Collecting ducts that do not communicate along the length of the Wolffian ducts adjacent to the pelvic kidneys (character 1, state 1) evolved either once on the branch leading to all salamanders, excluding the Sirenidae (with secondary loss in the Proteidae; character 1, state 0), or evolved independently on the branches leading to the Cryptobranchidae + Hynobiidae and the Salamandroidea excluding the Proteidae.
The presence of anterior ventral glands (character 10, state 1) may represent a non-ambiguous synapomorphy for all salamanders to the exclusion of the Sirenidae, while the presence of posterior ventral glands (character 11, state 1) was recovered as the ancestral state for the Salamandroidea with a subsequent loss (character 11, state 0) on the branch leading to the Amphiumidae.
