Diagnosis. This species is similar to Hamataliwa sanmenensis Song & Zheng, 1992 in copulatory ducts of female epigynum long and thin, spermathecae small and oval ( Fig. 23), but it differs from this species in having the depression of female epigynum as long as wide ( Fig. 22); tip of conductor of male palpal bulb sickle­like, distal end of ventral tibial apophysis not swollen, retrolateral tibial apophysis small and flat, not hatchet­like ( Figs. 24–25).
