![]() This report increases the species richness of kelps for the Magellan Sub-Antarctic Channels from two to three confirmed species ( L. The morphological identification and molecular phylogeny based on nuclear (ITS1) sequences revealed that these populations of Lessonia are within the lineage of L. spicata, specifically on rocky shores of Torpedo Island and Castillo Channel. In the ecological assessments of the KNR in 2018 we found populations of L. This finding has implications for macroalgal biogeography and conservation concerns in the Chilean coast. The present study is the first report of the species Lessonia spicata, “huiro negro”, in the Magellan Sub-Antarctic channels. The Katalalixar National Reserve (KNR) lies in an isolated marine protected area of Magellan Sub-Antarctic channels, which represent an important area for marine biodiversity and macroalgal conservation. A new record of kelp Lessonia spicata (Suhr) Santelices in the Sub-Antarctic Channels: implications for the conservation of the “huiro negro” in the Chilean coast.
