The sides of the head have dark brown masking from the nose to the tympanum.

The sides of the frog's body are dark brown with irregular yellow spots.

Scientists named after the place where they saw the frog: La Esperanza in Sierra Juarez.

Possible causes include habitat loss, habitat fragmentation and the resulting reduced genetic diversity, disturbances from motor vehicle traffic, disease, general urbanization, and both climate change and the resulting increased UVB exposure.

[3] Residents near La Esperanza have conserved 4000 hectares of land to preserve habitat for this frog and other species.
