A note on the genus Rubritrochus (Gastropoda, Vetigastropoda, Trochidae), with descriptions of five new species

Previously, confusion about the species of the genus Rubritrochus Beck, 1995 resulted in erroneous species concepts and distributional patterns for the two identified species, R. declivis (Forsskål in Niebuhr, 1775) & R. pulcherrima (A. Adams, 1855). Instead, a total of eight Recent species is recognized in this paper. Five of these are newly described: R. moolenbeeki spec. nov. from the southern Red Sea to the Persian Gulf, R. ellenae spec. nov. from near Rodrigues Island, R. andamanensis spec. nov. from the Andaman Islands, R. lagerweijae spec. nov. from Sri Lanka, and R. simoni spec. nov. from western Thailand, Phuket area.
