See text Temnodiscinae Horný, 1963 Tropidodiscidae is an extinct family of Paleozoic fossil molluscs with isostrophically coiled shells.

They are of uncertain position taxonomically, in other words it is not known whether they were (Gastropoda (snails) or Monoplacophora)s.

This family has no subfamilies.
