6 species (see text) Rulyrana is a small genus of glass frogs.
[2] The generic name Rulyrana honors Pedro Ruiz-Carranza [fr] and John D. Lynch who have "contributed enormously to the understanding of centrolenid diversity, biology, and evolution".
In addition, "Ruly" is the nickname of Martín Bustamante, who has also contributed to amphibian conservation.
Internal features include green bones (in live specimens), lobed liver that is covered by a transparent hepatic peritoneum, whereas the ventral parietal peritoneum is white in its anterior part and transparent in its poster part.
The two genera, however, have largely disjunct distribution areas (Rulyrana are found in the Amazon Basin and the Colombian Cordillera Central while Sachatamia are not found further east than the Colombian Cordillera Central).
