Type material. Holotype ♁, CHINA: Hainan Province: Baoting County, Jiuyi Mountain (25°16′43.12″N, 111°56′45.6″E, 734 m a.s.l.), 27 Apr. 2021, leg. Yannan Mu.

Etymology. The specific name is derived from the type locality; noun in apposition.

Diagnosis. This new species can be separated from other congeneric species except A. ornata (Deeleman-Reinhold, 2001) by the smooth prolateral margin of the retrolateral tibial apophysis without a branch, but differing from A. ornata by: 1) the shorter embolus and tegular apophysis (vs long, cf. Fig. 1D and fig. 678 in Deeleman-Reinhold [2001]); and 2) the presence of a conductor (vs without a conductor, cf, Fig. 1E and fig. 678 in Deeleman-Reinhold [2001]).

Coloration. Carapace yellow, with longitudinal black stripes along marginal of carapace. Abdomen gray, anterior with narrow yellow dorsal scutum anteriorly, laterally with black flanks, posteriorly with black transverse stripe (Fig. 1A, B). Legs yellow, femora, tibia and metatarsi with black annuli.

Palp as in Figs 1C–F, 2. Femoral apophysis smooth, with slightly swollen near tip. Retrolateral tibial apophysis with smooth prolateral margin, without branches, tapering from base to blunt tip; dorsal tibial apophysis narrower than retrolateral tibial apophysis, with curved tip; ventral tibial hump conspicuous, round. Tegulum oval, narrower than cymbium; tegular apophysis small, with sharp tip. Sperm duct distinct, tapering from retrolateral side of tegulum to embolus. Embolus short, directed distoventrally. Conductor membranous, with thin base and wide tip.
