A remarkable new genus of Carangidae from the Upper Paleocene of Turkmenistan (Osteichthyes: Perciformes)

Abstract. A new genus and species of Carangidae, Uylyaichthys eugeniae gen. et sp. n., is described from the Upper Paleocene (middle part of the Danata Formation) of Turkmenistan. It belongs to the subfamily Trachinotinae s. str. and differs from all known members of the family in the combination of low vertebral count (21 or posibly 22), paraspenoid strongly curved mesially, and unique predorsal formula 0/0+0+0/1/. Uylyaichthys is considered to be a sister taxon for Trachinotus + Paratrachinotus, and Trachinotinae s. str. regarded as a sister group of Scomberoidinae. The genus Lichia is excluded from Trachinotinae s. str. and considered to be a sister taxon of Scomberoidinae + Trachinotinae s. str.
