Microhedylidae s.l. (including Ganitidae):

Microhedylidae are a taxonomic family of sea slugs, marine gastropod mollusks within the clade Acochlidiacea.

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.

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.

Genera within the Microhedylidae include:

Microhedyle Hertling, 1930

Parhedyle Thiele, 1931

Pontohedyle Golikov & Starobogatov, 1972
