Diagnosis: The species is similar to A. labyrinthica ( Figs. 1–6 View FIGURES 1–6 ), but can be distinguished from the latter by the wide and saddle­like patellar apophysis, the acute tip of embolus, the absence of conductor median apophysis of male palp; the relatively small epigynal atrium, interiorly originated spermathecal heads, and the different positions of the spermathecal apophyses in females.

Redescription: Male palp ( Figs. 37–39 View FIGURES 31–39 ), with a saddle­like patellar apophysis and two tibial apophyses. Tip of embolus acute. Conductor median apophysis absent. Median apophysis membranous.

Epigynum ( Figs. 32–36 View FIGURES 31–39 ), with a conspicuous atrium. Copulatory openings invisible. Copulatory ducts saccate. Spermathecal heads near the midline. Spermathecal stalks distinct. Spermathecal apophyses small. Fertilization ducts arising posteriorly from the junctions of spermathecal stalks and bases.

For further details see Bösenberg & Strand (1906).

Distribution: China (Helongjiang, Jilin, Henan, Hubei, Hunan, Guizhou, Sichuan, Chongqin, Guangxi, Fujian); Russia; Korea; Japan.

Remarks: Topotypes of A. silvatica were collected and examined by Marusik & Koponen (2000) and they synonymized it with A. limbata . Judged by the figures of Oliger (1983), we consider their decision was correct. And, after collecting and examining some topotypes of A. daoxianensis , we think that A. daoxianensis should be treated as a junior synonym of A. silvatica .

The epigynal atria of this species are variable in different specimens. This leads easily to misidentifications.
