Gourmya magnifica sp. nov. (Gastropoda: Cerithiidae), a new species from the Miocene of Java

Gourmya belongs to a group of molluscs, which originated during the Paleogene in the Western Tethys and along the Eastern Atlantic coast but then established in the IWP Region during the Neogene. Similar patterns have been observed by Harzhauser et al. (2007, 2008) for tridacnine bivalves and certain strombids. In this paper we describe an extremely large species from the Middle Miocene Langhian of Java; Gourmya magnifica sp. nov.
