A new crambid, Sufetula anania, sp. n., is described from Costa Rica. We describe and illustrate the eggs, larvae, pupae, and adults. This is the first report of Bromeliaceae as a host for Crambidae, specifically in the roots of pineapple (Ananas comosus (Linnaeus)), although the larvae also were found on surrounding weeds. The general morphology and biology of the new species are compared to those of Sufetula sacchari (Seín), the sugarcane root caterpillar, a pest of sugarcane in Puerto Rico and surrounding islands.
