| The Tumbalá Climbing Rat may prove to be a subspecies of Peters's Climbing Rat. If DNA studies determine that it is, in fact, a separate species, it will be considered critically endangered, because it is known to live only in a few isolated places in Chiapas, in southern Mexico. Presumably its lifestyle is similar to that of Tylomys nudicaudus.
