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 View FIGURE 2 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 5: 13: 14; clypeus with two especially long setae submedially; eye weakly emarginated ( Fig. 2g View FIGURE 2 ); face weakly sculptured medially, with sparse weak punctures laterally, and with dense long setae ( Fig. 2g View FIGURE 2 ); 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 View FIGURE 2 ); 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 View FIGURE 2 ).
Mesosoma. Length of mesosoma 1.8 × its height ( Fig. 2c View FIGURE 2 ); notauli shallow posteriorly but complete ( Fig. 2d View FIGURE 2 ); mesoscutum smooth and densely short setose posteriorly ( Fig. 2d View FIGURE 2 ); scutellar sulcus deep, rather narrow, with crenulae ( Fig. 2d View FIGURE 2 ); scutellum smooth, with dense short setae; metanotum moderately convex medially ( Fig. 2d View FIGURE 2 ); propodeum largely smooth, without medio-longitudinal carina or groove, and sparsely setose medially, with dense long setae laterally ( Fig. 2d View FIGURE 2 ).
Wings. Fore wing ( Fig. 2a View FIGURE 2 ): 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 View FIGURE 2 ): 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 View FIGURE 2 ); first tergite with a relatively long medio-longitudinal carina but absent anteriorly, and with developed lateral carinae, lateral grooves wide and crenulate ( Fig. 2j View FIGURE 2 ); 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 View FIGURE 2 ); second suture deep, crenulate, nearly straight medially ( Fig. 2e View FIGURE 2 ); 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 View FIGURE 2 ); fifth–seventh tergites smooth ( Fig. 2e View FIGURE 2 ); hypopygium acute apically, reaching beyond level of apex of metasoma; ovipositor sheath 1.2 × as long as fore wing.
Colour. Largely black ( Fig. 1 View FIGURE 1 ); head largely yellow, antenna, mandible apically, frons medially and stemmaticum black ( Figs 2g, h View FIGURE 2 ); propleuron yellow ( Fig. 2c View FIGURE 2 ); fore leg largely yellow but tarsus yellowish brown (telotarsus black) and claws black, middle femur and tibia yellow ( Fig. 26f View FIGURE 26 ); wing membrane yellow, but pale brown apically, fore wing with irregular pale brown stigmal spot, pterostigma yellow, and veins dark brown ( Figs 26a, 26b View FIGURE 26 ).
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”.
