Body length 3.8 mm, fore wing length 2.8 mm.</p><p><b>Head.</b> Antenna with 23 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face (Fig. 78E) granulose. Clypeus (Fig. 78E) granulose, slightly convex, apical margin almost truncated. Malar space granulose, 0.45× basal width of mandible. Mandible with a weak lamella, upper tooth slightly longer than lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance (Fig. 78F) 1.6× 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.</p><p><b>Mesosoma.</b> Pronotum granulose dorsally, mat, trans-striate below. Mesoscutum (Fig. 78G) granulose, notauli indistinct. Scutellum and metanotum granulose. Mesopleuron (Fig. 78B) granulose, weakly trans-striate below tegula, speculum smooth and shiny. Metapleuron (Fig. 78B) granulose. Propodeum (Fig. 78C) with area basalis triangular; area superomedia granulose, mat; area petiolaris granulose; area superomedia confluent with area petiolaris, slightly depressed; all carina distinctly developed; propodeal spiracle small and oval.</p><p><b>Wing.</b> Fore wing (Fig. 78A) areolet present and with a short stalk, emitting 2m-cu vein from its apical part. Marginal cell short, distal part of surrounding vein 2.1× longer than proximal one. Vein 1cu-a opposite M&RS. External angles of second discal cell acute (60°). Hind wing with nervellus vertical, intercepted at lower 0.25.</p><p><b>Legs.</b> Hind femur 4.4× longer than wide. Inner spur of hind tibia 0.55× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.</p><p><b>Metasoma.</b> First metasomal segment (Fig. 78H) round in cross-section of basal 0.3, with dorso-lateral carina and a shallow lateral groove. First tergite 2.5× longer than width of postpetiole. Postpetiole and second tergite granulose, mat. Second tergite 0.75× as long as first tergite, 1.6× longer than its apical width; thyridium round, its distance from basal margin of tergite 1.8× its diameter. Third tergite 1.2× longer than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.7× longer than hind femur, ovipositor (Fig. 78D) gradually upcurved.</p><p><b>Colour.</b> Black. Mandible except teeth, palpi, tegula, fore and mid trochanters and trochantellus, and hind trochantellus, yellow; scape and pedicel blackish brown; fore and mid coxae basally and telotarsus brown, remainder of fore and mid legs yellowish brown; hind leg with coxa black, trochanter, femur, tibia subbasally and apically, tarsus from basal tarsomere 0.7 on blackish brown, remainder of hind leg whitish yellowish, and metasoma black with apical tergites laterally blackish brown.</p><p><b>Distribution.</b> China (Heilongjiang).</p><p><b>Comparative diagnosis.</b> This species is similar to C. <i>perpendicularis</i> <b>sp. nov.</b>, but differs from the latter by having upper tooth slightly longer than lower tooth, propodeal area superomedia wider, median area slightly depressed, costula weaker, medio-longitudinal carina not weak under costula, and metasoma black with apical tergites laterally blackish brown.</p><p><b>Etymology.</b> Name derived from “taenia” (Latin for “band”), because its hind tibia clearly banded.</p> |
