Figs 11–12

Type material. Holotype. CHINA • ♀; Yunnan Province, Jinggu ; 930m; 13 Apr. 1955; Keleirangluofusiji leg.; IZCAS IOZ (E)1964535.

Diagnosis. This new species is very similar to C. kirbyi ( Cameron, 1905) , but can be separated from the latter by the following characters: frons medially up to area surrounding stemmaticum black (head yellow and without black spot surrounding stemmaticum in C. kirbyi ); second metasomal tergite largely with longitudinal striae (coarsely reticulated sculptured); fore wing vein 1-SR+M more or less straight (curved); face coarsely punctate (irregularly rugose); hind wing vein SC+R1 1.1 × as long as vein 1r-m (longer, 1.8 ×).

Description. Holotype, ♀, length of body 12.8 mm, of fore wing 11.6 mm, of ovipositor sheath 9.5 mm.

Head. Antenna incomplete, with 82 antennomeres remaining; first flagellomere 1.1 × longer than its maximum width, 1.2 and 1.3 × longer than second and third, respectively, the latter as long as wide; malar suture developed and sparsely short setose ( Fig. 12i ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 4: 9: 5; clypeus sparsely short setose; eye not emarginated ( Fig. 12g ); width of hypoclypeal depression 1.3 × its height; face 1.1 × longer than wide, coarsely punctate, with long setae laterally ( Fig. 12g ); eye height: shortest distance between eyes: head width = 19: 17: 34; frons smooth, weakly concave behind antennal sockets, with a strong median groove ( Fig. 12h ); 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 = 1: 1: 2; in dorsal view length of eye twice temple; temples strongly narrowed behind eyes ( Fig. 12h ).

Mesosoma. Length of mesosoma 2.1 × its height ( Fig. 12c ); notauli only impressed anteriorly ( Fig. 12d ); mesoscutum largely glabrous, but with a few long setae posteriorly and along notauli ( Fig. 12d ); scutellar sulcus deep and sparsely crenulate ( Fig. 12d ); scutellum with a few weak punctures medially; metanotum strongly convex medially, with a short carina medio-anteriorly ( Fig. 12d ); propodeum largely smooth except for some sparse weak punctures medially, without medio-longitudinal carina or groove, sparsely setose medially, and densely long setose laterally ( Fig. 12d ).

Wings. Fore wing ( Fig. 12a ): pterostigma 2.9 × longer than wide; SR1: 3-SR: r = 28: 21: 5; 1-SR+M more or less straight; 2-SR: 3-SR: r-m = 9: 21: 10; angle between 1-SR and C+SC+R about 80°; cu-a narrowly postfurcal, weakly oblique anteriorly. Hind wing ( Fig. 12b ): SC+R1: 2-SC+R: 1r-m = 17: 5: 15.

Legs. Length of fore femur: tibia: tarsus = 25: 29: 34; length of hind femur: tibia: basitarsus = 35: 61: 21; length of femur, tibia and basitarsus of hind leg 3.7, 9.4 and 5.2 × their maximum width, respectively; hind tibial spurs 0.3 and 0.5 × as long as hind basitarsus.

Metasoma. Length of first metasomal tergite 1.1 × its apical width, median area convex and with medio-longitudinal carina and medially with some longitudinal striae, lateral grooves with a few sparse crenulae anteriorly and posteriorly ( Fig. 12j ); second tergite largely with longitudinal striae except posteriorly, triangular medio-basal area of second tergite smooth, attached to medio-longitudinal carina apically, latter not reaching posterior margin of second tergite ( Fig. 12e ); apical width of second tergite 1.4 × its median length, antero-lateral areas of second tergite smooth, anterior grooves crenulate ( Fig. 12e ); second suture wide and deep, crenulate, nearly straight medially ( Fig. 12e ); third tergite largely smooth except for longitudinal striae medio-basally, with antero-lateral areas and oblique anterior grooves smooth, without subposterior groove, densely setose laterally ( Fig. 12e ); fourth–sixth tergites coarsely sculptured ( Fig. 12e ); third–fifth tergites with antero-lateral areas (but of fifth tergite weak) ( Fig. 12e ); fourth–seventh tergites smooth, densely setose; ovipositor sheath 0.8 × as long as fore wing.

Colour. Largely yellow ( Fig. 11 ); antenna, eyes and mandible apically blackish brown ( Fig. 12g ); frons medially up to area surrounding stemmaticum black, but not reaching eyes ( Fig. 12h ); pronotum, metapleuron ventrally and metasomal tergites infuscate ( Figs 12c, 12e ); claws and hind tarsus (except for first segment basally) blackish brown ( Fig. 12f ); basal half of wing membrane and of pterostigma yellow and remainder dark brown, stigmal spot dark brown, below basal half of pterostigma up to second discal cell anteriorly pale, veins dark brown or yellow ( Figs 12a, 12b ); ovipositor sheath black ( Fig. 11 ).

Biology. Unknown.

Distribution. China (Yunnan).

Etymology. Named after the small dorsal spot of the head, not reaching eyes or temple: “micros” is Greek “small” and for and “macula” is Latin for “spot”.
