New records of Caribbean Gastropods (Skeneidae, Tornidae, Orbitestellidae and Omalogyridae) for Saint Peter and Saint Paul Archipelago (Brazil)

The present study records the occurrence of gastropods belonging to the families Skeneidae Thiele 1929 (Lodderena ornata Olsson & Mc-Ginty 1958), Tornidae Sacco 1896 (Cyclostremiscus schrammii Fischer 1857), Orbitestellidae Iredale 1917 (Orbitestella bermudezi Aguayo & Borro 1946) and Omalogyridae Sars 1878 (Ammonicera circumcirra Rolan 1992, A. cf. familiaris Rolan 1992, A. lineofuscata Rolan 1992 and A. sculpturata Rolan 1992) for the Saint Peter and Saint Paul Archipelago (SPSPA, Brazil) and comments on dispersion possibilities based on the locations of greater incidence (Caribbean) of these species and the colonization of remote oceanic islands of the Atlantic. We believe that the taxa studied have a circum-Caribbean distribution and are dispersed from the Caribbean and northeastern portion of South America to the SPSPA under the influence of the equatorial subcurrent, occupying seamounts and/or oceanic banks in a gradient fashion.
