Type locality: Not assigned. Distribution: Regions 2, 3. Name Elachistocleis ovalis historically applied to populations from Panama , Brazil , Colombia , Venezuela , Ecuador , Peru , and Bolivia . In Venezuela , present north of the Orinoco in open lowlands. Remarks: Name Elachistocleis ovalis long-applied to the Elachistocleis with a uniform yellow or orange ventral pattern in northern Venezuela . Caramaschi (2010) considered this name a nomen dubium (name of unknown or doubtful application), and species inquirenda (species of doubtful identity needing further investigation). Current authors agree that a complex of species is hidden under that name, and even knowing that the nomen ovalis is not valid, but must be used while awaiting a definitive solution and new available names for this long-standing taxonomic conundrum.
