Shallow water turrids of Ile des Pins, New Caledonia (Mollusca, Gastropoda)

Abstract

Abstract: The marine malacofauna of New Caledonia is among the most studied and best known of the Indo-Pacific region. Previous studies have shown that its richness and species compositions are examples of extreme spatial heterogeneity. Turrids are among the richest and most diverse groups of marine gastropods. In the present paper the shallow-water turrid fauna of Ile des Pins is inventoried for the first time. 174 morphotypes hosted in 8 families are herein recorded, of which 22 species are considered new records for New Caledonia. The following new combinations were introduced: Mitromorpha drivasi (Chang, 1995), Acrista nana (Hervier, 1896), Acrista latirella (Melvill & Standen, 1896), Acrista pusilla (Dunker, 1871), Acrista tuberculifera (Hervier, 1896), Hemilienardia idiomorpha (Hervier, 1897), Heterocithara diatula (Hervier, 1897), Heterocithara isophanes (Hervier, 1897), and Pseudorhaphitoma hervieri Hedley, 1922.
