A new early Oxfordian coleoid cephalopod, <i>Trachyteuthis covacevichi</i> n. sp., is described from northern Chile. It represents the first Late Jurassic Palaeopacific vampyropod and thus considerably extends the palaeogeographic distribution of trachyteuthids. In general, <i>Tr. covacevichi</i> n. sp. possesses a gladius typical for the genus, but wider than in other species. Similarities between <i>Tr. covacevichi</i> n. sp., <i>Tr. palmeri</i> from the Oxfordian of Cuba and <i>Tr</i>. sp. from the Kimmeridgian of Europe confirm a Caribbean Seaway between the Tethys and the Palaeopacific during Late Jurassic times. Morphologically, the wide gladius of <i>Tr. covacevichi</i> n. sp. supports a close phylogenetic relationship between <i>Teudopsis</i> and <i>Trachyteuthis</i>. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.200700012" target="_blank">10.1002/mmng.200700012</a>
