THE GENUS TROPHON MONFORT, 1810 (GASTROPODA: MURICIDAE) IN THE TERTIARY OF PATAGONIA

Abstract

Species of Trophon Montfort, 1810 are well known from Tertiary rocks exposed over a wide area of Patagonia. All nominal species referable to the genus were revised and, where necessary, synonymized. Valid species were redescribed and reillustrated, based on type material and additional material collected at other localities ranging from Península Valdés to south of the mouth of the Santa Cruz River (along the Atlantic coast of Patagonia) to Lake Pueyrredón (along the foothills of the Andes). Of the 17 nominal species, only six are considered valid, i.e., Trophon sowerbyi new name (replacement for Fusus patagonicus Sowerby, 1846 in Darwin non d'Orbigny), Trophon santacruzensis Ihering, 1897, Trophon camachoi new species, Trophon leanzai Brunet, 1997, Trophon contortus Brunet, 1997, and Trophon inornatus Pilsbry, 1897.
