Remarks

The Antarctic-subAntarctic genus Antarctospira shares the axial sculpture pattern as well as the shape and position of the anal sinus with Leucosyrinx ( Kantor et al. 2016) . Notably, four out of the five species attributed to Antarctospira were initially classified as Leucosyrinx : Antarctospira badenpowelli (Dell, 1990) (type species), A. mawsoni (Powell, 1958) , A. paragenota (Powell, 1951) , A. falklandica (Powell, 1951) . However, 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 (vs ca 1 mm in Leucosyrinx ).
