Figs 7–8

Type material. Holotype ♀, CHINA: Hunan Province: Zhuzhou City, Yanling County, Shennonggu National Forest Park (26.500841°N, 114.069715°E, 1060m a.s.l.), 9 May 2018, leg. Yannan Mu.

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

Diagnosis. This new species resembles A. zhejiangensis (Song & Kim, 1991) in having similar white PME, but can be recognized by: 1) the larger bursa (vs small, cf. Fig. 7D and fig. 3D in Liu et al. [2020]), 2) thicker, shorter copulatory ducts and thicker connecting tubes (vs copulatory ducts thin and long, connecting tubes thin, cf. Fig. 7D and fig. 3D in Liu et al. [2020]), 3) clavate-shaped, long and transverse spermathecae (vs globular, cf. Fig. 7D and fig. 3D in Liu et al. [2020]), and 4) thicker and shorter glandular appendages (vs thin and long, cf. Fig. 7D and fig. 3D in Liu et al. [2020]).

Carapace yellow, with indistinct radial groove beside fovea. Abdomen gray, with 4 pairs of black patterns and transverse black stripe before anal tubercle ( Fig. 7A, B ).

Epigyne as in Figs 7C–D , 8 . Epigynal plate weakly sclerotized, without depression. Median septum thin. Copulatory openings small, separated by median septum, located at centre of plate. Copulatory ducts thick, short. Connecting tubes thinner than copulatory ducts, inflated at middle parts. Bursa large, asymmetrical. Glandular appendages short, transverse.
