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

Two shells of Iselica ovoidea

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).[2]

1999 taxonomy

Genera within the family Amathinidae according to the taxonomy of Schander, Van Aartsen & Corgan (1999)[3] include:

2005 taxonomy

This family has no subfamilies.[4]

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:

Genera within the family Amathinidae include:

Genera brought into synonymy

Anatomy

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