Diagnosis.

The new species resembles A. zhishengi in having similar-shaped anterior part of atrium (cf. Fig. 3 B, C View Figure 3 , and fig. 29 A, B in Zhu et al. 2017), but can be differentiated from it by: 1) septum (Se) reaching posterior edge of epigyne (Fig. 3 B View Figure 3 ) (vs. epigyne with scape, fig. 29 A in Zhu et al. 2017), and 2) copulatory duct (CD) nearly straight (Fig. 3 C View Figure 3 ) (vs. strongly curved, fig. 29 B in Zhu et al. 2017).

Female. Total length 7.94. Carapace: 3.68 long, 2.91 wide. Abdomen: 4.70 long, 2.95 wide. Eye sizes and interdistances: AME 0.22, ALE 0.24, PME 0.20, PLE 0.21, AME – AME 0.07, AME – ALE 0.06, PME – PME 0.19, PME – PLE 0.12, ALE – PLE 0.07. MOA: anterior width 0.44, posterior width 0.55, 0.48 long. Clypeus 0.10 long. Chelicerae with 3 promarginal and 3 retromarginal teeth.

Copulatory opening (CO) located posteriorly. Copulatory ducts (CD) curved. Spermathecal head (SH) clavate. Spermathecae (S) fist-shaped, posteriorly located spaced by about 2 times diameter of spermathecae. Fertilization ducts (FD) extending antero-laterally.
