2005 taxonomy

edit

Microhedylidae has been listed as a synonym of Parhedylidae in the taxonomy of Bouchet & Rocroi (2005).[3] Ganitidae Rankin, 1979 has been listed as a sole family within Hedylopsoidea.[3] The type genus of Livorniellidae was Livorniella Rankin, 1979.[3]

2010 taxonomy

edit

Sensu Schrödl & Neusser (2010)[5] is Microhedylidae within the clade Microhedylacea.[5] Parhedylidae is a synonym of Microhedylidae.[5] Microhedylidae s.l. may informally include Ganitidae, but inclusion of Ganitidae within Microhedylidae requires further research and higher statistical support.[5]
