Bothriolepiform antiarchs (Pisces, Placodermi) from the devonian of Central Kazakhstan

Bothriolepiform antiarchs (Placodermi, Antiarchi) are represented by two genera in the Devonian of Central Kazakhstan: Bothriolepis Eichwald (Bothriolepididae) and Tenizolepis Malinovskaja (Dianolepididae). The first includes five species: B. babichevi Malinovskaja, 1992, B. kassini Malinovskaja, 1988, B. amankonyrica Malinovskaja, 1988, B. nikitinae Malinovskaja, 1988, and B. tastenica Malinovskaja, 1988; the second includes only two valid species, T. asiatica (Obrucheva, 1955) and T. rara Malinovskaja, 1977. As type collections of bothriolepiform antiarchs of Central Kazakhstan were revised, the diagnoses were emended and the postcranial exoskeleton was reconstructed. The classification of the order is discussed and a new family, Tubalepididae fam. nov., is established.
