Sumario:A new species of Uristes Dana, 1849 (Uristidae) collected from shallow waters in the Beagle Channel, Argentina, is described and illustrated. Uristes yamana n. sp., the third species of this genus reported for the Magellan area, is closely related to U. serratus Schellenberg 1931, principally by the possession of an unusual stout gnathopod 1 propodus. Both species can be separated by telson shape and relative setosity of uropod 3. The geographical distribution of U. gigas Dana, 1849 is also emended.
