Note: When describing Zonaria rosea, C. Agardh cited Dictyota rosea Lamouroux as a synonym. This unpublished species was said by Lamouroux (1813: 272) to come from "Ind. orient''. We have not encountered any information on the intended type. The conspecificity of Zonaria rosea and Mastophora macrocarpa was proposed by Setchell (l.c.). Verheij (1994: 111–112) added Mastophora affinis as a synonym. The protologue of Mastophora affinis described and illustrated three specimens, each consisting of a piece of coralline-encrusted Polyopes constrictus (Turner) J. Agardh, all said to have come from Sikka on Flores Island (not a Siboga Expedition station). Adey & Lebednik (1967: 14), however, found that the fragment in Foslie's herbarium was marked no. 1262 from Siboga Expedition station 258 (Tual Anchorage, Kei Islands, 12 December 1899) and these data were confirmed by Verheij & Woelkerling (1992: 276), who found two of the original specimens at L. The third specimen, which was subsequently located at L, turned out to be from Siboga Expedition station 58 (anchorage off Seba, Sawu Island) so that what was previously considered a holotype proved to be a lectotype (Woelkerling & Verheij, 1995: 35). Foslie's error in stating that all three specimens came from Sikka possibly is related to the fact that Weber-van Bosse (1921: 245) reported a collection of Polyopes (as P. bushiae Farlow) made by her at that locality in 1888. She failed to record Polyopes from the Siboga stations 58 and 258, however, apparently overlooking the material filed with Mastophora affinis.
