Type material. Holotype. CHINA • ♀; Guangdong Province, Guangzhou; 1 Nov. 1989; J.H. He leg.; ZJUH 896611. Paratype. CHINA • 1♀; Fujian Province, Chong’an Tongmu; 790–1155m; 10 Apr. 1960; G. T. Jin & Y.M. Lin leg.; SHEM 34023744.
Diagnosis. This new species is very similar to C. gibbiventris Enderlein, 1920, but can be separated from the latter by the following characters: head and mesosoma mainly black, with ivory spots (head and mesosoma entirely black in C. gibbiventris); fifth tergite coarsely sculptured (smooth); ovipositor shorter, 0.2 × as long as body (0.4 ×); metasomal tergites mainly black, with whitish yellow spots (entirely black); wing membrane smoky grey, pterostigma and veins dark brown (wing membrane, pterostigma and veins blackish brown).
Description. Holotype, ♀, length of body 4.5 mm, of fore wing 4.8 mm, of ovipositor sheath 0.8 mm.
Head. Antenna with 40 antennomeres; apical flagellomere acute and weakly protruding apically, 2.4 × longer than its maximum width (Fig. 26l); first flagellomere 1.4 × longer than its maximum width, 1.2 and 1.3 × longer than second and third, respectively, the latter 1.3 × longer than wide; malar suture weakly sculptured and sparsely short setose (Fig. 26i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 3: 13: 6; clypeus sparsely short setose; eye weakly emarginated (Fig. 26g); width of hypoclypeal depression 1.5 × its height; face 0.8 × longer than wide, coarsely punctate and with a few weak striae near eyes, sparsely setose laterally (Fig. 26g); eye height: shortest distance between eyes: head width = 15: 13: 30; frons smooth, weakly concave behind antennal sockets, with a strong median groove (Fig. 26h); vertex smooth, with sparse short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 7: 7: 10; in dorsal view length of eye twice temple; temples linearly narrowed behind eyes (Fig. 26h).
Mesosoma. Length of mesosoma 1.4 × its height (Fig. 26c); notauli only impressed anteriorly (Fig. 26d); mesoscutum with dense short setae (Fig. 26d); scutellar sulcus narrow and deep, with sparse crenulae (Fig. 26d); scutellum sparsely short setose; metanotum strongly convex medially (Fig. 26d); propodeum smooth, without medio-longitudinal carina or groove, sparsely setose medially, and densely long setose laterally (Fig. 26d).
Wings. Fore wing (Fig. 26a): pterostigma 3.7 × longer than wide; SR1: 3-SR: r = 31: 22: 5; 1-SR+M rather weakly curved subbasally; 2-SR: 3-SR: r-m = 11: 22: 10; angle between 1-SR and C+SC+R about 75°; cu-a interstitial, vertical. Hind wing (Fig. 26b): SC+R1: 2-SC+R: 1r-m = 6: 2: 3.
Legs. Length of fore femur: tibia: tarsus = 19: 22: 30; length of hind femur: tibia: basitarsus = 26: 37: 15; length of femur, tibia and basitarsus of hind leg 3.3, 6.7 and 4.9 × their maximum width, respectively; hind tibial spurs 0.4 and 0.5 × as long as hind basitarsus.
Metasoma. Length of first metasomal tergite 0.9 × its apical width, median area convex and coarsely sculptured, without medio-longitudinal carina posteriorly, lateral grooves sparsely crenulate (Fig. 26j); second tergite largely coarsely sculptured, triangular medio-basal area smooth (but with some crenulae at outer margin), attached to medio-longitudinal carina apically, the latter not reaching posterior margin of second tergite (Fig. 26e); apical width of second tergite 2.4 × its median length, antero-lateral areas of second tergite rather small and smooth, anterior grooves wide and with weak sparse crenulae apically (Fig. 26e); second suture wide and deep, crenulate, nearly straight medially (Fig. 26e); apical width of third tergite 3.6 × its median length; third–fifth tergites coarsely sculptured, with antero-lateral areas (fifth tergite weak) and subposterior groove (Fig. 26e); sixth and seventh tergites largely smooth; ovipositor sheath 0.2 × as long as fore wing.
Colour. Largely black (Fig. 25); frons laterally (up to eyes), face laterally, area surrounding malar suture, posterior half of middle lobe of mesoscutum, mesopleuron anteriorly and scutellum white or ivory (Figs 26c, 26d, 26g, 26h); first metasomal tergite (except for median area), second tergite laterally (except posteriorly), third tergite antero-laterally and posteriorly, fourth–seventh tergites posteriorly whitish yellow (Fig. 26e); wing membrane smoky grey, pterostigma and veins dark brown (Figs 26a, 26b).
Variation. Length of body of female 4.5–6.0 mm, of fore wing of female 4.8–6.2 mm, and of ovipositor sheath 0.8–1.0 mm; length of mesosoma 1.5 × its height; spots of head pale yellow in paratype; pronotum laterally and lateral lobes of mesoscutum anteriorly whitish yellow or black.
Biology. Unknown.
Distribution. China (Fujian, Guangdong).
Etymology. Named after the multiple spots of the head: “stigmosus” is Latin for “full of marks”.
