Five species, Pa. agelenae (Momoi, 1966) , Pa. fumeae Momoi, 1966 , Pa. saigusai Momoi, 1966 , Pa. sakabei Momoi, 1966 , and Pa. subtilis Momoi, 1966 , have been recorded from Japan . All species except for Pa. agelenae are relatively rarely collected in the field investigations. I recognize at least eight additional species from Japan . In this study, I newly describe five of them below. The identification of remaining undetermined species requires additional specimens. In addition, I record some distributional data of Pa. agelenae , Pa. fumeae , Pa. sakabei , and Pa. subtilis below. Japanese species including three undetermined species can be distinguished by the following key. Preliminary key to Japanese species of the genus Paraphylax ( ♀ ) 1. T II and T III covered with longitudinal striae except for smooth posterior area (e.g., Figs 21D , 22F ). ............................................................................................ 2 -.
