Figs 23–24
Type material. Holotype. ♀, China, Xizang Prov., Motuo, 1420m, 14.VI.1980, Jin Gentao, Wu Jianyi, No. 34202258 (SHEM).
Diagnosis. This new species is very similar to C. maculithorax sp. nov., but can be separated from the latter by the following characters: mesoscutum yellowish brown, without black spots (mesoscutum yellow and with 3 black spots in C. maculithorax); anterior half of second metasomal tergite largely smooth, only with some short striae near basal areas (more or less longitudinally striate behind smooth basal areas); hind leg entirely black (hind coxa, trochanter, femur (except apically) and claws blackish brown, remainder of hind legs yellow); median area of first tergite smooth except for low median carina and few striae (largely longitudinally striate); fore wing vein cu-a interstitial (slightly postfurcal).
Description. Holotype, ♀, length of body 11.6 mm, of fore wing 12.9 mm, of ovipositor sheath 10.6 mm.
Head. Antenna 0.9 × as long as fore wing, with 70 antennomeres; apical flagellomere acute, scapus slender, parallel-sided and distinctly protruding ventro-apically, with narrow indistinct apical ledge at inner side and basally gradually narrowed, its ventral setae erect (Figs 24l, 24m); first, second and penultimate flagellomeres 1.7, 1.1 and 1.8 × their maximum width, respectively; length of maxillary palp 0.9 × height of head; eye not emarginate (Fig. 24g); face weakly and evenly convex, remotely finely punctate and with long erect yellowish setae; clypeus flat, superficially rugulose, dorsally with weak carina and ventral margin thin and lamelliform protruding, with a row of long yellowish setae ventrally; hypoclypeal depression 0.5 × as wide as minimum width of face (Fig. 24g); frons shallowly concave behind antennal sockets, with deep median groove, smooth except for a few punctures laterally (Fig. 24h); vertex smooth except for few punctures and weakly convex, glabrous; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 18: 7: 6; in dorsal view length of eye 1.6 × temple; temples weakly narrowed behind eyes, with spaced setiferous punctures and long setae (Fig. 24h); malar suture present and curved; length of malar space 0.8 × basal width of mandible; mandible twisted and with two wide teeth.
Mesosoma. Length of mesosoma 1.6 × its height (Fig. 24c); side of pronotum shiny and smooth; propleuron with spaced punctures; pronotum vertical anteriorly and with a shallow groove and no antescutal depression; mesopleuron largely smooth and glabrous, anteriorly weakly punctate and sparsely setose; mesosternal sulcus smooth and narrow; metapleuron weakly punctate and with long setae, convex; mesoscutum glabrous except some setae near notaulic courses, shiny and smooth; notauli shallowly impressed, smooth; scutellar sulcus present and with distinct crenulae (Fig. 24d); scutellum nearly flat anteriorly and smooth; side of scutellum smooth; metanotum medio-anteriorly with short carina, posteriorly evenly convex and smooth (Fig. 24d); propodeum smooth, with many long setae and evenly convex medially, medio-apically smooth in lateral view (Fig. 24j).
Wings. Fore wing (Fig. 24a): m-cu 0.8 × as long as 1-M; 1-SR+M sharply angled after arising from 1-M, 1.5 × as long as 1-M; 3-SR weakly curved, and SR1 straight; r: 3-SR: SR1 = 6: 33: 43; 2-SR: 3-SR: r-m = 4: 11: 4; r-m largely sclerotised; 1-CU1 widened and 0.06 × 2-CU1; cu-a vertical and interstitial; CU1b narrower than 3-CU1. Hind wing (Fig. 24b): with 3 coarse subbasal bristles on C+SC+R and with 3 hamuli on R1; SR weakly curved basally and marginal cell parallel-sided apically; subbasal cell near cu-a setose; 1r-m straight and 0.8 × as long as SC+R1; 2-SC+R 2.5 × longer than wide.
Legs. Tarsal claws simple and with long bristly setae ventrally; fore tarsus 1.3 × as long as fore tibia and tibia bristly setose and pimply anteriorly; length of femur, tibia and basitarsus of hind leg 3.5, 10.1 and 6.4 × their maximum width, respectively; hind tibia with dense appressed setae (Fig. 24f); hind tibial spurs 0.3 and 0.4 × as long as hind basitarsus; inner side of hind tibia and tarsus densely bristly setose.
Metasoma. Length of first tergite 1.2 × its apical width, medial area low anteriorly, dorso-lateral carinae strongly developed, medial area largely smooth except for median carina and a few longitudinal striae (Fig. 24k); second tergite largely smooth except for median carina connected to nearly rhombical medio-basal area and some crenulae near medio-basal area and outer side of antero-lateral triangular areas, and crenulate wide oblique anterior grooves (Fig. 24e); second metasomal suture strongly crenulate, laterally narrowed and oblique (Fig. 24e); medially second tergite clearly longer than third tergite; maximum width of third tergite 4.0 × its medial length; third–fifth tergites largely smooth and with smooth antero-lateral grooves (but third tergite weakly crenulate) and transverse subposterior groove (but fifth tergite weakly crenulate laterally) (Fig. 24e); ovipositor sheath 0.82 × as long as fore wing and 0.91 × body; hypopygium just surpassing apex of metasoma.
Colour. Largely black (Fig. 23); head largely yellow, antenna (including entire scapus), eye, mandible apically and stemmaticum black (Figs 24g, 24h); pronotum, propleuron, tegula, mesoscutum, scutellum, mesosternum (except for median area) and metanotum posteriorly yellowish brown (Figs 24c, 24d); legs largely black, fore leg (but fourth and fifth tarsomeres infuscate) and middle tibia yellow, middle tarsus (but telotarsus black) dark brown (Fig. 24f); apical 0.2 of pterostigma dark brown, remainder of pterostigma and wing membrane yellow, but fore wing with irregular stigmal spot up to vein CU1b, including dark brown veins 1-SR, 1-SR+M, m-cu, 3-CU1 and CU1b and apically wings with wide infuscate area; remainder of veins brownish yellow (Figs 24a, 24b).
Biology. Unknown.
Distribution. China (Xizang).
Etymology. Named after the metasomal tergites uniformly black: “nigra” is Latin for “black” and “abdominalis” is Latin for “of the abdomen”.
