A new early Oxfordian coleoid cephalopod, Trachyteuthis covacevichi 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, Tr. covacevichi n. sp. possesses a gladius typical for the genus, but wider than in other species. Similarities between Tr. covacevichi n. sp., Tr. palmeri from the Oxfordian of Cuba and Tr. 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 Tr. covacevichi n. sp. supports a close phylogenetic relationship between Teudopsis and Trachyteuthis . (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
