Antarctospira is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae.[1]
Taxonomy
The antarctic-subantarctic genus Antarctospira shares the axial sculpture pattern as well as the shape and position of the anal sinus with Leucosyrinx. Notably, four out of the five species attributed to Antarctospira were initially classified as Leucosyrinx
The examination of the radula revealed that Antarctospira possesses a radula with hypodermic marginal teeth thus suggesting its placement within the family Borsoniidae Bellardi, 1875. Furthermore, all species of Antarctospira have a much shorter and broader siphonal canal, which is barely separable from high and broad aperture. Its paucispiral protoconch is larger, attaining 2.5 mm in diameter (versus 1 mm in Leucosyrinx).[2]
