TYPE SPECIES. — Fusulinella girtyi Dunbar & Condra, 1927 by original designation.
ASSEMBLAGE. — The Beedeina assemblage in this study includes: Beedeina cf. nytvica callosa ( Fig. 13H View FIG ), Beedeina elegans ( Fig. 13C, D View FIG ), Beedeina minuta Akbaş , n. sp. ( Fig. 13E, F View FIG ), Beedeina paradistenta ( Fig. 13I View FIG ), Beedeina pseudoelegans pseudoelegans ( Fig. 13 View FIG J-M), Beedeina pseudoelegans keltmensis ( Fig. 13N View FIG ), Beedeina samarica ( Fig. 13O, P View FIG ), Beedeina schellwieni ( Fig. 14 View FIG A-D), Beedeina tauridiana Akbaş , n. sp. ( Fig. 14E, F View FIG ) and Beedeina timanica ( Fig. 14H, I View FIG ).
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.
