Goodayia rostellatum gen. n., sp. n. is described from the open slope of the Black Sea along the northwestern part of the Crimean Peninsula (160 m water depth). The test of this very delicate, organic-walled, monothalamous (single-chambered) foraminifer is elongated and becomes wider from the middle to the apertural end. Test wall consists of two layers, and the protoplasm is separated from the inner layer by a more or less distinct space. The protoplasm is finely granular, homogeneous, without foreign inclusions. The single terminal apertural structure has an asymmetric, beak-like shape with the aperture located under the beak. The nucleus is situated more or less in the middle of the test. The shape and size of the test, the presence of two membranes, and the single terminal aperture are the features reminiscent of the genera Gloiogullmia and Rhynchogromia. However, the new genus has significant differences from these taxa, notably the absence of any foreign mineral or organic particles adhering to the test wall, and the beak-shaped apertural structure.
