Figs. 19–20

Material examined. Holotype: female, Guizhou, Daozhen Dashahe, 18.VIII.2004, Wu Qiong, No 201505028 ( ZJUH) . Paratype: 1 male, Guizhou, Daozhen Dashahe, No 201503196 .

Description. Female ( Fig. 19 ) holotype. Body length 5.7 mm, fore wing length 4.3 mm.

Head. Antenna with 32 flagellomeres; first flagellomere 1.1× length of second flagellomere. Face ( Fig. 20E ) granulose-punctate. Clypeus ( Fig. 20E ) sparsely punctate, polished, slightly convex, apical margin slightly curved. Malar space granulose, 0.6× basal width of mandible. Mandible with a very weak lamella. Frons granulose-punctate, median carina absent. Vertex granulose. Interocellar distance ( Fig. 20F ) 1.8× ocello-ocular distance and 2.0× distance between median and lateral ocelli. Temple granulose, mat. Occipital carina evenly arched, reaching hypostomal carina before mandible base.

Mesosoma. Pronotum punctate dorsally, trans-striate below. Mesoscutum ( Fig. 20G ) granulose-punctate, rugose on notaulic area anteriorly. Scutellum punctate, rugose posteriorly. Metanotum rugose-punctate. Mesopleuron ( Fig. 20B ) punctate, trans-striate below tegula, speculum smooth and shiny. Propodeum ( Fig. 20C ) smooth and compact; area basalis trapezoid; area superomedia nearly smooth, shiny, with few small punctures; area petiolaris trans-striate; area superomedia confluent with area petiolaris, not depressed medially; all carina strongly developed; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 20A ) areolet present and with a moderate 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 slightly distad of M&RS. External angles of second discal cell acute (70°). Hind wing with nervellus intercepted at lower 0.1 of its length.

Legs. Hind femur 4.1× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws strongly pectinate.

Metasoma. First metasomal segment ( Fig. 20H ) round in cross-section of basal 0.3, with dorso-lateral carina and lateral groove very weak. Postpetiole and second tergite granulose, subpolished. Second tergite 0.6× as long as first tergite, 0.8× as long as its apical width; thyridium round, its distance from basal margin of tergite 1.5× its diameter. Third tergite 0.55× as long as its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.8× longer than hind femur, ovipositor ( Fig. 20D ) gradually upcurved.

Colour. Black. Mandible medially and palpi, yellowish brown; tegula yellow; scape and pedicel brown; fore and mid coxae and apical tarsal segments brown, remainder of fore and mid legs yellowish brown; hind leg coxa and trochanter blackish brown, tarsus brown, remainder of hind leg yellowish brown; metasoma black with second and third tergites somewhat blackish brown basally.

Male. Essentially same as female.

Distribution. China (Guizhou).

Comparative diagnosis. This species is similar to C. hei sp. nov., but differs from the latter by having pronotum punctate dorsally, metanotum rugose-punctate, propodeal carina strongly developed, thyridium away from basal margin of tergite 1.5× its diameter, and metasoma with second and third tergites somewhat blackish brown basally.

Etymology. Name derived from “concretus” (Latin for “thick”), because its propodeum is compact.
