Comment

Subgenus Rana, Rana berlandieri subgroup of the Rana pipiens group as defined by Hillis, Frost, and Wright, 1983, Syst. Zool., 32: 132–143. In equivalent Rana (Pantherana) berlandieri group of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 331. Elevated from status as a subspecies of Rana berlandieri by Frost, 1982, Syst. Zool., 31: 57–67. Lips and Savage, 1996, Proc. Biol. Soc. Washington, 109: 17–26, included this species (as Rana forreri) in a key to the tadpoles found in Costa Rica. See accounts by Savage, 2002, Amph. Rept. Costa Rica: 399–400, and McCranie and Wilson, 2002, Amph. Honduras: 482–485, who noted a hybrid zone with "Rana berlandieri" (now Rana brownorum). Grismer, 2002, Amph. Rept. Baja California: 81–82, provided an account for the introduced Baja California, Mexico, population. Zaldívar-Riverón, León-Regagnon, and Nieto-Montes de Oca, 2004, Mol. Phylogenet. Evol., 30: 38–49, provided a molecular phylogenetic analysis of this species and near relatives, including several undescribed relatives: "Pagapayo" (central Guerrero), "Arcelia" (Balsas-Tepalcatepec valley) and "Colima" (southern Jalisco to central Oaxaca). Köhler, Veselý, and Greenbaum, 2005 "2006", Amph. Rept. El Salvador: 66–68, provided an account (as Rana forreri, and for El Salvador) and a color photograph. McCranie, 2007, Herpetol. Rev., 38: 38, summarized the departmental distribution in Honduras. Lemos-Espinal, 2007, Anf. Rept. Chihuahua Mexico: 58–59, provided an account for Chihuahua, Mexico. Köhler, 2011, Amph. Cent. Am.: 291–295, provided a brief summary of natural history and identification key for the species of Lithobates in Central America and provided a range map and photograph for this species. Valdéz-Villavicencio, Peralta-García, and Hollingsworth, 2015, Herpetol. Rev., 46: 379, provided a record in the Río Sonora drainage at the municipality of Hermosillo, Sonora, Mexico. Rendón Suárez, Mercado-Silva, Palomera García, and Iñiguez Dávalos, 2016, Southwest. Nat., 61: 241–273 provided records from the Marabasco Basin of the Jalisco–Colima border region. See comments by McCranie, Sunyer, and Martínez-Fonseca, 2019, Rev. Nicaraguense Biodiversidad, 52: 11, regarding systematics in Honduras. Ahumada-Carrillo, Grünwald, López Cuellar, and Jones, 2020, Herpetol. Rev., 51: 277–278, reported the species from the municipality of Villa de Guerrero, northern Jalisco, Mexico.
