Type material. Holotype. CHINA • ♀; Yunnan Province, Ruili; 6 May 1981; J.H. He leg.; ZJUH 813011.
Diagnosis. This new species is very similar to C. latesuturalis Turner, 1919, but can be separated from the latter by the following characters: notauli often impressed anteriorly and reduced posteriorly (notauli nearly reaching posterior margin of mesoscutum in C. latesuturalis); fourth and fifth metasomal tergites longitudinally striate (coarsely punctate); mesoscutum yellow, but lateral lobes and medio-anterior part of median lobe with a black spot (reddish brown and without black spots); pterostigma and most veins yellow (black); ovipositor sheath shorter, 0.5 × as long as body (longer, 0.75 × as long as body).
Description. Holotype, ♀, length of body 8.4 mm, of fore wing 8.8 mm, of ovipositor sheath 4.1 mm.
Head. Antenna with 48 antennomeres; apical flagellomere acute, 2.3 × longer than its maximum width (Fig. 10k); first flagellomere 1.7 × longer than its maximum width, 1.4 and 1.5 × longer than second and third flagellomeres, respectively, the latter 1.1 × longer than wide; malar suture moderately developed, coarsely rugose and densely short setose (Fig. 10i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 11: 9; clypeus long setose; eye weakly emarginated (Fig. 10g); face 0.7 × longer than wide, densely long setose, and coarsely sculptured (Fig. 10g); eye height: shortest distance between eyes: head width = 19: 17: 38; frons largely glabrous except for some sparse setae, concave behind antennal sockets, with a strong median groove (Fig. 10h); vertex largely glabrous, but with some sparse short setae; shortest distance between posterior ocelli: narrower diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 10: 9: 20; in dorsal view length of eye 1.8 × temple; temples linearly narrowed behind eyes (Fig. 10h).
Mesosoma. Length of mesosoma 1.6 × its height (Fig. 10c); notauli only impressed anteriorly (Fig. 10d); mesoscutum largely glabrous, except for some long setae along notauli (Fig. 10d); scutellar sulcus deep and narrow, with crenulae (Fig. 10d); scutellum densely punctate and short setose; metanotum strongly convex medially, and with a short median carina anteriorly (Fig. 10d); propodeum largely smooth, except for a few short lateral carinae posteriorly, sparsely setose medially, and densely long setose laterally (Fig. 10d).
Wings. Fore wing (Fig. 10a): SR1: 3-SR: r = 40: 32: 5; 1-SR+M strongly bent after arising from 1-M; 2-SR: 3SR: r-m = 8: 32: 9; angle between 1-SR and C+SC+R about 75°; r-m weakly curved; cu-a weakly postfurcal. Hind wing (Fig. 10b): SC+R1: 2-SC+R: 1r-m = 15: 3: 10.
Legs. Length of fore femur: tibia: tarsus = 22: 25: 37; length of hind femur: tibia: basitarsus = 27: 43: 17; length of femur, tibia and basitarsus of hind leg 3.5, 7.1 and 5.8 × their maximum width, respectively; hind tibial spurs 0.40 and 0.35 × as long as hind basitarsus.
Metasoma. Metasomal tergites largely longitudinally sculptured (Fig. 10e); length of first tergite 1.1 × its apical width, median area convex and with a short medio-longitudinal carina posteriorly (Fig. 10e); first tergite with distinct lateral carinae, lateral grooves crenulate (Fig. 10e); apical width of second tergite 1.9 × its median length, triangular medio-basal area of second tergite glabrous, attached to medio-longitudinal carina absent near posterior margin of second tergite; antero-lateral areas of second tergite absent, anterior grooves deep and crenulate (Fig. 10e); second suture wide, crenulate, straight medially (Fig. 10e); third–fifth tergites with weak antero-lateral areas, and transverse subposterior groove crenulate (Fig. 10e); sixth and seventh tergites glabrous, with some weak punctures posteriorly; ovipositor sheath 0.5 × as long as fore wing.
Colour. Largely black (Fig. 9); but head mostly yellow, antenna, eyes and apex of mandible black brown; pronotum, scutellum and metanotum yellow; lateral and middle lobes of mesoscutum with a black spot anteriorly; fore and middle claws dark brown; hind leg black brown (Fig. 10f); sixth and seventh metasomal tergites yellow posteriorly (Fig. 10e); wing membrane largely infuscate, brownish grey apically, stigmal spot dark brown, pterostigma and veins infuscate (Figs 10a, 10b).
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the largely longitudinally sculptured metasomal tergites: “longitudo” is Latin for “length”.
