Abstract
Information collected from a complete female juvenile individual of Gray's beaked whale (Mesoplodon grayi) stranded on the Guanaqueros coast, Coquimbo Region in Chile (30°S) is provided. Difficulties to differentiate specimens of Gray's beaked whale and Hector’s beaked whale (M. hectori) are discussed based on the use of diagnostic phenotypic characters, such as differences in color patterns and position of teeth on the lower jaw. The identification of the studied specimen as Gray's beaked whale was supported by a detailed review of cranial characters and molecular analyses. Finally, we provide an updated list containing all known Chilean records for this species. Se proporciona información del registro más completo de Mesoplodon grayi (Ziphiidae) que se conoce para Chile y que corresponde a una hembra juvenil varada en la costa de Guanaqueros, Región de Coquimbo (30°S). Se discuten los problemas de determinación de Mesoplodon grayi con respecto a M. hectori en base a la utilización de caracteres fenotipicos generales como patrones de coloración. La asignación a Meso-plodon grayi se apoyó en la revisión detallada de caracteres craneales y un análisis molecular. Además, se presenta un listado actualizado con todos los registros conocidos para esta especie en las costas de Chile.

Our gratitude to P. Schiappacasse for the support in the transfer of the specimen from Coquimbo and to P. Rivera for the information provided on the specimen from Iquique. Our gratitude to E. Mutschke, from the Institute of Patagonia (ISP), the University of Magallanes for providing us with photographs of material from the ISP collection as well as important data. A special thanks to V. Rivas who made and edited the photographs of the MNHN/MAM 1972 skull. Molecular analyses of the specimen were made possible thanks to the support of the FONDECYT 1180366 (GD) project.
