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.

However, in terms of cloacal glands, the Rhyacotritonidae possess advanced features that seemingly unite this taxon with the Salamandroidea (Sever, 1991a), as also recovered when phylogenies have been reconstructed with a suite of molecular (mitochondrial and nuclear) and morphological character sets (Duellman and Trueb, 1986: Larson and Dimmick, 1993; Hay et al.
