Contracaecum osculatum (Rudolphi, 1802) s.l.
Host: Otaria flavescens (Shaw)
Site in host: stomach
Locality: Argentina
References: Carrara (1952)
Notes: Carrara (1952) identified these nematodes as C. osculatum . However, since C. osculatum s.s. parasitize seals from the North Hemisphere (see Mattiucci and Nascetti 2008) we re-assigned this taxa as C. osculatum s.l.
