Inia is a genus of river dolphins from South America. It contains one to three species.
Taxonomy
The genus was described by Alcide d'Orbigny in 1834 when Delphinus geoffrensis, described by Henri Marie Ducrotay de Blainville in 1817, was recognized to be a unique taxon. A 1998 classification[1] listed a single species, Inia geoffrensis, in the genus Inia, with three recognized subspecies. Most of the scientific community accepted this single species classification, as did the IUCN.[2] In 2012 the Society for Marine Mammalogy[3] started considering the Bolivian (Inia geoffrensis boliviensis) subspecies as a full species, Inia boliviensis. In 2014, the population in the Araguaia-Tocantins basin was recognized to be an additional species, Inia araguaiaensis.[4]
