Midas’ Glassfrog, Rana de Cristal Midas
© 2013 Frank Azorsa (1 of 7)
Teratohyla midas looks similar to Rulyrana flavopunctata, but it is differentiated from R. flavopunctata by a truncate instead of rounded snout, and by having less webbing on its hands and feet. It also looks similar to Nymphargus siren, but it is differentiated from N. siren by having a less prominent tympanum that points towards the sides and the back instead of towards the sides and the posterior, and it has more webbing on its hands and feet (Lynch and Duellman 1973).
In life, the entire backside is dark green with some gold fleck colorations on its sides, and has a white chest. The lining of the abdominal cavity is unpigmented, and it has green bones. The iris is silvery bronze with a black-netted pattern, and the hands and feet are a pale yellow-green color. In preservative, its entire backside is lavender with some white fleck colorations on its body. The rest of its body is creamy white (Lynch and Duellman 1973).
There is no information available on variation within the species.

Mitochondrial analyses suggest that Teratohyla is sister to Rulyrana, whereas nuclear analyses suggest that Teratohyla is sister to a clade formed by Chimerella, Espadarana, Cochranella, Rulyrana, and Sachatamia (Guayasamin et al. 2009).
The species name midas refers to a king in Greek mythology, who turned everything he touched into gold. This is a reference to the frog being found in Rio Aguarico, where gold has been found, and also a reference to the gold fleck coloration found on the frog (Lynch and Duellman 1973).
