A new araneid species Zygiella hiramatsui n. sp. is described using specimens obtained from Amami-ôshima Island, Japan. This species can be distinguished from allied Z. dispar by the much wider median area of the epigyne, or an unnamed apophysis neighboring the embolus that is short and truncated and a horn shaped apophysis of the tegulum in the male palp. It is uncommon for Zygiella spiders to inhabit subtropical regions, but this is the case for Z. hiramatsui n. sp. So it might be introduced previously into Amami-ôshima Is. from unknown habitat.
