Though sea stars of the genus Henricia Gray, 1840 are widely used in biological studies, their species diversity in the Arctic is poorly understood. We conducted a taxonomic revision of the genus Henricia from the White Sea and examined 381 specimens of Henricia sea stars deposited in the collection of the Zoological Institute of the Russian Academy of Sciences (St Petersburg), the type collection founded by A. M. Djakonov, and our own collection. Following Madsen (1987) and Djakonov (1950), we identified six species in the White Sea: H. eschrichti (M端ller and Troschel, 1842), H. perforate (O. F. M端ller, 1776), H. scabrior (Michailovskij, 1903), H. solida Djakonov, 1950, H. sanguinolenta (O. F. M端ller, 1776) and H. pertusa (O. F. M端ller, 1776). Updated descriptions, identification keys and distribution data of these species are provided. Statistical analysis based on the set of individual characters confirmed the validity of the species H. scabrior. Synonymy of Henricia species according to Djakonov (1950) and Madsen (1987) is discussed. The accepted manuscript in pdf format is listed with the files at the bottom of this page.
