Hamataliwa sanmenensis Song & Zheng 1992: 30 , figs. 1–4 (female holotype, 1 male allotype and 1 male paratype from Sanmen, Zhejiang Province, China, N 29°6’, E 121°18’, IZB, examined). — Song, Zhu & Chen 1999: 399, figs. 233E–H.

Diagnosis. This species resembles Hamataliwa tricuspidata F. O. Pickard­Cambridge, 1902 ( Brady, 1970: 100, figs. 50–53, 104–106, 128–129) in female epigynum with a large posterior depression and in the shape of median apophysis of male palpal bulb, but it can be easily distinguished from the latter by spermathecae of female epigynum small and oval ( Fig. 18); conductor of male palpal bulb with two distal processes, the upper one larger and triangular in shape, the lower one small with its tip round and hooked; retrolateral tibial apophysis large and flat, hatchet­like ( Figs. 19–20).
