Figs 1–2
Type material. Holotype. CHINA • ♀; Hunan Province, Xinning; 5.Jul.1980; X.W. Tong leg.; host: larva of Callidium vilosulum Fairmaire, 1899; ZJUH 846548.
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 pattern, third–fifth metasomal tergites with yellow spots, and sixth and seventh tergites yellowish white (uniformly blackish brown in C. promiscuus); fifth metasomal tergite with transverse subposterior groove weak and incomplete, absent medially (complete and crenulate); ovipositor sheath shorter, 0.2 × as long as fore wing (0.6 × as long as fore wing); third–fifth metasomal tergites largely smooth, only sparsely and finely punctate (coarsely punctate); temples relatively short, in dorsal view length of eye 1.6 × temple and temples linearly narrowed behind eyes (temples relatively long, in dorsal view length of eye 1.3 × temple, temples subparallel-sided behind eyes).
Description. Holotype, ♀, length of body 6.3 mm, of fore wing 6.1 mm, of ovipositor sheath 1.0 mm.
Head. Antenna with 54 antennomeres; apical flagellomere acute, 2.2 × longer than its maximum width (Fig. 2k); first flagellomere 1.5 × longer than wide, 1.2 and 1.4 × longer than second and third, respectively, the latter being 1.1 × longer than wide; malar suture with dense setae and some weak punctures; clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 11: 8; clypeus densely short setose; eye weakly emarginated (Fig. 2g); face 0.8 × longer than its width, largely smooth, except for some weak punctures, with short setae and (Fig. 2g); eye height: shortest distance between eyes: head width = 12: 11: 23; frons smooth, concave behind antennal sockets, with a strong median groove (Fig. 2i); vertex smooth, with sparse short setae; shortest distance between posterior ocelli: narrower diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 4: 3: 9; in dorsal view length of eye 1.6 × temple; temples linearly narrowed behind eyes (Fig. 2h).
Mesosoma. Length of mesosoma 1.7 × its height (Fig. 2c); notauli only impressed anteriorly (Fig. 2d); mesoscutum mostly smooth and sparsely setose (Fig. 2d); scutellar sulcus deep, moderately wide, with crenulae (Fig. 2d); scutellum smooth, with some setae; metanotum strongly convex medially, and short median carina somewhat protruding (Fig. 2d); propodeum largely smooth, without medio-longitudinal carina or groove, but with a few short carinae posteriorly, and sparsely setose medially, with dense long setae laterally (Fig. 2d).
Wings. Fore wing (Fig. 2a): SR1: 3-SR: r = 33: 20: 8; 1-SR+M strongly curved after arising from 1-M; 2-SR: 3-SR: r-m = 11: 20: 10; angle between 1-SR and C+SC+R about 80°; r-m rather weakly curved; cu-a interstitial. Hind wing (Fig. 2b): SC+R1: 2-SC+R: 1r-m = 15: 3: 8.
Legs. Length of fore femur: tibia: tarsus = 21: 25: 39; length of hind femur: tibia: basitarsus = 31: 43: 16; length of femur, tibia and basitarsus of hind leg 4.3, 8.1 and 5.0 × their maximum width, respectively; hind tibial spurs 0.2 and 0.3 × as long as hind basitarsus.
Metasoma. Length of first tergite 1.1 × its apical width, smooth medio-basally, median area convex, reticulate, but smooth medio-posteriorly (Fig. 2e); first tergite with a rather short medio-longitudinal carina posteriorly, and with developed lateral carinae, lateral grooves crenulate (Fig. 2e); apical width of second tergite 2.4 × its median length, triangular medio-basal area of second tergite smooth, attached to medio-longitudinal carina, absent near posterior margin of second tergite; antero-lateral areas of second tergite smooth, oblique anterior grooves deep and crenulate; second tergite coarsely sculptured, except for medio-basal, antero-lateral areas and medio-posteriorly (Fig. 2e); second suture deep, crenulate, straight medially (Fig. 2e); third–fifth tergites with antero-lateral areas, and with transverse subposterior grooves, but not impressed medially (Fig. 2e); third–seventh tergites largely smooth, except some weak punctures (Fig. 2e); ovipositor sheath 0.2 × as long as fore wing.
Colour. Head and mesosoma largely yellow (Fig. 1); flagellomeres of antenna, eyes and mandible apically blackish brown; fore and middle legs yellow (except for yellowish brown claws), hind leg yellowish brown (second segment of trochanter somewhat paler; Fig. 2f); metasoma largely yellowish brown (Fig. 2e); third–fifth metasomal tergites medially and fourth–fifth tergites laterally yellow, sixth and seventh tergites whitish yellow (Fig. 2e); ovipositor sheath black; wing membrane infuscate, pterostigma and veins dark yellow or yellowish brown (Figs 2a, 2b).
Biology. The holotype has been reared from a larva of Callidium vilosulum Fairmaire, 1899 (Coleoptera: Cerambycidae).
Distribution. China (Hunan).
Etymology. Named after the short ovipositor sheath: “brachys” is Greek for “short” and “oura” is Greek for “tail”.
