Abstract [en]

A new osteostracan genus and species. Victoraspis longicornualis n. gen., n. sp., is described based on material from Rakovets', present day Ukraine. This new taxon shares characters with the two genera Stensiopelta DENISON, 1951 and Zychaspis JANVIER, 1985. A phylogenetic analysis supports the position of Victoraspis as the sister group to a monophyletic Stensiopelta, while the interrelationships of the various species of Zychaspis are poorly resolved. A morphometric analysis is carried out in an attempt to further resolve the taxonomic affinity. This analysis groups all examined Zychaspis species closely together, and further supports the establishment of Victoraspis as separate, genus.
