Abstract

We report the presence of Pristigenys serrula Gilbert 1891 off Zapallar (-32.568253, -71.464225), central Chile, during the ENSO 2023-2024 event. Morphology and a partial fragment of the mitochondrial markers cytochrome oxidase 1 (COX1) and 16S rDNA identified one specimen fished by artisanal fishermen. This report extends the known southern range limit of P. serrula by 9 degrees of latitude (similar to 1000 km) to central Chile (-32 degrees) during strong negative ENSO conditions.
