Abstract

The Triphoridae (Gastropoda: Caenogastropoda: Triphoroidea) of the islands of Saint Helena and Ascension have not been thoroughly studied since the first records of this family were made by Edgar Albert Smith in 1890. Since then only five species of Triphora have been known from Saint Helena and since 1975 only a single species from Ascension Island. In this paper we identify three new species records for Saint Helena (Metaxia elizabethclinghamae spec. nov., Nanaphora renevanwalleghemi spec. nov. and Inella spec.) and four for Ascension Island (Cosmotriphora arnoldoi (Faber & Moolenbeek, 1991), Inella recta (E.A. Smith, 1890), Triphora albanoi spec. nov. and Triphora s.l. spec.). Three of the newly recorded species are described as new species.

Abstract

This paper reviews the Rissoinidae and Zebinidae collected during the Rumphius Biohistorical Expedition to Ambon, in 1990, with additional material collected by the second author (HLS). In all, 30 species belonging to the family Rissoinidae and 12 species belonging to the family Zebinidae are recognised. The wellknown species are listed with a short synonymy and the poorly known species are redescribed in detail and illustrated. The biogeographical relationships of the rissoinid and zebinid fauna from Ambon are briefly discussed.
