Type material. Holotype. CHINA • ♀; Yunnan Province, Xishuangbanna Mengla; 620–650m; light trap; 12 Jul. 1959; F.J. Pu leg.; IZCAS IOZ (E)1964627. Paratypes. CHINA • 1♀; sama data as holotype; IZCAS IOZ (E) 1964631 • 1♀; Yunnan Province, Simao; 1500m; 24 Apr. 1982; G. T. Jin leg.; SHEM 34005151.
Diagnosis. This new species is very similar to C. kirbyi (Cameron, 1905), but can be separated from the latter by the following characters: flagellomeres of antenna blackish brown, scapus and pedicel with a black brown stripe on outer side, respectively (antenna entirely black in C. kirbyi); ovipositor sheath 0.3–0.4 × as long as fore wing (0.6–0.8 ×); first metasomal tergite without medio-longitudinal carina posteriorly (with medio-longitudinal carina posteriorly); face coarsely punctate (irregularly rugose); median groove of frons less deep (very deep and clearly defined).
Description. Holotype, ♀, length of body 8.7 mm, of fore wing 9.3 mm, of ovipositor sheath 3.8 mm.
Head. Antenna incomplete, with 75 antennomeres remaining; first flagellomere 1.1 × longer than its maximum width, 1.1 and 1.2 × longer than second and third, respectively, the latter 0.9 × longer than wide; malar suture sparsely long stose (Fig. 28i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 5: 9: 6; clypeus sparsely short setose; eye weakly emarginated (Fig. 28g); width of hypoclypeal depression 1.3 × its height; face 0.9 × longer than wide, coarsely densely punctate and densely long setose (Fig. 28g); eye height: shortest distance between eyes: head width = 22: 17: 40; frons smooth, weakly concave behind antennal sockets, with a median groove (Fig. 28h); vertex smooth, with sparse short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 5: 4: 8; in dorsal view length of eye 2.2 × temple; temples linearly narrowed behind eyes (Fig. 28h).
Mesosoma. Length of mesosoma 1.7 × its height (Fig. 28c); notauli only impressed anteriorly (Fig. 28d); mesoscutum with sparse short setae (Fig. 28d); scutellar sulcus narrow and deep, with crenulae (Fig. 28d); scutellum short setose posteriorly; metanotum strongly convex medially (Fig. 28d); propodeum largely smooth except for a few rather weak longitudinal striae medially and sparse punctures laterally, without medio-longitudinal carina or groove, glabrous medially, and densely long setose laterally (Fig. 28d).
Wings. Fore wing (Fig. 28a): pterostigma 3.9 × longer than wide; SR1: 3-SR: r = 26: 21: 5; 1-SR+M rather strongly curved subbasally; 2-SR: 3-SR: r-m = 9: 21: 8; angle between 1-SR and C+SC+R about 85°; cu-a weakly postfurcal, slightly oblique anteriorly. Hind wing (Fig. 28b): SC+R1: 2-SC+R: 1r-m = 25: 4: 15.
Legs. Length of fore femur: tibia: tarsus = 26: 31: 37; length of hind femur: tibia: basitarsus = 38: 59: 22; length of femur, tibia and basitarsus of hind leg 3.8, 9.8 and 5.5 × 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 crenulate (Fig. 28j); second tergite largely coarsely sculptured, triangular medio-basal area of second tergite weakly rugose, attached with medio-longitudinal carina apically, the latter not reaching posterior margin of second tergite (Fig. 28e); apical width of second tergite 1.7 × its median length, antero-lateral areas of second tergite rather small and smooth, anterior grooves wide and with weak sparse crenulae (Fig. 28e); second suture wide and deep, crenulate, weakly curved medially (Fig. 28e); apical width of third tergite 3.6 × its median length; third and fourth tergites coarsely sculptured (fourth tergite densely punctate laterally), with distinct antero-lateral areas, oblique anterior grooves and subposterior groove with crenulae (Fig. 28e); fifth tergite sparsely punctate (Fig. 28e); sixth and seventh tergites largely smooth; ovipositor sheath 0.4 × as long as fore wing.
Colour. Largely yellow (Fig. 27); flagellomeres of antenna and mandible apically blackish brown (Fig. 28g); scapus and pedicel with a black brown stripe on outer side, respectively (Fig. 28i); wing membrane yellowish, but infuscate apically, stigmal spot dark brown, up to base of vein 1-SR+M, pterostigma yellow, but apical third dark brown, basal veins yellow (vein 1-SR+M dark brown subbasally), and apical veins brownish yellow (Figs 28a, 28b).
Variation. Length of body of female 8.7–9.5 mm, of fore wing of female 9.3–11.0 mm, and of ovipositor sheath 3.7–4.0 mm; vein SR1 of fore wing 1.3–1.4 × vein 3-SR; vein SC+R1 of hind wing 1.2–1.5 × vein 1r-m; ovipositor sheath 0.3–0.4 × as long as fore wing; sometimes scapus brownish yellow ventrally or entirely blackish brown.
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the punctate fourth and fifth tergites: “tergum” and “punctum” are Latin for “back” and “small hole, dot”, respectively.
