A new species of chirostylid squat lobster, Uroptychus tuerkayi sp. nov., is described based upon material collected by the French “Seamount 2” project (1993) from the Atlantis-Great Meteor Seamount Chain south of the Azores Islands, at a depth of 340-730 m. Uroptychus tuerkayi resembles U. maroccanus Türkay, 1976 from the Moroccan coast, but it can be readily distinguished by the eyes being distinctly longer instead of as long as broad (globular in U. maroccanus), the antennal article 5 with a small instead of prominent distomesial spine, the anterolateral spine of the carapace slightly smaller than or subequal to, instead of much smaller than the lateral orbital spine, the pterygostomian flap anteriorly acuminate and not strongly produced to a spine as in U. maroccanus, and in having pereopod 1 with obsolescent instead of distinct spines on the merus and carpus. This is the sixth species of Uroptychus from the eastern Atlantic. A key to the eastern Atlantic species of Uroptychus is provided.
