A new istiodactylid pterosaur, Nurhachius luei 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 Nurhachius, the type-species being N.
ignaciobritoi from the upper part of the Jiufotang Formation. A revised
diagnosis of the genus Nurhachius 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 Cimoliopterus.
N. luei 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.
