Type material. Holotype. CHINA • ♀; Yunnan Province, Xishuangbanna, Meng’a; 1050–1080m; 8 Aug. 1958; F.J. Pu leg.; IZCAS IOZ (E)1964565. Paratypes. CHINA • 1♀; ibid.; but from Xiaomengyang; 850m; 12 Sep. 1957; S.Y. Wang leg.; IZCAS IOZ (E) 1964569 • 1♀; ibid.; but from Mengla; 620–650m; 13 Jul. 1959, F.J. Pu leg.; IZCAS IOZ (E) 1964619.
Diagnosis. This new species is very similar to C. brunneomaculatus (Cameron, 1903), but can be separated from the latter by the following characters: ovipositor sheath relatively long, 0.4–0.6 × as long as body (0.2 × as long as body in C. brunneomaculatus); second metasomal tergite with medio-basal triangular area coarsely sculptured (smooth); head uniformly black (head brown and vertex largely black); second–fourth metasomal tergites with similar distinct longitudinal striae (third and fourth metasomal tergites with relatively weak sculpture compare to second metasomal tergite); antennal flagellomeres black (light brown).
Description. Holotype, ♀, length of body 8.0 mm, of fore wing 7.2 mm, of ovipositor sheath 3.1 mm.
Head. Antenna with 50 antennomeres; apical flagellomere acute and protruding apically, 2.1 × longer than its maximum width (Fig. 6l); first flagellomere 1.7 × longer than its maximum width, 1.2 and 1.3 × longer than second and third flagellomeres, respectively, the latter being 1.2 × longer wide; malar suture moderately developed, sculptured (Fig. 6i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 9: 5; clypeus densely long setose; eye not emarginated (Fig. 6g); face 0.9 × longer than wide, densely long setose, and coarsely sculptured (Fig. 6g); eye height: shortest distance between eyes: head width = 19: 17: 38; frons smooth except for some weak punctures, concave behind antennal sockets, with a strong median groove (Fig. 6h); vertex smooth, with sparse short setae; shortest distance between posterior ocelli: narrower diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 3: 4: 9; in dorsal view length of eye 1.8 × temple; temples linearly narrowed behind eyes (Fig. 6h).
Mesosoma. Length of mesosoma 1.7 × its height (Fig. 6c); notauli only impressed anteriorly (Fig. 6d); mesoscutum with a few punctures (Fig. 6d); scutellar sulcus deep and wide, with crenulae (Fig. 6d); scutellum densely punctate and short setose; metanotum strongly convex medially; propodeum sparsely punctate, with a short mediolongitudinal carina posteriorly, sparsely setose medially, and densely long setose laterally (Fig. 6d).
Wings. Fore wing (Fig. 6a): SR1: 3-SR: r = 25: 20: 3; 1-SR+M rather weakly curved after arising from 1-M; 2-SR: 3-SR: r-m = 9: 26: 9; angle between 1-SR and C+SC+R about 80°; r-m rather weakly curved; cu-a interstitial. Hind wing (Fig. 6b): SC+R1: 2-SC+R: 1r-m = 19: 5: 10.
Legs. Length of fore femur: tibia: tarsus = 21: 24: 27; length of hind femur: tibia: basitarsus = 30: 46: 16; length of femur, tibia and basitarsus of hind leg 2.7, 6.1 and 4.0 × their maximum width, respectively; hind tibial spurs 0.4 and 0.6 × as long as hind basitarsus.
Metasoma. Metasomal tergites strongly sculptured (Fig. 6e); first tergite as long as its apical width, median area convex and with a medio-longitudinal carina (Fig. 6j); first tergite with developed lateral carinae, lateral grooves crenulate (Fig. 6j); apical width of second tergite 2.3 × its median length, triangular medio-basal area of second tergite rugose, without medio-longitudinal carina; antero-lateral areas of second tergite absent, anterior grooves deep and crenulate (Fig. 6e); second suture wide and deep, crenulate, distinctly curved medially (Fig. 6e); third–fifth tergites with weakly antero-lateral areas, and transverse subposterior groove absent (Fig. 6e); ovipositor sheath 0.6 × as long as fore wing.
Colour. Black (Fig. 5); basal half of wing membrane blackish grey and apical half whitish; apical quarter of pterostigma yellow and remainder black; veins blackish brown or yellow (Figs 6a, 6b).
Variation. Length of body 8.3–9.0 mm, of fore wing 8.2–8.3 mm (♀), and of ovipositor sheath 5.0– 5.2 mm; antenna of ♀ with 52–56 antennomeres; length of mesosoma 1.5–1.6 × its height; propodeum sometimes blackish brown.
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after its densely setose face: “lasios” (Greek for “hairy”) and “facies” is Latin for “face”.
