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° of latitude (~1000 km) to central Chile (?32°) during strong negative ENSO conditions. © 2024 The Author(s).
