Figs. 79–80

Material examined. Holotype: female, Shaanxi, Foping, Liangfengya, 30.VII.2013, Tan Jiangli , No 201303440 ( ZJUH).

Description. Female ( Fig. 79 ) holotype. Body length 4.8 mm, fore wing length 3.2 mm.

Head. Antenna with at least 18 flagellomeres (apical segments missing); first flagellomere 1.2× longer than second flagellomere. Face ( Fig. 80D ) granulose, weak laterally. Clypeus ( Fig. 80D ) granulose, almost truncated apically. Malar space mat, 0.7× basal width of mandible. Mandible with a weak lamella, upper tooth equal to the length of lower tooth. Frons granulose-punctate, median carina present. Vertex granulose. Interocellar distance ( Fig. 80E ) 1.0× ocello-ocular distance and 1.4× distance between median and lateral ocelli. Temple nearly smooth, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose dorsally, subpolished, trans-striate below. Mesoscutum ( Fig. 80F ) granulose, becoming rugose in notaulic area. Scutellum granulose, becoming rugose posteriorly. Metanotum granulose. Mesopleuron ( Fig. 80B ) granulose with sparse punctures, trans-striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 80B ) granulose. Propodeum ( Fig. 80C ) with area basalis trapezoid; area superomedia granulose, subpolished; area petiolaris rugose; area superomedia confluent with area petiolaris, not depressed medially; median carina weakly developed under costula, becoming stronger posteriorly; latero-longitudinal carina absent; propodeal spiracle small and round.

Wing. Fore wing ( Fig. 80A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 1.7× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (60°). Hind wing with nervellus slightly inclivous, intercepted at lower 0.3.

Legs. Hind femur 4.2× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws nearly not pectinate, teeth very weak basally.

Metasoma. First metasomal segment ( Fig. 80G ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 3.3× longer than width of postpetiole. Second tergite as long as first tergite, 2.0× longer than its apical width; thyridium oval, its distance from basal margin of tergite 3.0× its diameter. Third tergite 1.4× longer than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.4× longer than hind femur, ovipositor gradually upcurved.

Colour. Black. Mandible except teeth, palpi and tegula yellowish brown; scape and pedicel blackish brown; fore and mid legs with trochanters, trochantellus and coxae apically yellow, coxae basally and apical tarsus brown, remainder of fore and mid legs yellowish brown; hind leg with coxa blackish brown, trochanter, trochantellus, tibia subbasally and apically infuscated, tarsus brown, remainder of hind leg yellowish brown; metasoma from third tergite on laterally yellowish brown, remainder of metasoma black.

Distribution. China (Shaanxi).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. manaliensis Gupta & Maheshwary, 1977 , but differs from the latter by having face granulose, interocellar distance equal to ocello-ocular distance, area petiolaris rugose, and scape and pedicel blackish brown.

Etymology. This species is named in honour of Prof. Jiangli Tan, the collector of the holotype.
