A new rhynchocinetid shrimp, Cinetorhynchus fasciatus, is described and illustrated from three male specimens collected from Chichi-jima Island of the Ogasawara Islands, Japan, and Oahu of the Hawaiian Islands. The new species closely resembles C. hiatti (Holthuis & Hayashi) and C. rigens (Gordon) in the armature of the ambulatory pereiopods, carpi and dactyli in particular, but may be distinguished by the combination of the fourth abdominal somite rounded on the posteroventral angle, the stylocerite not extending beyond the end of the antennular distal segment, the meri of the third and fourth pereiopods bearing two to four spines on the lateral surface, the second maxilliped bearing a developed podobranch, and the distinctive coloration. A modified key to species of the genus is proposed.
