The name Paynita is proposed for a new dagmaritin genus
from the upper Changhsingian (Permian) carbonates of the
Southern Biofacies Belt in Turkey. Paynita permotaurica differs from its ancestor Paradagmarita monodi by a hookshaped fold in the apertural flap terminating systematically
against the inner surface of the septal wall to protect the
opening from one chamber to the other. It is associated
with several species of dagmaritins, belonging to Paradagmarita, Paradagmacrusta, Louisettita, Dagmarita, Danielita,
and Bidagmarita. The overall analysis of dagmaritins reveals
that the stratigraphic range of the group is from Wordian to
Changhsingian. The revised chronostratigraphy in the type
area of the genus Sengoerina indicates that this oldest dagmaritin was derived from Globivalvulina cyprica in the Wordian. The first occurrences of genera Dagmarita and Danielita
postdate the first occurrence of Sengoerina in the Wordian. Paynita is the last evolutionary step of the SengoerinaDagmarita-Crescentia-Paradagmarita lineage characterized
by a planar apertural flap whose structure practically remained unchanged during the process of evolution. Paynita is the first genus in this lineage displaying fold in the apertural
flap similar to the evolution of Louisettita from Dagmarita.
