Milky tree frog
The milky tree frog lives in Mexico, Central America, Ecuador, and Venezuela.  It might be one species of frog or it might be many.  The Amphibian Species of the World uses the scientific name Trachycephalus "vermiculatus," with quotes, for all frogs that scientists thought were part of Trachycephalus typhonius but later decided weren't.  Other English names for these frogs include veined tree frog, common tree frog, warty tree frog, marbled tree frog, vein-eyed glue frog, Amazon tree frog, and pepper tree frog.
