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); clypeus height: inter-tentorial distance: tentorio-ocular distance = 6: 11: 10; clypeus with two special long setae submedially; eye not emarginate (Fig. 18g); face smooth medially, with sparse weak punctures laterally, and with dense long setae especially laterally (Fig. 18g); 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); 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).
Mesosoma. Length of mesosoma 1.7 × its height (Fig. 18c); notauli only impressed anteriorly (Fig. 18d); mesoscutum smooth and sparsely short setose (Fig. 18d); scutellar sulcus deep, moderately narrow and crenulate (Fig. 18d); scutellum smooth, with dense short setae posteriorly; metanotum moderately convex medially (Fig. 18d); propodeum largely smooth, without medio-longitudinal carina or groove, and sparsely setose medially, with dense long setae laterally (Fig. 18d).
Wings. Fore wing (Fig. 18a): 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): 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); first tergite without medio-longitudinal carina, with weak lateral carinae, lateral grooves relatively wide and sparsely crenulate (Fig. 18j); 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); second suture deep, crenulate, more or less straight medially (Fig. 18e); antero-lateral areas of third tergite weakly developed (Fig. 18e); third–seventh tergites smooth (Fig. 18e); 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); head largely yellow, antenna, mandible apically, stemmaticum black (Figs 18g, 18h); propleuron and pronotum yellow (Fig. 18c); 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); 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).
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”.
