Type material. Holotype. ♀, China, Yunnan Prov., Xishuangbanna Mengla, 620–650m, 9.VII.1959, Pu Fuji, No. IOZ(E)1964629 (IZCAS). Paratypes. ♀, China, Yunnan Prov., Xishuangbanna Mengla, 620–650m, 9.VII.1959, Pu Fuji, No. IOZ(E)1964620 (IZCAS); ♀, China, Yunnan Prov., Road Cheli-Menghai, 720m, 23.IV.1957, Pu Fuji, No. IOZ(E)1964549 (IZCAS).
Diagnosis. This new species is very similar to A. maculipennis sp. nov., but can be separated from the latter by the following characters: mesoscutum black (yellow, but lobes with a black spot in A. maculipennis); fore wing membrane without a black spot (fore wing membrane with a black spot from vein 1-SR to middle of first discal cell); frons black (yellow); ovipositor sheath 1.2 × as long as fore wing (about as long as fore wing).
Description. Holotype, ♀, length of body 10.8 mm, of fore wing 11.0 mm, of ovipositor sheath 13.3 mm.
Head. Antenna incomplete, remaining part with 18 antennomeres; median flagellomeres 1.1 × longer than its width; first flagellomere 1.3 and 1.4 × longer than second and third, respectively, the latter being 1.2 × longer than wide; length of maxillary palp 0.8 × height of head; malar suture with some short setae and weakly sculptured (Fig. 2g); clypeus height: inter-tentorial distance: tentorio-ocular distance = 5: 13: 14; clypeus with two especially long setae submedially; eye weakly emarginated (Fig. 2g); face weakly sculptured medially, with sparse weak punctures laterally, and with dense long setae (Fig. 2g); eye height: shortest distance between eyes: head width = 26: 32: 68; frons largely smooth except for a few weak punctures, strongly concave behind antennal sockets, with a median groove (Fig. 2h); vertex largely smooth except for a few weak punctures, with sparse short setae; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 3: 4: 11; length of malar space equal to basal width of mandible; in dorsal view eye as long as temple; temples subparallel behind eyes (Fig. 2h).
Mesosoma. Length of mesosoma 1.8 × its height (Fig. 2c); notauli shallow posteriorly but complete (Fig. 2d); mesoscutum smooth and densely short setose posteriorly (Fig. 2d); scutellar sulcus deep, rather narrow, with crenulae (Fig. 2d); scutellum smooth, with dense short setae; metanotum moderately convex medially (Fig. 2d); propodeum largely smooth, without medio-longitudinal carina or groove, and sparsely setose medially, with dense long setae laterally (Fig. 2d).
Wings. Fore wing (Fig. 2a): SR1: 3-SR: r = 41: 27: 6; 1-SR+M weakly curved after arising from 1-M, 1.3 × longer than 1-M; 2-SR: 3-SR: r-m = 13: 27: 9; m-cu straight, 2.7 × longer than 2-SR+M; cu-a slightly postfurcal. Hind wing (Fig. 2b): 1r-m weakly curved; SC+R1: 2-SC+R: 1r-m = 15: 4: 11.
Legs. Length of fore femur: tibia: tarsus = 26: 31: 58; length of hind femur: tibia: basitarsus = 38: 66: 25; length of femur, tibia and basitarsus of hind leg 2.9, 9.3 and 6.2 × their maximum width, respectively.
Metasoma. Length of first tergite 1.4 × its apical width, smooth medio-basally, median area convex, reticulate (Fig. 2j); first tergite with a relatively long medio-longitudinal carina but absent anteriorly, and with developed lateral carinae, lateral grooves wide and crenulate (Fig. 2j); triangular medio-basal area of second tergite smooth, attached to medio-longitudinal carina which with a few transverse crenulae laterally, absent near posterior margin of second tergite; oblique anterior grooves of second tergite wide, deep and strongly crenulate; second tergite coarsely sculptured, except for medio-basal area and antero-laterally (Fig. 2e); second suture deep, crenulate, nearly straight medially (Fig. 2e); antero-lateral areas of third tergite strongly convex and rugose; third tergite largely with longitudinal and oblique striae except for antero-lateral areas and posteriorly; fourth tergite largely smooth but anterolateral areas weakly rugose (Fig. 2e); fifth–seventh tergites smooth (Fig. 2e); hypopygium acute apically, reaching beyond level of apex of metasoma; ovipositor sheath 1.2 × as long as fore wing.
Colour. Largely black (Fig. 1); head largely yellow, antenna, mandible apically, frons medially and stemmaticum black (Figs 2g, h); propleuron yellow (Fig. 2c); fore leg largely yellow but tarsus yellowish brown (telotarsus black) and claws black, middle femur and tibia yellow (Fig. 26f); wing membrane yellow, but pale brown apically, fore wing with irregular pale brown stigmal spot, pterostigma yellow, and veins dark brown (Figs 26a, 26b).
Variation. Length of body of female 10.8–12.1 mm, of fore wing of female 10.9–11.5 mm, and of ovipositor sheath 12.8–13.4 mm; antenna of female with 60 antennomeres; apical flagellomere slightly acute, 2.1 × longer than its maximum width; penultimate flagellomere 1.4 × longer than its maximum width, and 0.7 × as long as apical flagellomere; length of mesosoma 1.5–1.8 × its height; middle legs sometimes uniformly black.
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the strong and long medio-longitudinal carina of second metasomal tergite: “carinatus” is Latin for “with carina”.
