Pardosa multidontata Qu, Peng & Yin, 2010: 392, figs 5a–b, 11a–e (♂ ♀).
Diagnosis
This species resembles S. medogensis gen. et sp. nov. (Figs 1–3), but differs by having the distal end of the lateral projection of the median apophysis truncate, almost overlapping the lateral edge of the cymbium in this species (Figs 4A–B, 5C–F), whereas this end is blunt, slightly touching the lateral edge of the cymbium in ventral view in S. medogensis gen. et sp. nov. (Figs 1C–D, 2A–B, 3C–F). The septum longer than wide and the spermathecal heads are oval with thick spermathecal stalks in this species (Figs 4C–D, 5G–H), whereas the septum is wider than long and the spermathecal heads are spherical with fine spermathecal stalks in S. medogensis gen. et sp. nov. (Figs 2C–D, 3G–H)
