Urolophus tumbesensis, n. sp. is described and compared with the five other species of Urolophus from the Western Hemisphere. The new species is distinguished by color pattern of the dorsal surface, by several proportional measurements and by possessing denticles and thorns on the dorsal disc and tail in large adolescent and probably in adult specimens.
