Revalidation of (Illiger 1815) (Artiodactyla: Cervidae) as a Distinct Species out of the Complex (Erxleben 1777).

The red brocket deer Erxleben, 1777 is considered a polyphyletic complex of cryptic species with wide chromosomal divergence. Evidence indicates that the observed chromosomal divergences result in reproductive isolation. The description of a neotype for allowed its genetic characterization and represented a comparative basis to resolve the taxonomic uncertainties of the group.
