Vegas Valley Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 107; Crother, Boundy, Campbell, de Queiroz, Frost, Highton, Iverson, Meylan, Reeder, Seidel, Sites, Taggart, Tilley, and Wake, 2001 "2000", Herpetol. Circ., 29: 14).


Extinct at the type locality (Las Vegas, Clark County, Nevada, USA), but populations along the Mogollon Rim in Arizona to west-southwestern New Mexico persist.


Confused with Rana onca in recent literature until sorted by Jaeger, Riddle, Jennings, and Bradford, 2001, Copeia, 2001: 339–351. Extinct since the 1940's in the Las Vegas area (see Honegger, 1981, Biol. Conserv., 19: 142). See Platz, 1984, Status report for Rana onca Cope, U.S. Fish Wildlife Serv.. Included in the Rana (Pantherana) berlandieri group by Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 331 (although the holotype is clearly a member of the Rana montezumae group—DRF, personal observation). Hillis and Wilcox, 2005, Mol. Phylogenet. Evol., 34: 308, suggested that extant populations of Lithobates chiricahuensis from Mogollon Rim region of central Arizona were likely referable to Lithobates fisheri. See map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 139, who regarded the species as extinct. Hekkala, Saumure, Jaeger, Herrmann, Sredl, Bradford, Drabeck, and Blum, 2011, Conserv. Genetics, 12: 1379–1385, provided genetic evidence that the populations found in central Arizona to western New Mexico were attributable to this species. Jennings, 2005, in Lannoo (ed.), Amph. Declines: 554–555, provided a detailed account of Rana fisheri in the sense of only referring to the Vegas Valley population, which is now extinct.  Dodd, 2013, Frogs U.S. and Canada, 2 : 547–551, provided an account that summarized relevant literature.
