Terranova galeocerdonis (Thwaite, 1927) (Nematoda: Anisakidae) from Carcharias taurus (Chondrichthyes: Odontaspididae) off Argentina, with comments on some related species.
The purpose of this study was to study and redescribe Terranova galeocerdonis (Thwaite, 1927) from Carcharias taurus off Argentina. Its fourth larval stage was described, measured and illustrated for the first time. The host and geographical range of this species is extended into the southwestern Atlantic Ocean. When the present material was compared with T. rochalimai (Pereira, 1935) and T. ginglymostomae Olsen, 1952, it was considered that both morphological and morphometrical differences between the three species did not justify differentiation at the specific level. As a result, T. rochalimai and T. ginglymostomae are considered to be junior synonyms of T. galeocerdonis.
