Comment

Savage and Wake, 2001, Copeia, 2001: 52-64, substantially revised this species through the recognition of several former synonyms as distinct species. McCranie and Wilson, 2002, Amph. Honduras: 89-92, provided an account. McCranie, 2007, Herpetol. Rev., 38: 36, summarized the departmental distribution in Honduras. Köhler, 2011, Amph. Cent. Am.: 30–32, compared this species to others in Central America, provided maps, and photographs. Hernández-Ordóñez, Arroyo-Rodríguez, González-Hernández, Russildi, Luna-Reyes, Martínez-Ramos, and Reynoso-Rosales, 2015, Rev. Mexicana Biodiversidad, 86: 457–468, reported localities from the Lacondona Rainforest in Chiapas, Mexico.
