Genus Depratina Solovieva, 1996 View in CoL
TYPE SPECIES. — Schwagerina prisca Deprat, 1912 by original designation.
ASSEMBLAGE. — The Depratina assemblage in this study are Depratina chernovi ( Fig. 10A, B View FIG ), Depratina convoluta ( Fig. 10C View FIG ), Depratina dubia ( Fig. 10D, E View FIG ), Depratina paratimanica ( Fig. 10F, G View FIG ), Depratina posadai ( Fig. 10H, I View FIG ), Depratina prisca prisca ( Fig. 10 View FIG J-M), Depratina prisca sphaeroidea ( Fig. 10N, O View FIG ), Depratina prisca timanica ( Fig. 10 View FIG P-S) and Depratina sitteri ( Fig. 10T, U View FIG ).
DESCRIPTION
Test small in size and short-inflated fusiform to subspherical in shape. The wall thin and three-layered, composed of tectum, thin lower and upper tectorium. Septa thin and plain across the centre of the test, slightly folded only in polar region of last one or two volutions. Chomata massive, symmetrical and rounded to subquadrate in shape.
REMARKS
The dominantly small sized and nearly globular or shortinflated fusiform shaped Profusulinella species were referred to as the “ prisca group” by Rauzer-Chernousova et al. (1951). Later, the “ prisca group” was assigned to the genus Depratina Solovieva in Rauzer-Chernousova, Bensh, Vdovenko, Gibshman, Leven, Ya Lipina, Reitlinger, Solovieva & Chediya, 1996. The species belonging to the genus Depratina differ from other Profusulinella species by having relatively globular or short-inflated fusiform test, smaller L/D ratio and poorly developed chomata. Hence, in this study the species belonging to the “ prisca group” (Rauzer-Chernousova et al. 1951) and the species which have same features such as Depratina chernovi , Depratina convoluta , Depratina paratimanica , Depratina posadai , Depratina prisca sphaeroidea and Depratina dubia are assembled in the genus Depratina .
