Savage and Kubicki, 2010, Zootaxa, 2719: 22, regarded the assignment of this species to Ecnomiohyla as problematic as it lacks the morphological synapmorphies they associate with application of the generic name. Garza-Tobón and Lemos-Espinal: 103, provided the first record for Coahuila at 20 km E of San Antonio de las Alanzas. Lemos-Espinal and Dixon, 2013, Amphibians and Reptiles of San Luis Potosí: 51–52, provided an account for San Luis Potosí, Mexico Köhler, 2011, Amph. Cent. Am.: 222–226, provided a brief summary of natural history for the species of Ecnomiohyla in Central America and provided a range map and photograph for this species. Lemos-Espinal and Smith, 2015, Check List, 11(1642): 1–11, noted the occurrence of the species in Hidalgo, Mexico, without providing a specific locality. Lemos-Espinal and Dixon, 2016, Amph.
