摘要：分子辅助的α分类学提供了探索生物多样性的新方法，并且在单靠形态学不足以确保准确的物种识别或划定物种边界的分类群中有很大的帮助。在这里，我们使用这种方法来评估Padina Adanson（网藻目，褐藻科），在墨西哥沃茨的一种常见的褐藻属的分类。Padina从太平洋和大西洋热带海岸的许多个人进行了分析，使用序列的psbA，细胞色素c氧化酶亚基I，和cox 3，以确定进化的重要单位或推定的物种。然后，cox 3序列的每个组的一些个人进行了分析，与大量的序列在Genbank中使用广义混合Yule聚结和泊松树模型的物种界定。每个样本都是使用该地区最初和最常见的描述来识别的。最后，对结果进行评价，寻找分子和形态学数据之间的相关性。我们得出的结论是，至少有12个Padina物种发生在墨西哥沃茨，10个从这里修订的样品和2个从Genbank序列推断。这项研究不仅揭示了存在的明确的物种，但也存在的神秘和多态物种，确认重新评估的重要性，适当的划界和命名的模式材料。最后，证据支持Padina ramonriès Avila-Ortiz，Pedroche & Díaz-Martínez的独立地位，这在这里得到了验证。
Abstract: Molecular-assisted alpha taxonomy has provided novel ways of exploring biodiversity, and is of great help in taxa where morphology alone is not sufficient to ensure accurate species recognition or delimit species boundaries. Here, we use this approach to assess the taxonomy of Padina Adanson (Dictyotales, Phaeophyceae), a common brown algal genus in Mexican waters. Numerous individuals of Padina from Pacific and Atlantic tropical coasts were analysed using sequences of psbA, cytochrome c oxidase subunit I, and cox3 to determine evolutionary significant units or putative species. Then, cox3 sequences of some individuals of each group were analysed with a large number of sequences available in Genbank using the generalized mixed Yule coalescent and Poisson tree processes models for species delimitation. Each sample was identified using the original and the most common descriptions in the region. Last, the results were evaluated looking for correlations between the molecular and morphological data. We concluded that at least 12 Padina species occurred in Mexican waters, 10 from samples here revised and 2 inferred from Genbank sequences. The study not only revealed the existence of well-identified species, but also the existence of cryptic and polymorphic species, confirming the importance of reassessing type material for proper delimitation and nomenclature. Finally, the evidence supported the independent status of Padina ramonribae Avila-Ortiz, Pedroche & Díaz-Martínez, which is validated here.
