Type material. Holotype. ♀, China, Yunnan Prov., Xishuangbanna Meng’a , 1050–1080m, 8.VIII.1958, Pu Fuji, No. IOZ(E)1964566 ( IZCAS) . Paratypes. 1♂, China, Yunnan Prov., Xishuangbanna Menghai , 1100m, 12.VIII.1957, Wang Shuyong, No. IOZ(E)1964581 ( IZCAS) ; 1♂, China, Yunnan Prov., Xishuangbanna Meng’a , 1050–1080m, 6.VIII.1958, Pu Fuji, No. IOZ(E)1964567 ( IZCAS) .
Diagnosis. This new species is very similar to A. grandis Wang et Chen, 2009 , but can be separated from the latter by the following characters: mesoscutum black (yellow in A. grandis , sometimes lateral lobes blackish brown posteriorly); first metasomal tergite black, second metasomal tergite black medio-basally and laterally, remainder of tergite yellow brown, third and fourth metasomal tergites black, yellow medially, fifth–seventh metasomal tergites yellow (metasomal tergites entirely black); frons black (frons yellow); second metasomal tergite largely smooth (largely sculptured).
Description. Holotype, ♀, length of body 10.2 mm, of fore wing 9.8 mm, of ovipositor sheath 10.5 mm.
Head. Antenna incomplete, remaining part with 47 antennomeres; median flagellomeres as long as wide; first flagellomere 1.1 and 1.2 × longer than second and third, respectively, the latter being 1.6 × longer than wide; length of maxillary palp 0.7 × height of head; malar suture with some short setae and superficially sculptured ( Fig. 18g View FIGURE 18 ); clypeus height: inter-tentorial distance: tentorio-ocular distance = 6: 11: 10; clypeus with two special long setae submedially; eye not emarginate ( Fig. 18g View FIGURE 18 ); face smooth medially, with sparse weak punctures laterally, and with dense long setae especially laterally ( Fig. 18g View FIGURE 18 ); eye height: shortest distance between eyes: head width = 4: 5: 11; frons largely smooth except for some weak punctures, strongly concave behind antennal sockets, with a median groove ( Fig. 18h View FIGURE 18 ); vertex largely smooth, with some punctures and dense long setae laterally; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 2: 3: 5; length of malar space equal to basal width of mandible; in dorsal view eye as long as temple; temples weakly expanded behind eyes ( Fig. 18h View FIGURE 18 ).
Mesosoma. Length of mesosoma 1.7 × its height ( Fig. 18c View FIGURE 18 ); notauli only impressed anteriorly ( Fig. 18d View FIGURE 18 ); mesoscutum smooth and sparsely short setose ( Fig. 18d View FIGURE 18 ); scutellar sulcus deep, moderately narrow and crenulate ( Fig. 18d View FIGURE 18 ); scutellum smooth, with dense short setae posteriorly; metanotum moderately convex medially ( Fig. 18d View FIGURE 18 ); propodeum largely smooth, without medio-longitudinal carina or groove, and sparsely setose medially, with dense long setae laterally ( Fig. 18d View FIGURE 18 ).
Wings. Fore wing ( Fig. 18a View FIGURE 18 ): SR1: 3-SR: r = 36: 28: 6; 1-SR+M more or less straight, 1.4 × longer than 1-M; 2-SR: 3-SR: r-m = 9: 28: 9; m-cu straight, 2.2 × longer than 2-SR+M; cu-a more or less interstitial. Hind wing ( Fig. 18b View FIGURE 18 ): 1r-m slightly curved; SC+R1: 2-SC+R: 1r-m = 38: 5: 21.
Legs. Length of fore femur: tibia: tarsus = 26: 28: 45; length of hind femur: tibia: basitarsus = 30: 48: 17; length of femur, tibia and basitarsus of hind leg 3.0, 9.6 and 5.7 × their maximum width, respectively.
Metasoma. Length of first tergite 1.7 × its apical width, smooth medio-basally, median area convex, and weakly rugose posteriorly ( Fig. 18j View FIGURE 18 ); first tergite without medio-longitudinal carina, with weak lateral carinae, lateral grooves relatively wide and sparsely crenulate ( Fig. 18j View FIGURE 18 ); triangular medio-basal area of second tergite very large and smooth, defined by two oblique long and sparsely crenulate grooves laterally, absent near posterior margin of second tergite, and without medio-longitudinal carina; antero-lateral areas of second tergite smooth, oblique anterior grooves weakly and sparsely crenulate; second tergite largely smooth except for crenulate grooves ( Fig. 18e View FIGURE 18 ); second suture deep, crenulate, more or less straight medially ( Fig. 18e View FIGURE 18 ); antero-lateral areas of third tergite weakly developed ( Fig. 18e View FIGURE 18 ); third–seventh tergites smooth ( Fig. 18e View FIGURE 18 ); hypopygium acute apically, reaching far beyond level of apex of metasoma; ovipositor sheath 1.1 × as long as fore wing.
Colour. Largely black ( Fig. 17 View FIGURE 17 ); head largely yellow, antenna, mandible apically, stemmaticum black ( Figs 18g, 18h View FIGURE 18 ); propleuron and pronotum yellow ( Fig. 18c View FIGURE 18 ); fore coxa yellow, fore tarsus yellowish brown; second metasomal tergite yellow but medio-basal and antero-lateral areas black, third and fourth tergites yellow medially, fifth–seventh tergites yellow ( Fig. 18e View FIGURE 18 ); wing membrane largely infuscate or smoky gray, becoming paler apically, fore wing with a pale oblique stripe at level of vein 2-SR+M, pterostigma and veins blackish brown ( Figs 18a, 18b View FIGURE 18 ).
Male. Length of body of male 8.7–9.2 mm, of fore wing of male 7.1–7.6 mm; antenna of male with 49 antennomeres; apical flagellomere slightly acute; length of mesosoma 1.7 × its height; fore wing vein 3-SR 1.5 × and 2.8 × longer than vein SR1 and 2-SR, respectively; fifth metasomal tergite sometimes black posterior-laterally.
Biology. Unknown.
Distribution. China (Yunnan).
Etymology. Named after the dense long setae (especially laterally) of the face: “setosus” is Latin for “bristly”.
