Chiricahua Leopard Frog
|Taxonomic Notes: In 2011 Hekkala, Saumure, Jaeger, Herrmann, Sredl, Bradford, Drabeck and Blum, in an open access article published in Conservation Genetics (DOI 10.1007/s10592-011-0229-6), showed that Rana chiricahuensis, as treated in the following species account, includes two genetically distinct lineages. They were successful in obtaining sufficient genetic information from specimens of R. fisheri preserved in 1913 in ethanol and stored at the California Academy of Sciences to determine that it is a member of one of the two lineages, which is extant along the Mogollon Rim and White Mtns of central and eastern Arizona and extreme west-central New Mexico. Rana fisheri has long been considered to be extinct, but with this discovery the range of R. fisheri is extended from southern Nevada to central and eastern Arizona and adjacent New Mexico. R. chiricahuensis is accordingly restricted to the more southern and eastern portions of its former range. This species was placed in the genus Lithobates by Frost et al. (2006). However, Yuan et al. (2016, Systematic Biology, doi: 10.1093/sysbio/syw055) showed that this action created problems of paraphyly in other genera. Yuan et al. (2016) recognized subgenera within Rana for the major traditional species groups, with Lithobates used as the subgenus for the Rana palmipes group. AmphibiaWeb recommends the optional use of these subgenera to refer to these major species groups, with names written as Rana (Aquarana) catesbeiana, for example.|
