The Peristerniinae (Mollusca: Gastropoda, Buccinoidea, Fasciolariidae) from the Neogene of Venezuela

The Latirus-group of Peristerniinae Tryon, 1881 present in the early Miocene, late Burdigalian, Cantaure Formation assemblage of Venezuela, and other less well-known Venezuelan Miocene assemblages, is described and discussed. Seven species taxa representing three genera are present in the northern Venezuelan Miocene assemblages, six are new to science; Hemipolygona snyderi nov. sp., Hemipolygona carrizalensis nov. sp., Polygona praeanapetes nov. sp., Polygona barbascoensis nov. sp., Polygona sepulcralis nov. sp. and Polygona buenevaraensis nov. sp. The presence of Pustulatirus tumbeziensis (Olsson, 1932) in the Cantaure Formation of Venezuela is confirmed. For all three genera, Pustulatirus, Hemipolygona and Polygona these represent the earliest records in the Caribbean portion of the Tropical American Neogene Gatunian biogeographical province.
