Figs. 11–12

Material examined. Holotype: female, Hubei, Shennongjia Qianjiaping, 21.V.2012, Shi Kai, No 201204457 ( ZJUH).

Description. Female ( Fig. 11 ) holotype. Body length 5.8 mm, fore wing length 4.1 mm.

Head. Antenna with 30 flagellomeres; first flagellomere 1.1× longer than second flagellomere. Face ( Fig. 12E ) granulose. Clypeus ( Fig. 12E ) mat, slightly convex, apical margin slightly arched, thick medially. Malar space granulose, 0.45× basal width of mandible. Mandible with a very weak lamella, upper tooth slightly longer than lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 12F ) 1.5× ocello-ocular distance and 1.8× distance between median and lateral ocelli. Temple granulose, mat, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose dorsally, mat, trans-striate below. Mesoscutum ( Fig. 12G ) granulose, rugose in notaulic area anteriorly. Scutellum and metanotum granulose with scutellum rugose posteriorly. Mesopleuron ( Fig. 12B ) granulose, weakly trans-striate below tegula, speculum largely granulose, smooth and shiny medially. Metapleuron granulose. Propodeum ( Fig. 12C ) granulose; area basalis trapezoid; area superomedia confluent with area petiolaris, broadly and shallowly depressed, granulose; median and lateral longitudinal carinae obscure; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 12A ) areolet present and with a short stalk emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 2.0× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus inclivous, intercepted at lower 0.15.

Legs. Hind femur 4.3× longer than wide. Inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus. Tarsal claws pectinate basally.

Metasoma. First metasomal segment ( Fig. 12H ) round in cross-section of basal 0.3, with dorso-lateral carina and lateral groove shallow. First tergite 2.6× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.65× as long as first tergite, 1.1× longer than its apical width; thyridium round, its distance from basal margin of tergite equal to its diameter. Third tergite 0.7× as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.4× longer than hind femur, ovipositor ( Fig. 12D ) gradually upcurved.

Colour. Black. Mandible medially, palpi and tegula, yellowish brown; scape and pedicel blackish brown; fore and mid legs coxae and telotarsus brown, remainder of fore and mid legs yellowish brown; hind leg with coxa, trochanter, trochantellus, tibia extreme basally and apically, and tarsus brown, remainder of hind leg yellowish brown; metasoma entirely black.

Distribution. China (Hubei).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1977) to C. kamathi Gupta & Maheshwary, 1977 , but differs from the latter by having face granulose, interocellar distance 1.5× ocello-ocular distance, medio-longitudinal carina obscure, median depressed area not striate, first metasomal segment with dorsolateral carina and lateral groove present, and body color different.

Etymology. Name derived from “apacus” (Latin for “obscure”) and “carina” (Latin for “carina”), because its propodeal median and lateral longitudinal carinae are weakly developed.
