Comment

In the Rana tarahumarae group (= Rana pustulosa group) according to the original publication, formerly confused with Rana pustulosa. Ahumada-Carrillo, Vázquez-Huizar, Vázquez-Diaz, and García-Vázquez, 2011, Herpetol. Rev., 42: 397, provided a record for southern Zacatecas, Mexico, and discussed the range. Rodríguez-Canseco, Ayón-Escobedo, and González-Estupiñán, 2013, Herpetol. Rev., 44: 622, reported sympatry of this species with Lithobates spectabilis, Lithobates neovolcanicus, and Lithobates forreri. Bañuelos-Alamillo, Quintero-Díaz, and Carbajal-Márquez, 2018, Mesoam. Herpetol., 5: 173, provided a record from the Municipio de Valparaiso, Zacatecas, Mexico. Loc-Barragán, Smith, Woolrich-Piña, and Lemos-Espinal, 2024, Herpetozoa, Wien, 37: 30, reported on the distributional and conservation status in the state of Nayarit, Mexico.
