Amathinidae, is a taxonomic family of mostly small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs. It 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. Together with Pyramidellidae, Ebalidae, Turbonillidae, Odostomidae and otherb genera they are forming 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).
