Aonyx Lesson, 1827 . Manual de Mammalogie, p. 157.

TYPE SPECIES: Aonyx Delalandi Lesson, 1827 (= Lutra capensis Schinz, 1821) by subsequent designation (Palmer, 1904).

SYNONYMS: Anahyster Murray, 1860; Paraonyx Hinton, 1921 .

COMMENTS: Osgood (1932), Ellerman and Morrison-Scott (1951), and Coetzee (1977b) considered Amblonyx Rafinesque, 1832, as congeneric; here separated based on Harris (1968), Medway (1977), and van Zyll de Jong (1972, 1987). There is little question that capensis and congicus are sister species.
