Comment

See Myers and Duellman, 1982, Am. Mus. Novit., 2752: 15, and Duellman, 2001, Hylid Frogs Middle Am., Ed. 2: 878–879, who provided an account and transferred the former Hyla lancasteri group into the Hyla pictipes group. See comment under Hyla calypsa with which this was formerly confused. Lips and Savage, 1996, Proc. Biol. Soc. Washington, 109: 17–26, included this species (as Hyla lancasteri) in a key to the tadpoles found in Costa Rica. See account by Savage, 2002, Amph. Rept. Costa Rica: 311–312. In the Isthmohyla pictipes group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 103. Köhler, 2011, Amph. Cent. Am.: 236–244, provided a brief summary of natural history for the species of Isthmohyla in Central America and provided a range map and photograph for this species. Faivovich, Pereyra, Luna, Hertz, Blotto, Vásquez-Almazán, McCranie, Sánchez, Baêta, Araujo-Vieira, Köhler, Kubicki, Campbell, Frost, Wheeler, and Haddad, 2018, S. Am. J. Herpetol., 13: 16, discussed the need for further taxonomic elucidation of this nominal species, which might contain at least one other lineage.
