Amphibia    Anura    Scaphiopodidae  

Western Spadefoot
Spea hammondii (Baird, 1859 “1857”)

Current SSAR Comments:
There is considerable inconsistency in the older literature regarding this taxon and both S. multiplicata and S. intermontana. Recent genetic evidence suggests two allopatric clades (Northern and Southern) may warrant recognition of an undescribed species (Neal et al., 2018, Conservation Genetics 19: 937–946).
