The bigfoot splayfoot salamander or big-footed salamander (Chiropterotriton magnipes) is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from northeastern Queretaro, at elevations of 1,300–1,810 m (4,270–5,940 ft) asl. Its natural habitats are caves and crevices in pine-oak forest. It has also been spotted in a tunnel under a church. It is threatened by habitat loss: removing the forest causes caves to dry up. The species has never been common, but searches in recent years has failed to locate it.
