Figs. 67–68

Material examined. Holotype: female, Xinjiang, Hetian Moyu, 30.VIII.2004, Tu Erxun, No 200601107 ( ZJUH).

Description. Female ( Fig. 67 ) holotype. Body length 4.8 mm, fore wing length 3.5 mm.

Head. Antenna with 23 flagellomeres; first flagellomere 1.3× longer than second flagellomere. Face ( Fig. 68E ) granulose. Clypeus ( Fig. 68E ) mat, not convex, apical margin truncated, sharp. Malar space granulose, 0.5× basal width of mandible. Mandible with a very weak lamella, with upper tooth longer than lower tooth. Frons granulose, median carina absent. Vertex granulose. Interocellar distance ( Fig. 68F ) 1.3× ocello-ocular distance and 1.8× distance between median and lateral ocelli. Temple swollen behind eye, mat. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose dorsally with minute punctures, trans-striate below. Mesoscutum ( Fig. 68G ), scutellum and metanotum granulose. Mesopleuron ( Fig. 68B ) granulose, weakly trans-striate below tegula, speculum smooth and shiny. Propodeum ( Fig. 68C ) granulose; area basalis triangular; area superomedia granulose; area petiolaris trans-striate; area superomedia confluent with area petiolaris, not depressed medially; all carina strong; propodeal spiracle small and oval.

Wing. Fore wing ( Fig. 68A ) 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 (70°). Hind wing with nervellus vertical, intercepted at lower 0.2 of its length.

Legs. Hind femur 3.8× longer than wide. Inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus. Tarsal claws pectinate, its teeth weak.

Metasoma. First metasomal segment ( Fig. 68H ) round in cross-section of basal 0.3, without dorso-lateral carina and lateral groove. Postpetiole and second tergite granulose. Second tergite 0.6× as long as first tergite, as long as its apical width; thyridium oval, its distance from basal margin of tergite equal to its length. Third tergite 0.62× longer than its apical width. Sixth and seventh tergites without emarginations medially. Ovipositor sheath approx. 1.2× longer than hind femur, ovipositor ( Fig. 68D ) gradually upcurved.

Colour. Black. Mandible except teeth, palpi and tegula whitish yellow; scape and pedicel brown; fore coxa basally brown, trochanter and trochantellus yellow, remainder of fore leg yellowish brown; mid coxa basally and telotarsus brown, trochanter and trochantellus yellow, remainder of mid leg yellowish brown; hind coxa blackish, trochanter basally brown, trochantellus yellow, femur and trochanter apically yellowish brown, tibia subbasally and apically infuscated, medially whitish yellow, tarsus from basal tarsomere 0.8 on blackish brown, basal tarsomere 0.8 whitish yellow; metasoma with first tergite black, second tergite blackish brown, from third tergite on each tergite apically yellowish brown, basally brown.

Distribution. China (Xinjiang).

Comparative diagnosis. This species is similar to C. cyclus sp. nov., but differs from the latter by having first flagellomere 1.3× longer than second flagellomere, inner spur of hind tibia 0.6× as long as first tarsomere of hind tarsus, mid and hind femur yellowish brown, and metasoma not entirely black.

Etymology. Name derived from “pseudo” (Greek for “pseudo”), and the specific name “cyclus”, because of its similarity to C. cyclus sp. nov.
