Figs. 3–4

Materia examined. Holotype: female, Liaoning, Shenyang , 10.VII.1994, Lou Juxian, No947297 . Paratypes: 2 males, Liaoning, Shenyang, VI–VII. 1995, Lou Juxian, No 960909, No 960913 .

Description. Female holotype. Body length 9.7 mm, fore wing length 5.3 mm.

Head. Antenna with 38 flagellomeres; first flagellomere 1.5× longer than second flagellomere. Face strongly rugose. Clypeus rugose-punctate, slightly convex, apical margin curved. Malar space granulose, 0.6× basal width of mandible. Mandible with lamella. Frons rugose, with a median carina. Vertex granulose. Interocellar distance twice ocello-ocular distance and 1.6× distance between median and lateral ocelli. Temple granulose, mat. Occipital carina evenly arched.

Mesosoma. Pronotum rugose-punctate above, trans-striate below. Mesoscutum rugose-punctate, rugosities weak medially. Scutellum rugose-punctate. Metanotum rugose-punctate. Mesopleuron granulose-punctate, transversely striate below tegula, striations long and covered region of speculum. Metapleuron strongly rugose, juxtacoxal carina strong, juxta-coxal area finely rugose. Propodeum with anterior transverse carina very close to base, and area basalis nearly absent; area superomedia confluent with area petiolaris, rugose with area petiolaris apically tending to be transversely striate; area dentipara rugose-punctate; area lateralis finely trans-rugose; all carinae strong; propodeal spiracle oval.

Wing. Fore wing without areolet. Marginal cell short, RS vein 1.6× longer than 2r&RS vein. Vein 1cu-a slightly distad of M&RS. External angles of second discal cell slightly acute(80°). Hind wing with 1-cu reclivous, ca 3.0× longer than cu-a.

Legs. Hind femur 5.2× longer than wide. Inner spur of hind tibia 0.7× as long as first tarsomere of hind tarsus. Tarsal claws pectinate.

Metasoma. Slender. Basal 0.3 of first metasomal segment round in cross-section. Second tergite 0.7× as long as first tergite; thyridium elongate oval, its distance from basal margin of tergite ca 3.5× its length; metasoma from third to seventh tergites strongly compressed. Ovipositor 1.1× longer than hind femur, straight.

Colour. Black. Scape and pedicel, mandible, tegulae black; palpi brown. Fore leg with coxa, trochanter, trochantellus, inner side of basal 0.3 of femur and apical tarsus, blackish brown, remainder of fore leg yellowish brown. Mid leg with coxa, trochanter, trochantellus, basal 0.7 of femur and tarsus, blackish brown, remainder of mid leg yellowish brown. Hind leg entirely black. First metasomal segment with sternum blackish brown, tergite yellowish brown; dorsal surface of second segment black and its lateral surface yellowish brown; third tergite yellowish brown with a black mark antero-dorsally; fourth segment yellowish brown; remainder of metasoma blackish brown.

Male. Malar space sculpture coarser, tending to be rugose-punctate, about equal to the length of basal width of mandible. Thyridium larger, its distance from basal margin of tergite ca 3.0× its length. Otherwise same as the female.

Male genitalia. Parameres broad, not rod-like.

Distribution. China (Liaoning).

Comparative diagnosis. This species runs in the key by Maheshwary & Gupta (1971) to C. ganges Cushman, 1927 , but the new species differs from latter by having interocellar distance twice ocello-ocular distance (4.0–4.7× in C. ganges ), malar space granulose and 0.6× basal width of mandible (malar space rugose and 0.37–0.46× basal width of mandible in C. ganges ), mesopleuron granulose-punctate (rugoso-reticulate in C. ganges ), juxta-coxal area finely rugose (with a few striations in C. ganges ), mandible black (mandible yellow except teeth in C. ganges ), palpi brown (black in C. ganges ) and hind leg entirely black (hind leg not entirely black in C. ganges ).

Etymology. Name derived from mauros (Greek for black) and kneme (Greek for leg), because of the entirely black hind leg.
