The torrent salamanders or Cascade salamanders are a family (Rhyacotritonidae) with only one genus (Rhyacotriton) of salamanders. Originally the genus Rhyacotriton was placed in the family Ambystomatidae, later in the family Dicamptodontidae, and finally in 1992 it was placed into a family of its own. At the same time the only species Rhyacotriton olympicus was split into four species due to genetic analysis. The torrent salamanders are limited to the western USA, namely the states California, Oregon, and Washington.
The genus is divided into four species
- 瀑布急流螈 (Rhyacotriton cascadae)
- 哥伦比亚急流螈 (Rhyacotriton kezeri)
- 奥林匹亚急流螈 (Rhyacotriton olympicus)
- 南部急流螈 (Rhyacotriton variegatus)
