Amathinidae, is a taxonomic family mostly consisting of small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs in the superfamily Pyramidelloidea.

Together with Pyramidellidae, Ebalidae, Turbonillidae, Odostomidae and other genera they form the superfamily Pyramidelloidea.

Little is known on the biology of the group, but some data on the anatomy and systematic position is given by Ponder (1987)[1] and Huber (1993).

[4] This family presently comprises less than 100[citation needed] recent and fossil species divided into seven genera: Amathina, Amathinoides, Carinorbis, Cyclothyca, Iselica, Leucotina and Phasianema.

[citation needed] Two additional genera, Faluniella and Plicifer may also be a part of Amathinidae:[citation needed] Genera within the family Amathinidae include: The shells are usually flat without coiling.
