| The puddle frog, Engystomops pustulosus (Cope, 1864) ranges from eastern and southern Mexico (Veracruz and Oaxaca) southward through Central America to Colombia and Venezuela. The photographs on this page were all taken in Trinidad. This species was long considered part of the genus Physalaemus. |
| The species in the Leiuperidae were previously placed in the family Leptodactylidae. Molecular evidence suggests that the 7 genera and 75 species belong in their own family. Puddle Frogs range from southern Mexico southward through Central and South America to Chile and Argentina. Grant, et al. (2006, Bulletin of the American Museum of Natural History, 299) have removed these frogs from the Leptodactylidae and consider them to be the sister taxon to Bufonidae + Hylodidae + Dendrobatoidea. |
