Current SSAR Comments:
See comments under A. montanus. Nielson et al. (2006, Herpetologica 62: 235–258), using data from allozymes and mtDNA, reported evidence supporting recognition of two evolutionarily significant units represented by populations in the Olympic Mountains and populations south of the Umpqua River.
