Taxonomic novelties in Didelphis albiventris Lund, 1840 and revalidation of Didelphis poecilotis A. Wagner, 1842 (Didelphimorphia, Didelphidae)

In a recent article, we showed that <em>Didelphis albiventris</em> might be separated into two taxonomic entities. Molecular evidence, environmental niche modeling, and qualitative morphological characters indicate that there are two clearly separated groups, one including specimens from central and northern Brazil, and the other comprising Argentina, Uruguay, Paraguay, Bolivia, and southern Brazil. In this contribution, we formalize the splitting of the white-eared opossum into two species, <em>D. albiventris</em> for the northern group and <em>D. poecilotis</em> for the southern group, and we provide an emended diagnosis for both species and information on type specimens and distribution. <hr /> <strong>Novedades taxonómicas en <em>Didelphis albiventris</em> Lund, 1840 y revalidación de <em>Didelphis poecilotis</em> A.

Abstract

In a recent article, we showed that <em>Didelphis albiventris</em> might be separated into two taxonomic entities. Molecular evidence, environmental niche modeling, and qualitative morphological characters indicate that there are two clearly separated groups, one including specimens from central and northern Brazil, and the other comprising Argentina, Uruguay, Paraguay, Bolivia, and southern Brazil. In this contribution, we formalize the splitting of the white-eared opossum into two species, <em>D. albiventris</em> for the northern group and <em>D. poecilotis</em> for the southern group, and we provide an emended diagnosis for both species and information on type specimens and distribution. <hr /> <strong>Novedades taxonómicas en <em>Didelphis albiventris</em> Lund, 1840 y revalidación de <em>Didelphis poecilotis</em> A.
