Descripción
Non-indigenous species represent a significant threat to marine biodiversity, and accurate taxonomic identification is critical for effective management. This study revisits the long-standing record of the Australian sea anemone Oulactis muscosa in Argentina, which has been cited in numerous studies for nearly 50 years. We conducted a comprehensive taxonomic revision of specimens from Mar del Plata, Argentina, using both morphologi-cal and molecular analyses. Our findings reveal a persistent taxonomic error: the speci-mens belong to a different species. Detailed morphological comparisons and genetic se-quencing of mitochondrial and nuclear markers re-identified the specimens as Anthopleu-ra correae. This species is native to Brazil and is distributed from Ceará to Santa Catarina. This represents the first record of an Anthopleura species in Argentina, extending its known distribution. Genetic analyses confirmed the re-identification, showing no signifi-cant divergence between the Argentine and Brazilian specimens, while revealing notable differences from O. muscosa. We highlight the importance of rigorous taxonomic ap-proaches integrating both morphological and molecular data to prevent misidentifica-tions, which is particularly crucial when identifying potential invasive species. This study clarifies the taxonomic status of a regionally distributed species and contributes to the ac-curate inventory of sea anemones in Argentina.
