Abstract
A new istiodactylid pterosaur, <i>Nurhachius luei</i> sp. nov., is here reported based on a complete skull with mandible and some cervical vertebrae from the lower part of the Jiufotang Formation of western Liaoning (China). This is the second species of <i>Nurhachius</i>, the type-species being <i>N. ignaciobritoi</i> from the upper part of the Jiufotang Formation. A revised diagnosis of the genus <i>Nurhachius</i> is provided, being this taxon characterized by the presence of a slight dorsal deflection of the palatal anterior tip, which is homoplastic with the Anhangueria and <i>Cimoliopterus. N. luei</i> sp. nov. shows an unusual pattern of tooth replacement, with respect to other pterodactyloid species. The relationships within the Istiodactylidae and with their closest taxa are investigated through a phylogenetic analysis by parsimony.
