Figs. 43–44
Material examined. Holotype: female, Xinjiang, Tianchi, 6.VII.1991, He Junhua, No 913429 (ZJUH).
Description. Female (Fig. 43) holotype. Body length 3.8 mm, fore wing length 2.8 mm.
Head. Antenna with at least 20 flagellomeres (apical segments missing); first flagellomere as long as second flagellomere. Face (Fig. 44E) granulose. Clypeus (Fig. 44E) with minute punctures, mat, not convex, apical margin truncated, sharp, thick medially. Malar space granulose, 0.5× basal width of mandible. Mandible with lamella indistinct, upper tooth equal to the length of lower tooth, tapered apically. Frons granulose, median carina absent. Vertex granulose. Interocellar distance (Fig. 44F) 1.5× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple swollen behind eye, mat. Occipital carina evenly arched, reaching hypostomal carina slightly above mandible base.
Mesosoma. Pronotum rugulose dorsally, polished, trans-striate below. Mesoscutum (Fig. 44G), scutellum and metanotum granulose. Mesopleuron (Fig. 44B) punctate, trans-striate below tegula, speculum smooth and shiny. Propodeum (Fig. 44C) granulose; area basalis triangular; area superomedia smooth and shiny, weakly rugulosegranulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, slightly depressed medially; latero-longitudinal carina developed but weak; propodeal spiracle small and round.
Wing. Fore wing (Fig. 44A) areolet present and with a moderate stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.8× longer than proximal one. Vein 1cu-a distad of M&RS by 0.2 of its length. External angles of second discal cell acute (70°). Hind wing with nervellus vertical, intercepted at lower 0.4 of its length.
Legs. Hind femur 4.6× longer than wide. Inner spur of hind tibia 0.45× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, its teeth weak.
Metasoma. First metasomal segment (Fig. 44H) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 2.5× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.8× as long as first tergite, 1.25× longer than its apical width; thyridium round, its distance from basal margin of tergite equal to its diameter. Third tergite as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.4× longer than hind femur, ovipositor (Fig. 44D) abruptly upcurved apically.
Colour. Black. Mandible except teeth, palpi and tegula, fore and mid trochanters and trochantellus, hind trochantellus yellow; scape and pedicel blackish brown; coxae brown; remainder of fore leg yellowish brown with telotarsus infuscated; mid femur basally, tibia apically and from first tarsomere 0.5 on brownish, remainder of mid leg yellowish brown; hind trochanter, femur, subbase and apex of tibia and from basal tarsomere 0.5 on brown, with hind trochantellus, tibia medially and basal tarsomere 0.5 yellowish brown; metasoma black with second and third segments somewhat brown.
Distribution. China (Xinjiang).
Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. rufigastor Gupta & Maheshwary, 1977, but differs from the latter by having clypeus truncated and thick medially, interocellar distance 1.5× ocello-ocular distance, mesopleuron and metapleuron punctate, and metasomal colour different.
Etymology. Name derived from “lobus” (Latin for “protuberance”), because its clypeus is thick medially and has a lobe-like protuberance.
