During the epidemiological investigations of scrub typhus in Japan, members of the investigative team collected many specimens of sucking lice from three Dsinezumi-Shrews (Crocidura dsinezumi chisai Thomas, 1906) trapped at three different places in Honshu , Japan. The species of louse belongs to the genus Polyplax and seems to be undescribed heretofore. In the present paper , description and drawing of this species will be given.
