Stenurus sp.

Host: Lagenorhynchus obscurus (Gray)

Site in host: intestine

Locality: Playa Bonita (43º21'S, 65º03'W), Chubut province

References: Loizaga de Castro et al. (2014)

Notes: Species of Stenurus are parasites of lungs and cranial sinuses of cetaceans (Anderson et al. 2009). The presence of specimens of Stenurus sp. in the intestine of the dusky dolphin could be related to an accidental transfer of these nematodes from the lungs to the intestine when the dolphin was necropsied.
