A Bidder's duct is lost on the branch leading to the Amphiumidae + Plethodontidae + Rhyacotritonidae.
The presence of Kingsbury's (character 12, state 1) and dorsal pelvic (character 13, state 1) glands may represent a non-ambiguous synapomorphy for the Salamandroidea, whereas the presence of lateral pelvic glands (character 14, state 1) evolved on the branch leading to the Salamandroidea, with subsequent independent losses in the Amphiumidae and Salamandridae.
Non-anastomizing collecting ducts (character 2, state 0) were recovered as the ancestral state for salamanders, and collecting ducts that do anastomose (character 2, state 1) may have evolved independently on the branches leading to the Ambystomatidae + Dicamptodontidae + Salamandridae and Amphiumidae + Plethodontidae clades.
