Comment

Recognized as a distinct species by Collins, 1991, Herpetol. Rev., 22: 43, because of its allopatry and consistent diagnosability from Pseudotriton montanus. See comments under Pseudotriton montanusRaffaëlli, 2013, Urodeles du Monde, 2nd ed.: 232, provided a brief account, photograph, and map. Highton, Bonett, and Jockusch, 2017, in Crother (ed.), Herpetol. Circ., 43: 33, retained the allopatric and diagnosable Pseudotriton diastictus as a subspecies of Pseudotriton montanus on the basis of lack of information on "genetic differentiation", suggesting these authors are applying an arbitrary measure of sequence divergence as a species criterion.
