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:

  • Genus Amathina J. E. Gray, 1842
  • Genus Sacco, 1896
  • Genus Conrad, 1862

2005 taxonomy[]

This family has no subfamilies.[4]

Genera[]

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

Two additional genera, and may also be a part of Amathinidae:[citation needed]

  • Cossmann, 1921


Genera within the family Amathinidae include:

Genera brought into synonymy
  • Adelactaeon Cossmann, 1895: synonym of Leucotina A. Adams, 1860
  • Amathinoides Sacco, 1896 † accepted as Clathrella Récluz, 1864 accepted as Conrad, 1862
  • Clathrella Récluz, 1864 accepted as Conrad, 1862
  • Isapis H. Adams & A. Adams, 1854 accepted as Iselica Dall, 1918 (Invalid: junior homonym of Isapis Doubleday, 1847 [Lepidoptera]; Iselica is a replacement name)
  • Myonia A. Adams, 1860: synonym of Leucotina A. Adams, 1860

Anatomy[]

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