Cercopithifilaria bainae and Cercopithifilaria grassii (Spirurida, Onchocercidae) are filarioids inhabiting the skin of dogs worldwide. The microfilariae of a third species namely, Cercopithifilaria sp. II sensu Otranto et al. 2013, have been morphologically and molecularly characterized but scientific knowledge of this parasite is minimal. The first case of infection of a red fox (Vulpes vulpes) with the filarioid Cercopithifilaria sp. II is herein described in Castro Marim, Portugal. Microfilariae from skin sediment of the fox's ear were morphological characterized, and the identification was confirmed molecularly in samples from skin sediment, skin samples, and from Rhipicephalus sanguineus group ticks collected from the animal (99% homology with Cercopithifilaria sp. II). Studies should evaluate if red foxes might play a role in the maintenance and distribution of Cercopithifilaria sp. II infection in dog populations.
