Strict consensus tree of 420 most parsimonious trees (length = 635 steps) from our unconstrained analysis with all 40 taxa. Extinct taxa are in bold.
greatly reduced the number of most parsimonious trees (from 420 to 32), and provided better resolution for the Molgini, separating out the non-North American Molgini, Taricha, and
Notophthalmus. One major issue with the unconstrained analyses is that Notophthalmus viridescens and, when included, Notophthalmus crassus do not form a group with
