Remarks. The holotype was not found in the collection of NSMT, though the late Dr. Imadaté noted the type specimen was deposited there. Hence, the specimens examined were those identified by the late Dr. Imadaté as Ps. babai in Imadaté’s Proturan Collection in NSMT.

Distribution. Japan (Honshu, Shikoku, Kyushu, Iriomote and Yonaguni Islands).
