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) and Huber (1993).
1999 taxonomy Genera within the family Amathinidae according to the taxonomy of Schander, Van Aartsen & Corgan (1999) include: Genus Amathina J. E. Gray, 1842 Genus Amathinoides Sacco, 1896 Genus Carinorbis Conrad, 1862 Genus Cyclothyca Stearns, 1861 Genus Faluniella Cossman, 1921 Genus Iselica Dall, 1918 Genus Leucotina A.

2005 taxonomy This family has no subfamilies.
Genera This family presently comprises less than 100 recent and fossil species divided into seven genera: Amathina, Amathinoides, Carinorbis, Cyclothyca, Iselica, Leucotina and Phasianema.
Two additional genera, Faluniella and Plicifer may also be a part of Amathinidae: Faluniella Cossmann, 1921

Anatomy The shells are usually flat without coiling. They usually have strong axial ribs. Ponder described giant neurons in the cerebral ganglion.
