  Rhyacotritonidae
Relationships among the four recognized species of the family Rhyacotritonidae are based upon the allozymic study of Good et al.
The morphological characters given below are the ones standardly used to diagnose the salamander family Rhyacotritonidae and to assess its phylogenetic relationships to other salamanders.
The family Rhyacotritonidae was recognized by Good and Wake (1992) as containing the single genus Rhyacotriton.

Living salamanders are divided taxonomically into ten taxonomic families based upon phylogeny and anatomical features: Ambystomatidae (mole salamanders), Amphiumidae (amphiumas), Cryptobranchidae (hellbenders), Dicamptodontidae (Pacific giant salamanders), Hynobiidae, Plethodontidae (lungless salamanders), Proteidae (mudpuppies), Rhyacotritonidae (torrent salamanders), Salamandridae (true salamanders and newts) and Sirenidae (sirens).
These families are grouped into four taxonomic suborders as follows: Cryptobranchoidea (Cryptobranchidae, Hynobiidae), Karauroidea (Karauridae), Salamandroidea (Ambystomatidae, Amphiumidae, Batrachosauroididae, Dicamptodontidae, Plethodontidae, Prosirenidae, Proteidae, Rhyacotritonidae, Salamandridae, Scapherpetontidae) and Sirenoidea (Sirenidae).
(2005) phylogeny include: 1) Rhyacotritonidae as the sister taxon of Amphiumidae, Plethodontidae; 2) monophyly of Proteidae (i.

Class: Amphibia > Order: Caudata > Family: Rhyacotritonidae
Biol., 54, considered, on the basis of their parsimony analysis, that Rhyacotritonidae is the sister-taxon of Amphiumidae + Plethodontidae.
Biol., 54: 91-100, placed Rhyacotritonidae as the sister taxon of Amphiumidae + Plethodontidae, a conclusion also reached by Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull.
