In this paper we record a species of the Inella group for the first time in the Pliocene Mediterranean with the description of Inella bentae spec. nov. from the Estepona Basin, and Inella spec. and Triphora (s. l.) freixiensis spec. nov. from the Mondego Basin.
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.
The Naturalis Biodiversity Center (NBC) holds type specimens of 24 taxa of worldwide Triphoridae. For historical specimens (pre-World War II) the species name in its original combination is provided, followed by bibliographic details of the original description, the location of the known type material, the original description, a diagnosis, nomenclatural notes and illustrations of the type specimens and original labels. For more recently described species information is provided on the type locality and type material. The name Triphora raoulensis is an unpublished manuscript name by T. Iredale, “co-type” specimens are deposited in the NBC and National Museum of Wales (NMW), and the name is considered unavailable.
