Phocoena dioptrica Lahille 1912, Ann. Mus. Nat. Hist., Buenos Aires, 23: 269.
Type Locality: Argentina, Buenos Aires, "capturado en Punta Colares, cerca de Quilmes".
Vernacular Names: Spectacled Porpoise.
Synonyms: Phocoena stornii Marelli 1922 .
Distribution: Southern hemisphere: cold-temperate waters; Uruguay, Argentina; Falkland, South Georgia, Heard, Macquarie and the Auckland Isls, perhaps Kerguelen Isls. Perhaps circumpolar, see Baker (1977).
Conservation: CITES – Appendix II; IUCN – Data Deficient.
Discussion: Reviewed by Brownell (1975 a, Mammalian Species, 66). Barnes (1985) proposed Australophocoena to house this species, but Rosel et al. (1995) did not find the generic separation warranted. Phocaena obtusata is synonymous with Cephalorhynchus eutropia . See Goodall et al. (1988).
