Chondracanthus chamissoi is a red seaweed of economic importance and of wide distribution in the Peruvian and Chilean coasts. Despite its relevance, genetic connectivity studies of this species have not been conducted in a wide latitudinal range. Therefore, the objective of this phylogeographic study is to report the genetic-population status of C. chamissoi in the Peruvian coast. Phylogenetic and phylogeographic analyzes were carried out with 143 sequences of the mitochondrial marker COI and 36 sequences of the chloroplast marker rbcL of specimens distributed in 18 Peruvian localities. The phylogeny using both markers indicates that C. chamissoi forms a single gene lineage in the Peruvian coast. The geographic distribution of the COI and rbcL haplotypes of C. chamissoi suggests the absence of phylogeographic breaks in the Peruvian coast. At the species level, the genetic diversity indices of C. chamissoi are very low, probably associated with its high passive dispersion, in combination with ENSO events and extractive pressure. Evidence of demographic history and star-like COI and rbcL haplotypes networks suggest that this species has gone through an event of recent population expansion. The seven populations analyzed in Peru reveal to be very similar genetically. The genetic non-structuring of C. chamissoi inferred from COI sequences is possibly related to a high level of extrinsic dispersion, attributed to its vegetative propagation characteristics and substrate availability.
