Cyprinodon longidorsalis, the cachorrito de charco palmal or La Palma pupfish, is a species of fish in the family Cyprinodontidae. It was endemic to the Ojo de Agua la Presa in southwestern Nuevo Leon state in Mexico, but became extinct in the wild in 1994 due to habitat loss (now survives only in captivity). The same freshwater spring system was the home of three other pupfish: Cyprinodon ceciliae (extinct), Cyprinodon inmemoriam (extinct) and Cyprinodon veronicae (extinct in the wild, survives in captivity).
