A new species of sea catfish (family Ariidae) from the tropical eastern Pacific, Arius cookie n. sp., is described. It can be easily separated from other western American ariid species by its elongated supraoccipital process, which is 1.5 to 1.7 times longer than the width of its base (in specimens over 343 mm SL). The species is known from fresh and brackish waters from Costa Rica to Colombia.
