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 View FIGURE 22 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 17: 7; clypeus sparsely long setose; eye not emarginated ( Fig. 22g View FIGURE 22 ); width of hypoclypeal depression 1.2 × its height; length of face 0.9 × its width, coarsely sculptured and densely setose ( Fig. 22g View FIGURE 22 ); 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 View FIGURE 22 ); 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 View FIGURE 22 ).
Mesosoma. Length of mesosoma 1.7 × its height ( Fig. 22c View FIGURE 22 ); notauli only impressed anteriorly ( Fig. 22d View FIGURE 22 ); mesoscutum with short setae ( Fig. 22d View FIGURE 22 ); scutellar sulcus moderately wide and deep, with crenulae ( Fig. 22d View FIGURE 22 ); scutellum densely short stose posteriorly; metanotum strongly convex medially ( Fig. 22d View FIGURE 22 ); propodeum smooth without mediolongitudinal carina or groove, with dense long setae ( Fig. 22d View FIGURE 22 ).
Wings. Fore wing ( Fig. 22a View FIGURE 22 ): 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 View FIGURE 22 ): 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 View FIGURE 22 ); 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 View FIGURE 22 ); 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 View FIGURE 22 ); second suture wide and deep, crenulate, straight medially ( Fig. 22e View FIGURE 22 ); apical width of third tergite 3.5 × its median length; third tergite without subposterior groove ( Fig. 22e View FIGURE 22 ); third–fifth tergites coarsely sculptured, with antero-lateral areas (but of fifth tergite weak) ( Fig. 22e View FIGURE 22 ); fifth tergite with weak subposterior groove ( Fig. 22e View FIGURE 22 ); sixth and seventh tergites largely smooth except for a few weak striae and punctures ( Fig. 22e View FIGURE 22 ); ovipositor sheath 0.3 × as long as fore wing.
Colour. Largely black ( Fig. 21 View FIGURE 21 ); mandible (except for apically) and labial palp yellow ( Fig. 22g View FIGURE 22 ); outer margin of eyes, and antennal socket dorsally infuscate ( Fig. 22h View FIGURE 22 ); mesosoma reddish yellow ( Fig. 22e View FIGURE 22 ); fore tibia infuscate basally; wing membrane greyish brown, pterostigma and veins dark brown ( Figs 22a, 22b View FIGURE 22 ).
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.
