- Abstract
The systematic of bladed Bangiales is suffering significant changes at a global level, due to the inclusion of new genera, such as Pyropia, and the incorporation of molecular evidence. In Chile, the application of molecular tools has shown a high diversity of species in genera Porphyra and Pyropia, with species delimitations that do not correspond to species defined on the basis of morphological characters. In Peru, historical records recognized five species of Porphyra, however, their taxonomic status has not yet been deeply contrasted with molecular evidence. Therefore, this work aimed to explore the local diversity of species of Porphyra and Pyropia in Marcona, Peru, characterizing 11 specimens with the mitochondrial and chloroplast markers COI and rbcL respectively. The phylogenetic analysis identified one species of Porphyra (Porphyra sp. CHF) and three Pyropia species (Pyropia orbicularis, Py. suborbiculata and Pyropia sp. CHI). There were no coincidences with the historical records of Porphyra. Three of the four species found have a distribution range encompassing Chile and Peru. This work is a first step towards a characterization of the specific diversity of the algal resource known as "cochayuyo" in Peru.
