Microhedylidae are a taxonomic family of sea slugs, marine gastropod mollusks within the clade Acochlidiacea.
2005 taxonomy
Microhedylidae has been listed as a synonym of Parhedylidae in the taxonomy of Bouchet & Rocroi (2005).[2] Ganitidae Rankin, 1979 has been listed as a sole family within Hedylopsoidea.[2] The type genus of Livorniellidae was Livorniella Rankin, 1979.[2]
2010 taxonomy
Sensu Schrödl & Neusser (2010)[1] is Microhedylidae within the clade Microhedylacea.[1] Parhedylidae is a synonym of Microhedylidae.[1] Microhedylidae s.l. may informally include Ganitidae, but inclusion of Ganitidae within Microhedylidae requires further research and higher statistical support.[1]
