Figs 15–16 View FIGURE 15 View FIGURE 16
Type material. Holotype. CHINA • ♀; Hubei Province, Shennongjia Songbai ; 19 Jul. 1997; Y.Z. Du leg.; ZJUH 975309 . Paratype. CHINA • 1♀; Zhejiang Province, Tianmu Mt. ; 20 Jul. 1987; X.X. Chen leg.; ZJUH 872042 .
Diagnosis. This new species is very similar to C. brachyurus sp. nov., but can be separated from the latter by the following characters: third–fifth metasomal tergites uniformly blackish brown (third–fifth tergites with yellowish spots in C. brachyurus ); antennal scape relatively robust, 1.3 × as long as its maximum width (2.3 ×); mesopleuron, metanotum and metapleuron blackish brown (reddish yellow); transverse subposterior groove of fifth metasomal tergite complete (absent medially).
Description. Holotype, ♀, length of body 6.6 mm, of fore wing 6.2 mm, of ovipositor sheath 1.3 mm.
Head. Antenna incomplete, with 44 antennomere remaining; first flagellomere 1.3 × longer than its maximum width, 1.1 and 1.2 × longer than second and third flagellomeres, respectively, the latter 1.2 × longer than wide; malar suture sparsely short setose, and with fine punctures ( Fig. 16g View FIGURE 16 ); clypeus height: inter-tentorial distance: tentorioocular distance = 4: 9: 5; clypeus sparsely long setose; eye weakly emarginated ( Fig. 16g View FIGURE 16 ); face 0.7 × longer than wide, largely smooth, with some punctures and long setae ( Fig. 16g View FIGURE 16 ); eye height: shortest distance between eyes: head width = 19: 17: 37; frons smooth, concave behind antennal sockets, with a strong median groove ( Fig. 16h View FIGURE 16 ); vertex largely glabrous except for a few short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 1: 1: 2; in dorsal view length of eye 2.1 × temple; temples directly narrowed behind eyes ( Fig. 16h View FIGURE 16 ).
Mesosoma. Length of mesosoma 1.8 × its height ( Fig. 16c View FIGURE 16 ); notauli impressed anteriorly only ( Fig. 16d View FIGURE 16 ); mesoscutum largely glabrous, but with long setae along imaginary notaulic courses ( Fig. 16d View FIGURE 16 ); scutellar sulcus deep and wide, crenulate ( Fig. 16d View FIGURE 16 ); scutellum with dense short setae posteriorly; metanotum strongly convex medially, and with a short median carina anteriorly ( Fig. 16d View FIGURE 16 ); propodeum largely smooth, but with a few short longitudinal carinae latero- and medio-posteriorly, sparsely setose medially, and densely long setose laterally ( Fig. 16d View FIGURE 16 ).
Wings. Fore wing ( Fig. 16a View FIGURE 16 ): SR1: 3-SR: r = 34: 23: 7; 1-SR+M bent after arising from 1-M; 2-SR: 3-SR: r-m = 11: 23: 9; angle between 1-SR and C+SC+R about 80°; r-m straight; cu-a interstitial. Hind wing ( Fig. 16b View FIGURE 16 ): SC+R1: 2-SC+R: 1r-m = 18: 3: 10.
Legs. Length of fore femur: tibia: tarsus = 20: 24: 31; length of hind femur: tibia: basitarsus = 30: 40: 15; length of femur, tibia and basitarsus of hind leg 3.8, 6.9 and 5.0 × their maximum width, respectively; hind tibial spurs 0.3 and 0.4 × as long as hind basitarsus.
Metasoma. Length of first metasomal tergite 1.1 × its apical width, median area convex and coarsely sculptured, with a short medio-longitudinal carina posteriorly ( Fig. 16j View FIGURE 16 ); first tergite with developed lateral carinae, lateral grooves strongly crenulate ( Fig. 16j View FIGURE 16 ); second tergite largely coarsely sculptured, but smooth posteriorly ( Fig. 16e View FIGURE 16 ); apical width of second tergite 1.9 × its median length, triangular medio-basal area of second tergite smooth, connected to some transverse carinae laterally, and attached to medio-longitudinal carina apically absent near posterior margin of second tergite; antero-lateral areas of second tergite smooth, anterior grooves wide and crenulate ( Fig. 16e View FIGURE 16 ); second suture wide and deep, crenulate, straight medially ( Fig. 16e View FIGURE 16 ); third–fifth tergites with antero-lateral areas, and shallow crenulate transverse subposterior groove but flat medially (complete on fifth tergite) ( Fig. 16e View FIGURE 16 ); third–seventh tergites largely smooth except a few weak punctures; ovipositor sheath 0.2 × as long as fore wing.
Colour. Head and mesosoma largely reddish yellow ( Fig. 15 View FIGURE 15 ); antenna, eyes and apex of mandible blackish brown ( Fig. 16g View FIGURE 16 ); mesopleuron, metapleuron, metanotum and propodeum black ( Figs 16c, 16d View FIGURE 16 ); fore legs yellowish brown, middle and hind legs blackish brown ( Fig. 16f View FIGURE 16 ); metasomal tergites black, but sixth and seventh tergites ivory ( Figs 16e, 16j View FIGURE 16 ); wing membrane infuscate, pterostigma and veins yellowish brown ( Figs 16a, 16b View FIGURE 16 ); ovipositor sheath black ( Fig. 15 View FIGURE 15 ).
Variation. Length of body of female 6.4–6.6 mm, and of ovipositor sheath 1.1–1.3 mm; antenna of one female with 53 antennomeres, its apical flagellomere acute and 2.5 × longer than wide.
Biology. Unknown.
Distribution. China (Hubei, Zhejiang).
Etymology. Named after the relatively robust scapus: “pachys” is Greek for “thick”.
