[1] It once occurred in the Las Vegas Valley, as well as Tule Springs, Clark County, southern Nevada in the United States, at elevations between 370 and 760 m (1,210 and 2,490 ft).

[8][9] The Vegas Valley leopard frog was considered extinct[6] after extensive searches have failed to locate the species.

[1] In 2011, a genetic analysis using DNA from preserved museum specimens of the Vegas Valley leopard frog revealed it is 100% identical genetically to the northwestern Mogollon Rim populations[10] of the Chiricahua leopard frog (Lithobates chiricahuensis), which is extant but threatened.

[10] L. chiricahuensis may remain a valid taxon for the southern and eastern range of the Chiricahua leopard frog.

The status of the Chiricahua leopard frog in northern Mexico may be uncertain, and this may be yet another separate lineage.
