Oedipina
Oedipina is a genus of salamanders in the family Plethodontidae. They achieve respiration through the skin and the tissues lining the mouth. Species of Oedipina are native to Honduras, Colombia, Costa Rica, Ecuador, and Mexico. Their common name, worm salamanders, derives from the species' extraordinarily slender form with tiny limbs and digits. The genus was originally named Oedipus, but was renamed because the name Oedipus was already occupied.
