Figs 17–18
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); 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); clypeus height: inter-tentorial distance: tentorio-ocular distance = 1: 3: 2; clypeus sparsely long setose; eye nearly immarginated (Fig. 18g); face 0.8 × longer than wide, densely long setose and coarsely sculptured (Fig. 18g); 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); 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).
Mesosoma. Length of mesosoma 1.5 × its height (Fig. 18c); notauli only impressed anteriorly (Fig. 18d); mesoscutum sparsely punctate, along notauli with long setae (Fig. 18d); scutellar sulcus deep, moderately wide, and with crenulae (Fig. 18d); scutellum sparsely punctate, with dense short setae posteriorly; metanotum strongly convex medially, and with a short median carina anteriorly (Fig. 18d); propodeum largely smooth, but with a few short longitudinal carinae latero- and medio-posteriorly, sparsely setose medially, and densely long setose laterally (Fig. 18d).
Wings. Fore wing (Fig. 18a): 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): 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); first tergite with developed lateral carinae, lateral grooves crenulate (Fig. 18e); second tergite largely sculptured (Fig. 18e); 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); second suture wide and deep, crenulate, straight medially (Fig. 18e); third–fifth tergites with some strong punctures, with weak antero-lateral areas, and crenulate transverse subposterior groove (Fig. 18e); sixth and seventh tergites largely smooth; ovipositor sheath 0.6 × as long as fore wing.
Colour. Head and mesosoma largely reddish yellow (Fig. 17); antenna, eyes, mandible apically (Fig. 18g), and propodeum laterally and medio-basally blackish brown (Fig. 18d); legs and metasoma blackish brown (Figs 18e, 18f); ovipositor sheath black (Fig. 17); wing membrane infuscate, pterostigma and veins brown (Figs 18a, 18b).
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.
