Distribution. W. Cape (Hermanus) to Namibia (Luderitz); living intertidal and shallow subtidal.

Notes. Following Kilburn & Rippey (1982: 41) Trochus roseus Gmelin, 1791 is best considered a nomen dubium. It was based on a figure (Chemnitz 1781: pl. 171, fig. 1675) which may represent either Gibbula cicer or G. multicolor .

Jujubinus Monterosato, 1884 . Type species (s.d. Pilsbry 1889): Trochus matonii Payraudeau, 1826 [= Trochus exasperatus Pennant, 1777].

As pointed out by Vilvens (2012), the genus level taxonomy of high-spired cantharidine taxa (tribe Cantharidini of Hickman & McLean, 1990) is far from clear. For the two following species I maintain the current generic referal, but with little confidence. It seems unlikely that Jujubinus, with a European type species, will prove to be appropriate for these species once molecular data become available. For the present, however, none of the other potentially applicable generic names stands out as being more suitable.
