Abstract Species of the red algal genus Meristotheca are important natural resources that can be used directly as food for human consumption well raw materials extraction carrageenan. Despite being harvested in Japan and Korea, a comprehensive taxonomic study specimens from these two countries to elucidate their phylogenetic position is lacking. In this study, we aimed clarify identities currently regarded M. papulosa Korea by analyzing morphological molecular data. As result, recognized new species, pilulaora sp. nov. resurrected japonica Japan. The entities have long been identified exhibit similar external morphologies. They appeared independently concatenated tree COI-5P rbc L could also distinguished morphologically cystocarps (blade margins ; marginal proliferations ), spinose (absent present number cortical cell layers (two 4–8 ). DNA analysis local populations showed 11 haplotypes on Jeju Island with no apparent geographical structure. High genetic diversity occurrence unique southern may provide basis population high thermal tolerance. These findings strengthened our understanding species provided insights into conservation, management, haplotype selection future cultivation economically species.
