biostudies-literatureUnknown61Yiu SKF<i>Tubastraea</i> is a genus of azooxanthellate scleractinian corals belonging to the family Dendrophylliidae, which are commonly called sun corals. This genus currently has only seven recognized species. In this paper, we report three new species of <i>Tubastraea</i>, including <i>T. dendroida</i> sp. nov., which has a tree-like colony, <i>T. violacea</i> sp. nov., which has violet polyps, and <i>T. chloromura</i> sp. nov., which has olive green polyps. These species are distinct in their septal structures, as well as their <i>rDNA</i> sequences including the entire <i>ITS1</i>, <i>5.8S</i> and <i>ITS2</i>, and a segment of the <i>18S</i> and <i>28S</i> genes.Zoological studiese45https://www.ebi.ac.uk/biostudies/studies/S-EPMC9745568biostudies-literatureThree New Species of the Sun Coral Genus <i>Tubastraea</i> (Scleractinia: Dendrophylliidae) from Hong Kong, China.PMC9745568Yiu SKFQiu JWfalseThree New Species of the Sun Coral Genus <i>Tubastraea</i> (Scleractinia: Dendrophylliidae) from Hong Kong, China.<i>Tubastraea</i> is a genus of azooxanthellate scleractinian corals belonging to the family Dendrophylliidae, which are commonly called sun corals.
