Colour (Fig. 11 View Figure 11 e and f). As in male.

Diagnosis

Small Ctenidae (total length male 5.1, female 6.4). The species resembles A. maolan Zhu, Chen & Song, 1999 (see Zhu et al. 1999: figs 1-5; Yin et al. 2012: fig. 473a-e; Marusik and Omelko 2016: figs 1-13 and 32-34) by having similar distal retrolateral spine, tegular apophysis (Fig. 10 View Figure 10 a-c) and fertilisation ducts (Fig. 11 View Figure 11 b), but can be distinguished by the embolus arising at 6.30 o’clock position, its tip with membranous apophysis (Fig. 10 View Figure 10 b and Fig. 14 a; embolus arising centrally from tegulum, its tip without membranous apophysis in A. maolan ), by the median plate with a large n-shaped sclerite (Fig. 11 View Figure 11 a; absent in A. maolan ), by the lateral teeth pointing postero-medially (Fig. 11 View Figure 11 a; lateral teeth pointing medially in A. maolan ) and by the spermathecae nearly cylindrical (Fig. 11 View Figure 11 b; spermathecae nearly wavy in A. maolan ).

Etymology

The specific name refers to the type locality and is a noun in apposition.

Distribution
