Twenty-three species of Acteonidae, Bullinidae and Ringiculidae are documented from the so-called "Cabarruyan" fauna from the Plio-Pleistocene of Pangasinan, the Philippines. There are eleven species of Acteonidae, one species of Bullinidae and eleven species of Ringiculidae. Seven species are described here as new, these are: Bathyacteon valdesi nov. spec., Bullina virgoides nov. spec., Ringic...

Recent studies on phylogenetic relationships within the molluscan class Gastropoda have involved morphological (Kay et al., 1998), ultrastructural (Healy, 1996), and molecular (e.g., Lydeard et al., 2002; McArthur and Koop, 1999) approaches. These investigations have provided new insights into gastropod affinities and classification and have enabled a vigorous testing of taxonomic schemes for t...

Baseline biodiversity data are key for ecological and evolutionary studies especially relevant areas such as the Maldivian Archipelago in Indian Ocean, which can act a stepping-stone transport of widely distributed marine species. We surveyed islands reefs Faafu Malé Atolls with snorkeling scuba diving, collecting two gastropod subclasses, Heterobranchia Vetigastropoda. Our inventory comprises ...
