Figs 17–18 View FIGURE 17 View FIGURE 18

Type material Holotype. CHINA • ♀; Guangdong Province, Hua County; Jun. 1976; Y.Q. Liu leg.; host: Semanotus bifasciatus (Motschulsky) ; ZJUH 760716 . Paratypes. CHINA • 2³³; same data as holotype; ZJUH 760716 (two specimens) .

Diagnosis. This new species is very similar to C. gibbiventris Enderlein, 1920 , but can be separated from the latter by the following characters: head and mesosoma mainly reddish yellow (head and mesosoma entirely black in C. gibbiventris ); third and fourth metasomal tergites largely coarsely punctate (densely and weakly curved longitudinally striate); fifth tergite coarsely punctate (smooth); wing membrane yellow or subhyaline, pterostigma and veins yellowish brown (wing membrane, pterostigma and veins blackish brown).

Description. Holotype, ♀, length of body 6.3 mm, of fore wing 6.7 mm, of ovipositor sheath 3.7 mm.

Head. Antenna with 42 antennomeres; apical flagellomere acute, 1.7 × longer than its maximum width ( Fig. 18k View FIGURE 18 ); first flagellomere 1.4 × longer than its maximum width, 1.1 and 1.2 × longer than second and third, respectively, the latter being 1.3 × longer than wide; malar suture densely short stose, and with fine sculpture ( Fig. 18i View FIGURE 18 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 1: 3: 2; clypeus sparsely long setose; eye nearly immarginated ( Fig. 18g View FIGURE 18 ); face 0.8 × longer than wide, densely long setose and coarsely sculptured ( Fig. 18g View FIGURE 18 ); eye height: shortest distance between eyes: head width = 1: 1: 2; frons largely smooth, concave behind antennal sockets, with a strong median groove ( Fig. 18h View FIGURE 18 ); vertex smooth, with sparse short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 4: 3: 6; in dorsal view length of eye 1.3 × temple; temples weakly narrowed behind eyes ( Fig. 18h View FIGURE 18 ).

Mesosoma. Length of mesosoma 1.5 × its height ( Fig. 18c View FIGURE 18 ); notauli only impressed anteriorly ( Fig. 18d View FIGURE 18 ); mesoscutum sparsely punctate, along notauli with long setae ( Fig. 18d View FIGURE 18 ); scutellar sulcus deep, moderately wide, and with crenulae ( Fig. 18d View FIGURE 18 ); scutellum sparsely punctate, with dense short setae posteriorly; metanotum strongly convex medially, and with a short median carina anteriorly ( Fig. 18d View FIGURE 18 ); propodeum largely smooth, but with a few short longitudinal carinae latero- and medio-posteriorly, sparsely setose medially, and densely long setose laterally ( Fig. 18d View FIGURE 18 ).

Wings. Fore wing ( Fig. 18a View FIGURE 18 ): SR1: 3-SR: r = 30: 17: 4; 1-SR+M strongly bent after arising from 1-M; 2-SR: 3-SR: r-m = 8: 17: 8; angle between 1-SR and C+SC+R about 85°; r-m nearly straight; cu-a interstitial. Hind wing ( Fig. 18b View FIGURE 18 ): SC+R1: 2-SC+R: 1r-m = 11: 3: 7.

Legs. Length of fore femur: tibia: tarsus = 16: 20: 23; length of hind femur: tibia: basitarsus = 23: 34: 11; length of femur, tibia and basitarsus of hind leg 3.3, 7.8 and 5.5 × their maximum width, respectively; hind tibial spurs 0.4 and 0.5 × as long as hind basitarsus.

Metasoma. First tergite as long as its apical width, median area convex and coarsely sculptured, with a mediolongitudinal carina posteriorly ( Fig. 18e View FIGURE 18 ); first tergite with developed lateral carinae, lateral grooves crenulate ( Fig. 18e View FIGURE 18 ); second tergite largely sculptured ( Fig. 18e View FIGURE 18 ); apical width of second tergite 2.1 × its median length, triangular medio-basal area of second tergite smooth, bordered a few transverse carinae antero-laterally, and attached to 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. 18e View FIGURE 18 ); second suture wide and deep, crenulate, straight medially ( Fig. 18e View FIGURE 18 ); third–fifth tergites with some strong punctures, with weak antero-lateral areas, and crenulate transverse subposterior groove ( Fig. 18e View FIGURE 18 ); sixth and seventh tergites largely smooth; ovipositor sheath 0.6 × as long as fore wing.

Colour. Head and mesosoma largely reddish yellow ( Fig. 17 View FIGURE 17 ); antenna, eyes, mandible apically ( Fig. 18g View FIGURE 18 ), and propodeum laterally and medio-basally blackish brown ( Fig. 18d View FIGURE 18 ); legs and metasoma blackish brown ( Figs 18e, 18f View FIGURE 18 ); ovipositor sheath black ( Fig. 17 View FIGURE 17 ); wing membrane infuscate, pterostigma and veins brown ( Figs 18a, 18b View FIGURE 18 ).

Male. Length of body of male 7.2–7.8 mm, of fore wing of male 6.3–6.8 mm; antenna of male with 44–46 antennomeres; propodeum reddish brown medially or entirely black.

Biology. The type series has been reared from Semanotus bifasciatus (Motschulsky, 1875) ( Coleoptera : Cerambycidae ).

Distribution. China (Guangdong).

Etymology. Named “promiscuus” (Latin for “mixed, blended”) because the metasoma shows a combination of different sculpture.
