    The diamond stingray (Hypanus dipterurus) is a species of cartilaginous fish that,according to the IUCN, is globally in a vulnerable state of conservation and its popula-tions show a decline. New records of this ray species in southern Peru and northernChile have expanded their known range. The species is distributed in the EasternCentral Pacific, from southern California to San Andres, on the central coast of Peru,but is poorly known in Chile. Angler records mined from social media and historicaldata confirmed the presence of H. dipterurus along southern Peru and northern Chile,extending southward over 1250 km. A species distribution model (SDM) based onprevious global occurrences combined with oceanographic layers was built to identifyareas of potential and undocumented presence of H. dipterurus. The SDM showedhigh accuracy (area under the curve = 0.95) and predicted the potential presence ofH. dipterurus along vast areas of the Peruvian and Chilean coasts, where the presenceof the species was poorly documented. Comprehensive surveys are required tounderstand the distribution, population dynamics, habitat requirements, and threatsto effective conservation efforts in the southern region of its distribution range.
