2005 taxonomyEdit

Acochlidiidae was classified as the only family within the superfamily Acochlidioidea Küthe, 1935 in the taxonomy of Bouchet & Rocroi (2005).[4] Palliohedylidae was in turn classified as the only family within the superfamily Palliohedyloidea.[4]

2010 taxonomyEdit

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


According to Schrödl & Neusser (2010),[1] there are three genera in the family Acochlidiidae:[1]

Acochlidium Strubell, 1892[1][5]

Palliohedyle Rankin, 1979[1]

Strubellia Odhner, 1937[1]
