Type material. Holotype. CHINA • ♀; Hunan Province, Liuyang; 24 Aug. 1985; X.W. Tong leg.; ZJUH 864625.
Diagnosis. This new species is very similar to C. serenans Enderlein, 1920, but can be separated from the latter by the following characters: ovipositor sheath 0.3 × as long as fore wing (0.7 × as long as fore wing in C. serenans); mesosoma entirely reddish yellow (reddish brown except for mesoscutum and metapleuron black); first metasomal tergite entirely black (black except whitish yellow laterally).
Description. Holotype, ♀, length of body 7.3 mm, of fore wing 6.3 mm, of ovipositor sheath 2.1 mm.
Head. Antenna incomplete, with 51 antennomeres remaining; first flagellomere 1.4 × longer than its maximum width, 1.2 and 1.3 × longer than second and third, respectively, the latter 1.2 × longer than wide; malar suture densely short stose (Fig. 22i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 17: 7; clypeus sparsely long setose; eye not emarginated (Fig. 22g); width of hypoclypeal depression 1.2 × its height; length of face 0.9 × its width, coarsely sculptured and densely setose (Fig. 22g); eye height: shortest distance between eyes: head width = 24: 22: 45; frons smooth, weakly concave behind antennal sockets, with a strong median groove (Fig. 22h); vertex smooth, with dense short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 4: 5: 7; in dorsal view length of eye 1.8 × temple; temples strongly narrowed behind eyes (Fig. 22h).
Mesosoma. Length of mesosoma 1.7 × its height (Fig. 22c); notauli only impressed anteriorly (Fig. 22d); mesoscutum with short setae (Fig. 22d); scutellar sulcus moderately wide and deep, with crenulae (Fig. 22d); scutellum densely short stose posteriorly; metanotum strongly convex medially (Fig. 22d); propodeum smooth without mediolongitudinal carina or groove, with dense long setae (Fig. 22d).
Wings. Fore wing (Fig. 22a): pterostigma 3.5 × longer than wide; SR1: 3-SR: r = 36: 25: 9; 1-SR+M strongly bent subbasally; 2-SR: 3-SR: r-m = 10: 25: 10; angle between 1-SR and C+SC+R about 80°; cu-a narrowly postfurcal, vertical. Hind wing (Fig. 22b): SC+R1: 2-SC+R: 1r-m = 17: 7: 14.
Legs. Length of fore femur: tibia: tarsus = 20: 25: 34; length of hind femur: tibia: basitarsus = 32: 46: 17; length of femur, tibia and basitarsus of hind leg 3.6, 9.2 and 5.7 × their maximum width, respectively; hind tibial spurs 0.3 and 0.4 × as long as hind basitarsus.
Metasoma. Metasomal tergites densely setose; length of first metasomal tergite 1.3 × its apical width, median area convex and coarsely sculptured, with a rather short medio-longitudinal carina posteriorly, lateral grooves crenulate (Fig. 22j); second tergite largely coarsely sculptured, triangular medio-basal area of second tergite rather weakly sculptured, attached to medio-longitudinal carina apically, the latter reaching posterior margin of second tergite (Fig. 22e); apical width of second tergite twice its median length, antero-lateral areas of second tergite rather small and smooth, anterior grooves wide and crenulate (Fig. 22e); second suture wide and deep, crenulate, straight medially (Fig. 22e); apical width of third tergite 3.5 × its median length; third tergite without subposterior groove (Fig. 22e); third–fifth tergites coarsely sculptured, with antero-lateral areas (but of fifth tergite weak) (Fig. 22e); fifth tergite with weak subposterior groove (Fig. 22e); sixth and seventh tergites largely smooth except for a few weak striae and punctures (Fig. 22e); ovipositor sheath 0.3 × as long as fore wing.
Colour. Largely black (Fig. 21); mandible (except for apically) and labial palp yellow (Fig. 22g); outer margin of eyes, and antennal socket dorsally infuscate (Fig. 22h); mesosoma reddish yellow (Fig. 22e); fore tibia infuscate basally; wing membrane greyish brown, pterostigma and veins dark brown (Figs 22a, 22b).
Biology. Unknown.
Distribution. China (Hunan).
Etymology. Named after the robust second submarginal cell of the fore wing: “robustus” and “cella” are Latin for “hard and strong” and “chamber”, respectively.
