Figs. 1–2
Material examined. Holotype: female, Shaanxi, Hanzhong Liubaxian, 20.VII.2013, Tu Binbin, No 201308253 (ZJUH).
Description. Female (Fig. 1) holotype. Body length 4.5 mm, fore wing length 3.5 mm.
Head. Antenna with 23 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face (Fig. 2E) granulose. Clypeus (Fig. 2E) granulose, slightly convex, apical margin almost truncated, 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. 2F) 1.2× ocello-ocular distance and 1.8× distance between median and lateral ocelli. Temple granulose, subpolished, not swollen behind eyes. Occipital carina evenly arched, reaching hypostomal carina above mandible base.
Mesosoma. Pronotum granulose dorsally, mat, trans-striate below. Mesoscutum (Fig. 2G) granulose, notauli indistinct. Scutellum and metanotum granulose. Mesopleuron (Fig. 2B) granulose, weakly trans-striate below tegula, speculum smooth and shiny. Metapleuron (Fig. 2B) granulose. Propodeum (Fig. 2C) with anterior transverse carina far from base, area basalis triangular, long and narrow; area superomedia granulose, polished; area petiolaris rugose; area superomedia confluent with area petiolaris, slightly depressed; all carina distinctly developed; propodeal spiracle small and round.
Wing. Fore wing (Fig. 2A) 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 (75°). Hind wing with nervellus slightly inclivous, intercepted at lower 0.2.
Legs. Hind femur 4.6× longer than wide. Inner spur of hind tibia 0.5× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.
Metasoma. First metasomal segment (Fig. 2H) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. First tergite 2.3× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.9× as long as first tergite, 1.8× longer than its apical width; thyridium round, its distance from basal margin of tergite 2.0× its diameter. Third tergite 0.8× longer than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.8× longer than hind femur, ovipositor (Fig. 2D) gradually upcurved.
Colour. Black. Mandible except teeth, palpi, tegula, fore and mid trochanters and trochantellus, and hind trochantellus, yellow; scape and pedicel blackish brown; fore leg yellowish brown except coxa and telotarsus brown; mid leg yellowish brown except coxa and telotarsus brown, tibia apically infuscated; hind leg with coxa and trochanter black, femur, tibia subbasally and apically, tarsus from basal 0.7 on brown, remainder of hind leg whitish yellow; metasoma entirely black.
Distribution. China (Shaanxi).
Comparative diagnosis. This species is similar to C. taenius sp. nov., but differs from the latter by having interocellar distance 1.2× ocello-ocular distance, propodeal anterior transverse carina far removed from base, fore wing external angles of second discal cell less acute (75°), and third metasomal tergite 0.8× longer than its apical width.
Etymology. Name derived from “absitus” (Latin for “remote”), because its propodeal anterior transverse carina is far removed from base of propodeum.
