XAetomylaeus asperrimus (Gilbert, 1898).

Rough Eagle Ray. While there is one report from within our range, from Bahía Almejas, southern Baja California (Fitch 1953), it is highly likely this specimen was Aetobatus laticeps Gill, 1865. Aetomylaeus asperrimus is known from Costa Rica, Ecuador, and the Islas Galápagos (Kyne et al. 2020).
