Genus Solovievaia Vachard & Le Coze, 2018

Ovatella Solovieva in Rauzer-Chernousova, Bensh, Vdovenko, Gibshman, Leven, Ya Lipina, Reitlinger, Solovieva & Chediya, 1996: 93.

Solovievaia Vachard & Le Coze, 2018: 1-6 (nomen novum for Ovatella Solovieva, 1996).

TYPE SPECIES. — Profusulinella ovata Rauzer-Chernousova, 1938 by original designation.

ASSEMBLAGE. — The recovered Solovievaia assemblage in this study are as follows; Solovievaia arta (Fig. 9J), Solovievaia ex gr. nuratavensis (Fig. 9K), Solovievaia ovata ovata (Fig. 9L, M), Solovievaia ovata nytvica (Fig. 9N, O), Solovievaia simplex n. comb. (Fig. 9P), Solovievaia subovata (Fig. 9Q) and Solovievaia syzranica n. comb. (Fig. 9R, S).

DESCRIPTION

Test small to moderately in size and elongate-ovoid or cylindrical in shape. Thin three-layered wall with tectum, lower and upper tectorium. Septa plain across the centre of the test and slightly folded at the end of the axis. Chomata massive, symmetrical and subquadrate in shape.

REMARKS

According to Rauzer-Chernousova et al. (1951), the species group of the Profusulinella Rauzer-Chernousova & Belyaev in Rauzer-Chernousova, Belyaev & Reitlinger, 1936, which predominantly characterized by elongate test were classified under the “ ovata group”. Later, this group was transferred to the genus Ovatella Solovieva in Rauzer-Chernousova, Bensh, Vdovenko, Gibshman, Leven, Ya Lipina, Reitlinger, Solovieva & Chediya, 1996 by Rauzer-Chernousova et al. (1996) without any detailed taxonomic list. In recent studies, Vachard & Le Coze (2018) emended the name Ovatella as Solovievaia Vachard & Le Coze, 2018 because of the prior use of the name Ovatella for a gastropod genus Ovatella Bivona-Bernardi, 1832 by Bivona-Bernardi (1832). The identified species in this study, Solovievaia arta, Solovievaia ovata ovata, Solovievaia simplex n. comb. and Solovievaia syzranica n. comb., are included in the genus Solovievaia because of their morphologic features, particularly their elongate shells.
