We investigated species referred to as ‘Ahnfeltiopsis flabelliformis’ from the Far Eastern seas of Russia as well as Besa catenata (Yendo) M.S.Calderon & S.M.Boo from Mie Prefecture (Shima Peninsula, Japan, near to its type locality) morphologically and by analysis of sequences of plastid rbcL and mitochondrial COI-5P genes. Morphological and phylogenetic analyses showed that Ahnfeltiopsis flabelliformis does not occur in the Far Eastern seas. All algae previously identified as ‘A. flabelliformis’ from Russian waters belong to two morphologically and genetically distinct species that should be referred to the genus Besa as B. divaricata (Holmes) M.S.Calderon & S.M.Boo and B. japonica (Suringar) A.V. Skriptsova & S.Y.Shibneva, comb. nov. We found an unattached form of B. divaricata and named it as B. divaricata f. ahnfeltioides A.V.Skriptsova & S.Y.Shibneva based on its morphological and ecological features.
