Distribution. Japan (The Ryukyus: Okinawa-jima Island, Kume-jima Is., Tokashikijima Is., Tokuno-shima Is.).

Notes. Both taxa (tokunoshimana and kimurai ) are conspecific (including structures of male genitalia and terminalia) after the study of the holotypes and addition material. MASUMOTO and AKITA (2001: 20) distinguished T. tokunoshimana from T. kimurai in the “smaller body, interocular space with a pair of impressions, narrower diatone (three times the width in T. kimurai ), and different ratios of the lengths of antennal and tarsal segments”. All these characters are variable in different populations. As a result a new synonymy is proposed.
