Calma glaucoides (Alder & Hancock, 1854 )

by Enric Madrenas
Class: Gastropoda  Cuvier, 1797 
Subclass: Heterobranchia  J.E. Gray, 1840 
Clade: Euthyneura  Spengel, 1881 
Clade: Nudipleura  Wägele & Willan, 2000 
Order: Nudibranchia  Cuvier, 1817 
Suborder: Dexiarchia  Schrödl, Wägele & Willan, 2001 
Infraorder: Cladobranchia Willan & Morton, 1984
Parvorder: Aeolidida Odhner, 1934
Superfamily: Fionoidea  Gray, 1857 
Family: Fionidae  Gray, 1857
Genus: Calma  Alder & Hancock, 1855 
Species: Calma glaucoides (Alder & Hancock, 1854) [Eolis]

Taxonomic note: The phylogenetic analyses performed by Cella et al. (2016) revealed that the traditional Tergipedidae family is polyphyletic and belongs to a larger monophyletic clade including members of the traditional families Eubranchidae, Fionidae and Calmidae; this was an unexpected result, since the validity of these taxa and their distinctness from the Tergipedidae was never questioned before. They proposed to join the families Tergipedidae, Eubranchidae, Calmidae and Fionidae under the name of Fionidae.
