Confirmation of two infraspecific taxa of a coralline red alga described from Sri Lanka as independent species
Key points of this research
- Lithophyllum okamurae included seven infraspecific taxa described from the Indo-Pacific region.
- The taxonomic status of the two infraspecific taxa described from Sri Lanka had yet to be assessed using molecular data.
- This study revealed that the seven infraspecific taxa were identified as L. okamurae and five distinct species.
Content of research
Lithophyllum okamurae is a coralline red alga that firmly deposits calcium carbonate on cell wall. This study assessed that the taxonomic status of two infraspecific taxa of this species described from Sri Lanka based on molecular analyses and detailed morpho-anatomical observations of their type material. Our results showed that both taxa could be treated as independent species and were distinct species from L. okamurae. Considering previous revisions to the other five infraspecifc taxa, this study finally confirmed that the seven infraspecific taxa were identified as six species. Of these, only L. okamurae is distributed along the coasts of Japan.
