Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA SCAPHIOPODIDAE

Scientific Name: Spea intermontana
Species Authority: (Cope, 1883)
Common Name(s):
English Great Basin Spadefoot
Synonym(s):
Scaphiopus intermontanus Cope, 1883
Taxonomic Notes: Garcia-Paris et al. (2003) used mtDNA to examine the phylogentic relationships of Pelobatoidea and found that the family Pelobatidae, as previously defined, is not monophyletic (Pelobates is sister to Megophryidae, not to Spea/Scaphiopus). They separated the Pelobatidae into two families: Eurasian spadefoot toads (Pelobates), which retain the name Pelobatidae; and North American spadefoot toads (Scaphiopus, Spea), which make up the revived family Scaphiopodidae.
