The southeastern Pacific chimaeroid Hydrolagus macrophthalmus De Buen, 1959, is reported for the first time in the northeastern Pacific on the basis of 1 male specimen (945 mm TL) caught on 13 April 1995 off Manzanillo, Colima (Mexico: 18° 30'N, 104° 15'W) at the surface above deep water (2 000 m). The first occurrence of this species increases the number of chimaeroid species known in the northeastern Pacific and expands their known range.Se registra por primera vez la presencia de la quimera Hydrolagus macrophthalmus De Buen, 1959, en aguas del Pacífico nororiental; especie cuya distribución se consideraba como exclusiva del Pacífico sur oriental. El 13 de abril de 1995, se recolectó 1 ejemplar macho (945 mm TL) en la superficie del mar frente a Manzanillo, Colima (México: 18° 30'N, 104° 15'O), en una zona de gran profundidad (2 000 m).
