Chelemys delfini Cabrera 1905
Chelemys delfini Cabrera 1905, Rev. Chilena Hist. Nat., 9: 15.
Type Locality: Chile, Magallanes Prov., Straits of Magellan, Punta Arenas.
Vernacular Names: Magellanic Long-clawed Akodont.
Distribution: Southernmost Chile.
Discussion: Taxonomic status and distributional extent require refinement—treated as a subspecies of C. megalonyx by Mann (1978) and Tamayo and Frassinetti (1980); retained as a species by Osgood (1943) and Reig (1987). Johnson et al. (1990) recognized C. delfini and C. macronyx as definable forms, separable by body size, in the Patagonian region of extreme S Chile.
