Comment

Placed in the Hyla pinorum group and elevated from subspecies status under Hyla melanomma by Campbell and Duellman, 2000, Sci. Pap. Nat. Hist. Mus. Univ. Kansas, 16: 8, where it had been placed by Duellman, 1966, Univ. Kansas Publ. Mus. Nat. Hist., 17: 272. See account (as Hyla melanomma bivocata) by Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 402-403. In the Hyla miotympanum group of Duellman, 2001, Hylid Frogs Middle Am., Ed. 2: 915-917, who provided an account. In Exerodonta, but unnassigned to species group by Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 101. Köhler, 2011, Amph. Cent. Am.: 227–229, provided a brief summary of natural history for the species of Exerodonta in Central America and provided a range map and photograph for this species. Ríos-Rodas, Zenteno-Ruiz, Barragán-Vazquez, Canseco-Márquez, and López Luna, 2019, Check List, 15: 1161–1166, provided a record for extreme southwestern Tabasco, Mexico, near the borders of Veracruz and Chiapas.
