DESCRIPTION
Test moderate to large in size and fusiform or relatively rhomboidal in shape. The four-layered wall has a tectum, lower and upper tectorium and diaphanotheca.
Septa
regularly to irregularly folded throughout the test. Chomata massive, symmetrical and quadrate in shape.
REMARKS
In accordance with the generic definitions discussed by
Ishii (1957
,
1958
), several species originally assigned to
Fusulina
were reassigned to the genus
Beedeina
in some recent studies (
Villa 1995
;
Leven 1998
;
Leven & Gorgij 2008
,
2011
; and this study) based on their morphological features, such as the shell shape and lack of axial fillings. For this reason,
Beedeina paradistenta
which was originally described in the genus
Fusulina
by Safonova (in Rauzer-Chernousova
et al.
1951) is considered as a species of the genus
Beedeina
in this study.
