Acochlidiidae are a taxonomic family of shell-less freshwater gastropods (one of them Palliohedyle weberi lives in brackish water),^[1] aquatic gastropod mollusks within the clade Acochlidiacea.

2005 taxonomy

Acochlidiidae was classified as the only family within the superfamily Acochlidioidea Küthe, 1935 in the taxonomy of Bouchet & Rocroi (2005). Palliohedylidae was in turn classified as the only family within the superfamily Palliohedyloidea.

2010 taxonomy

Schrödl & Neusser (2010) redefined the taxonomy of Acochlidiacea in 2010, placing the family Acochlidiidae in the clade Hedylopsacea.^[1]
