Family: Pelobatidae
  (Archaic Toads)

 The family Pelobatidae is a fairly primitive family (as the name implies). Primitive features include a distinctive skeletal morphology, inguinal amplexus and vertical pupils (Nussbaum et al. 1983). The species in this family can be distinguished from true toads by the presence of teeth in the upper jaw. The single species found here in Idaho is the Great Basin Spadefoot Toad, Scaphiopus intermontanus ( = Spea intermontana).
