Abstract

We describe two new genera and species of monothalamous foraminifera from the Crimean region and the north-western part of the Black Sea. The test of Bellarium rotundus gen. et sp. nov. is up to 650 μm long, more or less rounded to broadly oval, and with terminal necks ending in apertures that are often flared. The organic wall is very thin, without agglutination. The protoplasm is finely granular, homogeneous, with many vacuoles and foreign inclusions and a small (25–80 μm) nucleus. The presence of two terminal apertures and the organic wall are the features reminiscent of two other organic-walled genera, Shepheardella and Tinogullmia. However, the test of the new genus is much more rounded than that of either of these two genera, and the apertural structures are different. The test of the second new genus and species, Krymia fusiformis gen. et sp. nov., is elongated, up to 470 μm long and spindle-shaped, with two apertures situated at the ends of terminal, tubular extensions of the test. The wall is flexible and composed of organic material overlain by finely agglutinated particles. Long, needle-like spicular structures, possibly ingested particles, are often visible within the cytoplasm. Krymia differs from Phainogullmia in the more clearly spindle-like test shape and the nature of the test wall. These two new species increase the number of monothalamous foraminifera described from the Black Sea to ten, although many others remain undescribed.
