In our opinion this is unjustified. The genus Paracomitas is characterized and differentiated from Leucosyrinx and Comitas by a protoconch of 2.5 sharply carinated whorls. The protoconch is missing in the holotype of S. undosa, the only known specimen of the species. Therefore, pending additional data, we consider it a species of Leucosyrinx.
