Figs 7–8
Type material. Holotype. CHINA • ♀; Yunnan Province, Shancha river; 12 Apr. 1981; J.H. He leg.; ZJUH 811708.
Diagnosis. This new species is very similar to C. cingulicauda Enderlein, 1920, but can be separated from the latter by the following characters: fifth metasomal tergite coarsely sculptured (fifth metasomal tergite largely smooth in C. cingulicauda); sixth and seventh metasomal tergites entirely black (whitish yellow posteriorly); propodeum black (reddish brown); ovipositor sheath 0.4 × as long as fore wing (0.6 ×).
Description. Holotype, ♀, length of body 7.1 mm, of fore wing 7.2 mm, of ovipositor sheath 2.6 mm.
Head. Antenna with 54 antennomeres; apical flagellomere acute, with short spine, 2.3 × longer than its maximum width (Fig. 8l); first flagellomere 1.4 × 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 weakly sculptured and short setose (Fig. 8i); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 14: 7; clypeus sparsely short setose; eye hardly emarginated (Fig. 8g); width of hypoclypeal depression 1.2 × its height; face as long as wide, with some transverse carinae and long setae laterally, smooth medially (Fig. 8g); eye height: shortest distance between eyes: head width = 25: 20: 48; frons smooth, weakly concave behind antennal sockets, with a strong median groove (Fig. 8h); vertex largely glabrous except for some sparse short setae; minimum distance between posterior ocelli: minimum diameter of elliptical posterior ocellus: minimum distance between posterior ocellus and eye = 4: 3: 10; in dorsal view length of eye twice temple; temples strongly narrowed behind eyes (Fig. 8h).
Mesosoma. Length of mesosoma 1.8 × its height (Fig. 8c); notauli only impressed anteriorly (Fig. 8d); mesoscutum largely glabrous, but with long setae along notauli (Fig. 8d); scutellar sulcus deep and crenulate (Fig. 8d); scutellum with dense short setae posteriorly; metanotum strongly convex medially (Fig. 8d); propodeum smooth, without medio-longitudinal carina or groove, sparsely setose medially, and densely long setose laterally (Fig. 8d).
Wings. Fore wing (Fig. 8a): pterostigma 3.8 × longer than wide; SR1: 3-SR: r = 30: 25: 6; 1-SR+M strongly bent subbasally; 2-SR: 3-SR: r-m = 9: 25: 9; angle between 1-SR and C+SC+R about 75°; cu-a interstitial, vertical. Hind wing (Fig. 8b): SC+R1: 2-SC+R: 1r-m = 22: 8: 19.
Legs. Length of fore femur: tibia: tarsus = 23: 26: 36; length of hind femur: tibia: basitarsus = 32: 47: 17; length of femur, tibia and basitarsus of hind leg 4.0, 9.4 and 5.7 × their maximum width, respectively; hind tibial spurs 0.4 and 0.5 × as long as hind basitarsus.
Metasoma. Length of first metasomal tergite 1.7 × its apical width, median area convex and coarsely sculptured, medio-longitudinal carina absent, lateral grooves with some sparse crenulae anteriorly (Fig. 8j); second tergite largely densely sculptured, triangular medio-basal area of second tergite smooth, attached with medio-longitudinal carina apically, latter not reaching posterior margin of second tergite (Fig. 8e); apical width of second tergite 1.1 × its median length, antero-lateral areas of second tergite rather small and smooth, anterior grooves wide and crenulate (Fig. 8e); second suture wide and deep, crenulate, straight medially (Fig. 8e); apical width of third tergite 3.9 × its median length; third tergite with antero-lateral areas, subposterior groove short and present only laterally (Fig. 8e); third–sixth tergites coarsely sculptured; third–fifth tergites with antero-lateral areas (but of fifth tergite weak); fourth–sixth tergites with subposterior groove (but of fourth tergite absent medially) (Fig. 8e); seventh tergite largely smooth; fourth–seventh tergites densely setose posteriorly; ovipositor sheath 0.4 × as long as fore wing.
Colour. Head and mesosoma largely reddish yellow (Fig. 7); antenna, eyes, mandible apically, tegula, metanotum medially and propodeum black (Figs 8d, 8g); metapleuron ventrally (Fig. 8c), middle lobe and lateral lobes of mesoscutum with a black spot (Fig. 8d); legs black, fore femur and tibia, middle tibia apically yellowish or infuscate (Fig. 8f); metasoma and ovipositor sheath black (Figs 7, 8e); wing membrane greyish brown, fore wing with small dark brown stigmal spot up to vein 1-SR+M subbasally; pterostigma and veins blackish brown (Figs 8a, 8b).
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the relatively slender first metasomal tergite: “longus” and “tergum” is Latin for “long” and “back”, respectively.
