1× longer than proximal one. Vein 1cu-a opposite of M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus slightly inclivous, intercepted at lower 0.1 of its length.
Legs. Hind femur 5.5× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.
Metasoma. First metasomal segment (Fig. 18H) round in cross-section of basal 0.3, with dorso-lateral carina and lateral groove present. First tergite 3.3× longer than width of postpetiole. Metasoma entirely granulose except petiole. Second tergite 0.7× as long as first tergite, 2.4× longer than its apical width; thyridium oval, its distance from basal margin of tergite 2.0× of its length. From third tergite on strongly compressed. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.3× longer than hind femur, ovipositor (Fig. 18D) gradually upcurved.
Colour. Black. Mandible except teeth, scape and pedicel brown; palpi and tegula yellowish brown; fore and mid legs except coxae and telotarsus brown; hind leg coxa black, trochanter, extreme base of tibia and each tarsal segment apically brown, remainder of hind leg yellowish brown; metasoma from third tergites on laterally yellowish brown, remainder of metasoma black.
Distribution. China (Shaanxi).
Comparative diagnosis. This species is similar to C. multicinctus Gravenhorst, 1829, but differs from the latter by having fore wing areolet emitting 2m-cu vein from its basal part, first metasomal segment shorter than hind femur, third tergite 2.0× longer than its apical width, and mandible brown except teeth.
Etymology. Name derived from “collucatus” (Latin for “thin”), because this species looks thin.
