Type material

Holotype INDONESIA • Flores Sea ; 7°24′ S, 118°15.2′ E; depth 794 m; NATURALIS, ZMA.MOLL.136841 .

Remarks

In general shell characters, including the position of the anal sinus, the species is referable to Leucosyrinx . Shuto (1970a) transferred it to Paracomitas Powell, 1942 . 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 .
