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