Clavelinidae

Clavelinidae is a family of tunicates in the order Aplousobranchia.

Genera
, WoRMS recognizes the following genera in the family Clavelinidae:
 * Clavelina Savigny, 1816
 * Euclavella Kott, 1990
 * Nephtheis Gould, 1856
 * Pycnoclavella Garstang, 1891

Phylogeny
Pycnoclavella has occasionally been placed in a separate family, Pycnoclavellidae, although phylogenetic studies have recovered it as a relative of Clavelina. In multiple analyses, the monotypic genus Nephtheis appears to branch from within Clavelina.
