The nematode Ascarophis ayalai Caballero, 1975, originally inadequately described from Arius liropus (Bristol in Gilbert, 1897) in Nayarit and Sonora, Mexico, is redescribed on the basis of examination of types and new material obtained from the stomach of the Mayan sea catfish Ariopsis assimilis (Günther, 1864) from the Bay of Chetumal, Quintana Roo, Mexico. Ascarophis ayalai differs markedly from its congeners in possessing a left spicule of unusual shape and structure. Ariopsis assimilis represents a new host record for A. ayalai.
