Type material. Holotype. CHINA • ♀; Fujian Province, Chong’an Dahe ; Oct. 1980; J.Y. Huang leg.; ZJUH 20004241 .
Diagnosis. This new species is very similar to C. promiscuus sp. nov., but can be separated from the latter by the following characters: metasomal tergites with yellowish white spots (metasomal tergites uniformly blackish brown in C. promiscuus ); vein 2-SC+R of hind wing relatively long, 0.8 × as long as vein 1r-m (short, 0.4 ×); hypoclypeal depression 1.6 × as wide as malar space (1.2 ×); frons with blackish brown spots (without dark spots); posterior margin of second metasomal tergite smooth (sculptured).
Description. Holotype, ♀, length of body 5.2 mm, of fore wing 5.9 mm, of ovipositor sheath 3.4 mm.
Head. Antenna with 42 antennomeres; apical flagellomere acute, 2.5 × longer than its maximum width ( Fig. 20k View FIGURE 20 ); first flagellomere 1.7 × longer than its maximum width, 1.1 and 1.2 × longer than second and third, respectively, the latter 1.3 × longer than wide; malar suture densely short setose, and with fine punctures ( Fig. 20i View FIGURE 20 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 1: 4: 2; clypeus sparsely long setose; eye weakly emarginated ( Fig. 20g View FIGURE 20 ); face 0.9 × longer than its width, densely long setose, and punctate ( Fig. 20g View FIGURE 20 ); eye height: shortest distance between eyes: head width = 12: 11: 22; frons largely smooth, concave behind antennal sockets, with a strong median groove ( Fig. 20h View FIGURE 20 ); vertex largely smooth except for some weak punctures, and with sparse short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 3: 4: 6; in dorsal view eye twice longer than temple; temples directly narrowed behind eyes ( Fig. 20h View FIGURE 20 ).
Mesosoma. Length of mesosoma 1.9 × its height ( Fig. 20c View FIGURE 20 ); notauli impressed anteriorly only ( Fig. 20d View FIGURE 20 ); mesoscutum largely with sparse long setae ( Fig. 20d View FIGURE 20 ); scutellar sulcus deep, moderately wide, and with crenulae ( Fig. 20d View FIGURE 20 ); scutellum with dense short setae posteriorly; metanotum strongly convex medially, and with a short median carina anteriorly ( Fig. 20d View FIGURE 20 ); propodeum smooth, without longitudinal carinae, sparsely setose medially, and densely long setose laterally ( Fig. 20d View FIGURE 20 ).
Wings. Fore wing ( Fig. 20a View FIGURE 20 ): SR1: 3-SR: r = 38: 21: 5; 1-SR+M distinctly bent after arising from 1-M; 2-SR: 3-SR: r-m = 9: 21: 4; angle between 1-SR and C+SC+R about 80°; r-m straight; cu-a interstitial. Hind wing ( Fig. 20b View FIGURE 20 ): SC+R1: 2-SC+R: 1r-m = 14: 5: 6.
Legs. Length of fore femur: tibia: tarsus = 16: 19: 26; length of hind femur: tibia: basitarsus = 25: 36: 38; length of femur, tibia and basitarsus of hind leg 4.1, 8.6 and 9.3 × their maximum width, respectively; hind tibial spurs 0.3 and 0.4 × as long as hind basitarsus.
Metasoma. Length of first metasomal tergite 1.4 × its apical width, median area convex and sculptured, with a medio-longitudinal carina posteriorly ( Fig. 20e View FIGURE 20 ); first tergite with developed lateral carinae, lateral grooves sparsely crenulate ( Fig. 20e View FIGURE 20 ); second tergite largely sculptured, but smooth posteriorly ( Fig. 20e View FIGURE 20 ); apical width of second tergite 1.9 × its median length, triangular medio-basal area of second tergite smooth, with some oblique carinae connected laterally, and attached with medio-longitudinal carina apically absent near posterior margin of second tergite; antero-lateral areas of second tergite weak and smooth, anterior grooves wide and crenulate ( Fig. 20e View FIGURE 20 ); second suture wide and deep, crenulate, straight medially ( Fig. 20e View FIGURE 20 ); third–fifth tergites with antero-lateral areas, and crenulate transverse subposterior groove ( Fig. 20e View FIGURE 20 ); third–seventh tergites largely smooth except a few weak punctures; ovipositor sheath 0.6 × as long as fore wing.
Colour. Head and mesosoma largely reddish yellow ( Fig. 19 View FIGURE 19 ); antenna, eyes, mandible apically ( Fig. 20g View FIGURE 20 ), frons medially and stemmaticum blackish brown ( Fig. 20h View FIGURE 20 ); metanotum and propodeum yellowish brown ( Fig. 20d View FIGURE 20 ); fore leg whitish yellow (except yellowish brown claws), middle and hind legs yellowish brown ( Fig. 20f View FIGURE 20 ); median area of first metasomal tergite blackish brown, remainder ivory ( Fig. 20e View FIGURE 20 ); second–fifth tergites largely blackish brown, but second tergite laterally, fourth tergite posterior-laterally and fifth tergite posteriorly ivory ( Fig. 20e View FIGURE 20 ); sixth and seventh tergites ivory ( Fig. 20e View FIGURE 20 ); wing membrane weakly infuscate, pterostigma and veins brown ( Figs 20a, 20b View FIGURE 20 ); ovipositor sheath black ( Fig. 19 View FIGURE 19 ).
Biology. Unknown.
Distribution. China (Fujian).
Etymology. Named after its rather square-shaped head in anterior view: “quadrus” and “ceps” are Latin for “square” and “head”, respectively.
