Abstract We present the first report of parasitism by Sarcoptes scabiei (Linnaeus, 1758), in a sechuran fox “Lycalopex sechurae”. Sarcoptes scabiei is a mite that produces sarcoptic mange, which can lead to the death of the animal host and can cause epidemic episodes in wildlife communities. The sechuran fox was collected by the environmental police from a citizen who reported the animal. It was sent to a veterinarian specializing in wildlife, “Clinica Mansion Mascota”, in Guayaquil, Ecuador. Immediate physical examination showed crusts on its skin, and samples of skin and blood were collected and analyzed. The skin samples were analyzed using a microscope at 40x magnification in the clinic. In addition, skin and blood samples were sent to a private laboratory for further analyses. Both analyses were positive for S. scabiei infection. It is the second report of S. scabiei in a new wildlife species in the Guayas province of Ecuador within less than a year. These events cause concern due the possibility of biological community transmission. Since domestic and feral animals are considered habitual spreaders of this disease, management through ethical procedures such as adoption, medical treatment and neutering campaigns, and awareness-raising projects with empathetic approach are recommended.
