While distinct from most other glass frogs, there are no characters that could unambiguously place a species in Sachatamia or in the genus [[Rulyrana]]; genetic data are needed for an unambiguous allocation. The two genera, however, have disjunct distribution areas (Rulyrana are found in the [[Amazon Basin]] while Sachatamia are not found further east than the Colombian [[Cordillera Central (Colombia)|Cordillera Central]]).
