摘要

Two salticid species, Irura yueluensis (Peng & Yin 1991) and Synageles hilarulus (C. L. Koch1846) are newly recorded from Japan. The genus Irura is also new to Japan, and I. yueluensis is the single Japanese species at the present. This genus can be distinguished from other salticid genera by having wide flatbody and male long fang.
