Five new species in the genus Marginella from the Eastern Cape, South Africa are described. Four species in the subgenus Nataliamarginella S.G. Veldsman, 2017: M. (N.) mbasheensis n. sp., M. (N.) mlambomkuluensis n. sp., M. (N.) mtataensis n. sp., and M. (N.) muratovi n. sp.; and one species in the subgenus Punctamarginella S.G.Veldsman, 2017 M. (P.) transovula n. sp. The new species are compared to their closest congeners within their respective subgenus with regards to their shell morphological features and locality. The species described here are all found deep water (50-550 m) along the central-northern Eastern Cape, between the Great Kei River (50 km north of East London) and Mbotyi (25 km north of Port St. Johns), South Africa, a portion of the 34 6region previously known as Transkei. Most of the closest congeners regarding shell morphology are found in KwaZulu-Natal at least 70 km north-east and further, with a region previously named Pondoland separating them. Very few Marginella species are adapted to live in the specific habitat of the Pondoland region. |
