  Dicamptodontidae
Relationships among the four extant species of the family Dicamptodontidae are based upon the allozymic study of Good (1989).
The family Dicamptodontidae is part of the salamander suborder Salamandroidea, which contains all of the internally fertilizing salamanders (Duellman and Trueb, 1986).
The family Rhyacotritonidae formerly was recognized as the subfamily Rhyacotritoninae of the family Dicamptodontidae, but was given family-level status by Good and Wake (1992) following evidence that the Dicamptodontidae as formerly recognized was not monophyletic (Larson, 1991; Larson and Dimmick, 1993).

 ADW: Dicamptodontidae: Information
The family was recently formed when the type genus, Dicamptodon, was removed from the Ambystomatidae.
Dicamptodontidae and Ambystomatidae are sister to each other.
Originally, the subfamily Rhyacotritoninae was placed within the Dicamptodontidae, but recent molecular work provides strong evidence that this maintains a paraphyletic group.

 Caudate Families (Newts & Salamanders)
The families Dicamptodontidae and Rhyacotritonidae have both been included in Ambystomatidae, but were removed based on genetic information.
Dicamptodontidae is a sister taxa to Ambystomatidae, while Rhyactotritonidae is more distant.
Dicamptodontidae is comprised of four species, in the single genus Dicamptodon.

 Amphibian Species of the World - Dicamptodontidae Tihen, 1958
Sci., 3: 1, proposed the Dicamptodontinae and Rhyacotritoninae as subfamilies of the Ambystomatidae; Edwards, 1976, J. Morphol., 148: 325, placed both subfamilies in the Dicamptodontidae, an arrangement accepted by Estes, 1981, Handb.
Sever, 1992, J. Morphol., 212: 305-322, provided evidence that Dicamptodon was the sister-taxon of the Ambystomatidae rather than to Rhyacotriton and suggested that they be placed in separate families, although he did not formally propose the name or diagnosis.
Zool., 126: 13, recognized the Rhyacotritonidae and argued on the basis of a phylogenetic analysis for the sister-group status of Dicamptodontidae and Ambystomatidae.

The evolutionary relationships and historical diversification of a group of organisms constitute essential knowledge for understanding the group's diversity, value as a natural resource and need for conservation.
Nine major groups of salamanders are currently recognized as taxonomic families (Ambystomatidae, Amphiumidae, Cryptobranchidae, Dicamptodontidae, Hynobiidae, Plethodontidae, Proteidae, Salamandridae and Sirenidae); earlier results of this project suggest that the Dicamptodontidae as currently recognized incorrectly groups two very different evolutionary lineages.
The evolutionary relationships of the salamander families to each other and the relationships of the major lineages contained within each family constitute the focus of this work.

New evidence may reveal that a group of species or genera that were once believed to be mem­bers of one family are actually more closely related to another group or are not related to the family with which they for­merly were associated.
For example, salamanders in the fam­ilies Dicamptodontidae and Rhyacotritonidae formerly were placed in the Ambystomatidae.
At the family level, the greatest diversity is in the Nearctic region, where all families (except Hynobiidae) occur, and five families (Ambystomatidae, Amphiumidae, Dicamptodontidae, Rhya­cotritonidae, and Sirenidae) are endemic.

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).
A few Mesozoic fossil salamanders (genera Comonecturoides, Galverpeton and Hylaeobatrachus, each containing a single species) have not been assigned to taxonomic families or suborders.
