( Figs 20–26View FIGURES 20–26)

Material examined. Holotype, 1♀, China, Yunnan prov., Diqing City, Deqin County, Benzilan , 28°14′4″N, 99°16′36″E, 2286 m, 29.VII.2011, Xuefei Zhang ( CQNU).GoogleMaps 

Description. Female ( Fig. 20View FIGURES 20–26). Body length 9.11 mm. Black, following parts brownish yellow: clypeus except apical margin and a central black spot ( Fig. 21View FIGURES 20–26), mandible, a short band along lower inner eye orbit, inter-antennal spot, scape and pedicle ventrally; following parts ferruginous: an elongated band on temple, most of pronotum, upper part of anterior vertical face of pronotum, large spot on mesepisternum, tegula except a translucent spot on center, parategula, metanotum ( Fig. 20View FIGURES 20–26), posterolateral band of propodeum, apical bands of terga I–V and sterna II–V (apical bands of segment IV-V widened in the middle), segment VI wholly ( Figs 23, 25View FIGURES 20–26), apical spots on all coxae, apical bands of fore and mid femora, apical band of hind femur outside, all tibiae and tarsi; wings lightly brown. Body with dense and pale brown setae, setae on propodeum relatively longer than those of other parts.

Head. Clypeus 1.20× as wide as long in frontal view, with large and sparse punctures, apex slightly emarginate, emargination width about 1/5 of clypeal width ( Fig. 21View FIGURES 20–26); mandible normal, third tooth of mandible without one deep incision; frons, vertex and temple with coarse punctures, punctures on frons somewhat reticulate and relatively denser than those on other parts of head ( Fig. 21View FIGURES 20–26); smooth area around cephalic foveae not extended to outer margin of posterior ocellus ( Fig. 22View FIGURES 20–26).

Mesosoma. Mesosoma with coarse punctures, punctures on pronotum and mesonotum coarser than those on other parts of mesosoma; pronotal humeral angle blunt ( Fig. 22View FIGURES 20–26); setae at upper part of mesonotum not brush-like in lateral view; mesopleuron with sparse punctures ( Fig. 26View FIGURES 20–26); scutellum flat, rectangle and with dense punctures, punctures at the base sparser; metanotum coarsely punctate, slightly concave mesally; dorsal face of propodeum with honeycomb punctures, lateral face coriaceous ( Fig. 26View FIGURES 20–26); posterior face of propodeum with thin transverse striae and distinctly median longitudinal carina ( Fig. 24View FIGURES 20–26); ventral side of fore trochanter and femur with short and dense setae.

Metasoma. Tergum I ( Fig. 23View FIGURES 20–26) a little wider than long, 1.18× as wide as long in dorsal view, with dense punctures, punctures at base much denser, coarser and bigger than those at other parts of metasoma; tergum II with dense punctures, punctures wholly smaller than those of tergum I, apex with deeper and denser punctures than other parts of tergum II, and at apex with one row of deep and dense forming a transverse groove, and with a narrow apical lamella behind groove, apical lamella almost not bent backward up ( Fig. 23View FIGURES 20–26); sternum II ( Fig. 25View FIGURES 20–26) convex basally, and with coarse and medium dense punctures, punctures almost uniform except one row of apical punctures; punctures at visible part of metasomal segment III slightly denser than those of segment II.

Male. Unknown.

Distribution. China (Yunnan).

Remarks. This species is similar to A. d. delphinalis Blüthgen, 1953  , in smooth area around cephalic foveae not extended to outer margin of posterior ocellus ( Figs 22View FIGURES 20–26, 41), tergum II with medium and dense punctures, apex with deeper and denser punctures than other parts of tergum II, and without a bent apical lamella ( Figs 23View FIGURES 20–26, 48). It differs from A. d. delphinalis  and other members of the genus by the following combination of characters: body with abundant ferruginous markings ( Fig. 20View FIGURES 20–26), clypeus a little wider than long (1.20×) ( Fig. 21View FIGURES 20–26) (much wider than long, 1.44×in Fig. 39 of A. d. delphinalis  ), flagellum wholly black, and tergum I ( Fig. 23View FIGURES 20–26) a little wider than long (1.18×) (much wider than long, 1.43× in Fig. 48 of A. delphinalis  ).

Etymology. The specific name refers to its type locality: Diqing, China.
