The name Danielita is proposed for a new dagmaritin genus characterized by a biserial arrangement of chambers with spine-like extensions at chamber corners and a perforated wall. Danielita differs from Dagmarita, from which it was derived, by a perforated wall and constitutes one of the peculiar evolutionary trends of the dagmaritin stock. Early dagmaritins evolved from Globivalvulina cyprica by the appearance of Sengoerina in the Capitanian and the frequently encountered association G. cyprica-Sengoerina-Dagmarita-Danielita in Turkey suggests that the evolutionary derivations of dagmaritin genera occurred very rapidly in the Capitanian.
