Common Names

Mexican Fringe-limbed Treefrog (Liner, 1994, Herpetol. Circ., 23: 22; Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 54; Liner and Casas-Andreu, 2008, Herpetol. Circ., 38: 19).

Cope’s Streamside Treefrog (Campbell, Brodie, Caviedes-Solis, Nieto-Montes de Oca, Luja-Molina, Flores-Villela, García-Vázquez, Sarker, and Wostl, 2018, Zootaxa, 4422: 369). 

Distribution

Both sides of the Continental Divide in Puebla, Veracruz, Oaxaca, and Guerrero, Mexico, in pine-oak forest at 1219–2900 m; along the Sierra Madre del Sur of Guerrero, almost the length of the state; doubtfully reported from Hidalgo (see comment); and from Morelos southern state of México west along the edge of the plateau in northern Michoacán and north through Nayarit to southeastern Sinaloa and southwestern Durango; encountered along rapidly flowing streams and rivers, where it often sits on large stream-side boulders or on vegetation or exposed tree roots; also found in undisturbed pine-oak forest far from flowing water. 

Geographic Occurrence

Natural Resident: Mexico

Endemic: Mexico

Comment

In the Plectrohyla bistincta group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 105. Campbell, Brodie, Caviedes-Solis, Nieto-Montes de Oca, Luja-Molina, Flores-Villela, García-Vázquez, Sarker, and Wostl, 2018, Zootaxa, 4422: 366–384, substantially revised the species so the following literature should be considered background. For account (as Hyla bistincta) see Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 457–462. López-Garduño and Rodríguez-Romera, 2012, Herpetol. Rev., 43: 298, provided a record for the Municipality of Valle de Bravo in the state of Mexico. 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 and this was doubted by Campbell, Brodie, Caviedes-Solis, Nieto-Montes de Oca, Luja-Molina, Flores-Villela, García-Vázquez, Sarker, and Wostl, 2018, Zootaxa, 4422: 366–384. Luja-Molina and Grünwald, 2015, Herpetol. Rev., 46: 223, provide for Municipality of Xalisco, Nayarit, Mexico, and commented on the range. Caviedes-Solis and Leaché, 2018, Biol. J. Linn. Soc., 123: 767–781, reported on diversification, noting four unnamed lineages within nominal Sarcohyla bistincta which did not form a monophyletic group. This paper was immediately followed by Zarza, Connors, Maley, Tsai, Heimes, Kaplan, and McCormack, 2018, PeerJ, 6(e6045): 1–25, also discussed cryptic lineages within nominal Sarcohyla bistinca: 1) Michoacan to the state of Mexico; 2) Morelos; 3) central and eastern Guerrero; 4) western Guerrero; 5) Puebla, Veracruz [including the type locality of Sarcohyla bistincta], and Oaxaca; 6) northern Guerrero; 7) Pacific slope of Guerrero (and the sister taxon of Sarcohyla pentheter), but also cautioned that additional sampling was required prior to naming species. Lemos-Espinal, Smith, and Valdes-Lares, 2019, Amph. Rept. Durango: 70–71, provided a brief account for Durango, Mexico. Lemos-Espinal and Dixon, 2016, Amph. Rept. Hidalgo: 376–377, provided a brief account and map for Hidalgo, Mexico.
