New records of Lontra longicaudis (Olfers, 1818) (Carnivora, Mustelidae) in El Salvador

Lontra longicaudis Olfers, 1818 (Neotropical Otter) has been poorly studied in El Salvador. We report sightings and traces of L. longicaudis which were found in Río Angue, in the department of Santa Ana, and Río Sapo, Río Negro, and Quebrada de Perquín, in the department of Morazán. Moreover, we review the sight records of the species in the scientific literature, the mammal collection of the University of California, Los Angeles, and citizen reports with verifiable evidence. This is the first compilation of information on L. longicaudis occurrences in El Salvador
