Coralline red algal species diversity at a shallow rhodolith bed in warm-temperate Japan, including two new species of Roseolithon (Hapalidiales, Corallinophycidae)

This dataset contains the digitized treatments in Plazi based on the original journal article Kato, Aki, Adachi, Kenta, Iryu, Yasufumi, Baba, Masasuke (2024): Coralline red algal species diversity at a shallow rhodolith bed in warm-temperate Japan, including two new species of Roseolithon (Hapalidiales, Corallinophycidae). Phycologia 63 (6): 520-533, DOI: 10.1080/00318884.2024.2421269, URL: doi.org/10.1080/00318884.2024.2421269 ABSTRACT ARTICLE HISTORY Received 05-07-2024 Accepted 22-10-2024 Version of Record 25-11-2025 A shallow rhodolith bed at Shirasu, approximately 1 m deep, is the largest rhodolith bed, emergent only at spring low tides, in warm-temperate Japan.

Using phylogenetic analyses of psb A, rbc L and COI-5 P sequences, at least 10 species of rhodolith forming, non-geniculate coralline algae were documented. In the Corallinales, three previously reported Lithophyllum species: L. okamurae, L. neo-okamurae and L. nagaokaense were found. The remaining seven taxa comprised species of Hapalidiales, with Tectolithon sp. and Crustaphytum sp. sister to Tectolithon fluminense from Brazil and Crustaphytum taoyuanense from Taiwan, respectively.
