The family Abyssochrysidae was previously placed in the "Zygopleuroid group" (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

In 2008, the sister group Provannidae was moved into the superfamily Abyssochrysoidea Tomlin, 1927 by Kain et al. and the family Abyssochrysidae was also moved into the superfamily Abyssochrysoidea.^[1]
