| Abstract |
Three new species records, Axinella arctica (Vosmaer, 1885), Semisuberites cribrosa (Miklucho-Maclay, 1870), and Cladocroce spatula (Lundbeck, 1902), and one new combination, Plicatellopsis bowerbanki (Vosmaer, 1885) comb. nov. from eastern Canada are described. The four species have similar growth forms which are either fan or cup-shaped with obvious stalks. This is the first description of a member of the genus Plicatellopsis in the North Atlantic, and the second record of the genus in the northern hemisphere. The four species described here have a history of misidentification in eastern Canada and this work aims to guide future identifications in the region. |
