Figs. 37–38

Material examined. Holotype: female, Zhejiang, Hangzhou Nangaofeng, 5.VII.2003, Chen Xuexin, No 20056130 ( ZJUH).

Description. Female ( Fig. 37 ) holotype. Body length 6.8 mm, fore wing length 4.2 mm.

Head. Antenna with 33 flagellomeres; first flagellomere 1.2× longer than second flagellomere. Face ( Fig. 38E ) granulose. Clypeus ( Fig. 38E ) granulose punctate, slightly convex, apical margin arched, blunt. Malar space granulose, 0.3× basal width of mandible. Mandible with lamella, with upper tooth equal to the length of lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 38F ) 1.3× ocello-ocular distance and 1.6× distance between median and lateral ocelli. Temple not swollen behind eye, mat. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum granulose dorsally with minute punctures, trans-striate below. Mesoscutum ( Fig. 38G ) granulose, becoming rugose in notaulic region. Scutellum granulose, becoming rugose posteriorly. Metanotum granulose-rugose. Mesopleuron ( Fig. 38B ) granulose-punctate, trans-striate below tegula, speculum smooth and shiny. Propodeum ( Fig. 38C ) granulose; area basalis trapezoid; area superomedia rugulose; area petiolaris transstriate; area superomedia confluent with area petiolaris, slightly depressed medially; all carina strong; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 38A ) 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 opposite M&RS. External angles of second discal cell acute (65°). Hind wing with nervellus inclivous, intercepted at lower 0.25 of its length.

Legs. Hind femur 4.8× longer than wide. Inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. First metasomal segment ( Fig. 38H ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. Postpetiole and second tergite granulose. Second tergite 0.8× as long as first tergite, 1.8× longer than its apical width; thyridium oval, its distance from basal margin of tergite 2.0× its length. Third tergite length equal to its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.5× longer than hind femur, ovipositor ( Fig. 38D ) gradually upcurved.

Colour. Black. Mandible medially, palpi and tegula yellow; scape and pedicel yellowish brown in front, brown dorsally; fore leg yellow except coxa basally brown; mid leg yellow except coxa basally and apical tarsi brown; hind coxa black, femur orange yellow, telotarsus brown, remainder of hind leg yellow; metasoma with first tergite and second tergite except apically black, second tergite apically yellowish brown, from third tergite on brown.

Distribution. China (Zhejiang).

Comparative diagnosis. This species is similar to C. anatolus sp. nov., but differs from the latter by having malar space 0.35× basal width of mandible, mesopleuron granulose-punctate, propodeal carina strong, fore and mid coxae apically yellow, hind tarsus with only telotarsus brown, and metasoma not entirely black.

Etymology. Name derived from “galbus” (latin for “yellow”) and “pedis” (Latin for “foot”), because its legs are largely yellow.
