The Southwest Atlantic is notable for having extensive reef areas cemented by nongeniculate coralline red algae. Based on an analysis of four genetic markers and morpho-anatomical features, we clarify the species of Harveylithon in the tropical and warm temperate Southwest Atlantic. Species delimitation methods (mBGD, ABGD, SPN, and PTP), using three markers (psbA, rbcL, and COI), support the recognition of three new species: H. catarinense sp. nov., H. maris-bahiensis sp. nov., and H. riosmenum sp. nov., previously incorrectly called Hydrolithon samoënse. Our findings highlight the importance of using an approach with several lines of evidence to solve the taxonomic status of the cryptic species.
西南大西洋以广泛的珊瑚礁区域为特色，这些珊瑚礁区域由非关节珊瑚状红藻胶结而成。基于对四个遗传标记和形态解剖特征的分析，我们澄清了热带和暖温带西南大西洋中 Harveylithon 的物种。物种划分方法（mBGD、ABGD、SPN 和 PTP），使用三个标记（psbA、rbcL 和 COI），支持识别三种新物种：H. catarinense sp. nov.、H. maris-bahiensis sp. nov. 和 H. riosmenum sp. nov.，以前被错误地称为 Hydrolithon samoënse。我们的发现强调了使用多种证据方法来解决隐种分类地位的重要性。
