The species has not been collected from its type locality on the Pacific coast of Japan since 1927, and seems to have become extinct from the vicinity. To molecularly characterize L. japonica, we extracted DNA from topotype material of L. japonica collected in 1927, analyzed nine genes using Illumina next-generation sequencing, and compared these data with sequences from modern samples of similar red algae collected from the Japan Sea coast of Japan. Both morphological and molecular data from modern samples and historical specimens (including the lectotype and topotype) suggest that the specimens from the Pacific and Japan Sea coasts of Japan should be treated as a single species, and that L. japonica is phylogenetically separated from the genus Liagora. Based on the phylogenetic results and an examination of reproductive structures, we propose Otohimella japonica gen. et comb. nov., characterized morphologically by diffuse carposporophytes, undivided carposporangia, and the involucral filaments initiated only from the subcortical cell on the supporting cell.} }
