Mazama simplicicornis argentina
is the name given to the description of a gray brocket collected in
1919 by Lönnberg in the central Chaco of Argentina. Subsequent authors,
based on morphological similarities, considered this name as a synonym
of the species Subulo gouazoubira
Fischer, 1814 from Paraguay. In the absence of genetic analyses to
compare the Argentinian and Paraguayan gray brockets, we aimed to
clarify the taxonomy of M. simplicicornis argentina
through an integrative assessment using morphological, cytogenetical,
and molecular data from its holotype and a current topotype.
Qualitative skull features and cranio-morphometric results of M. simplicicornis argentina showed a great similarity with the S. gouazoubira neotype characters. The diploid chromosome number of M. simplicicornis argentina topotype correspond to the karyotypical pattern of S. gouazoubira with
2n = 70 and FN = 70, showing a great similarity in all classic and
molecular cytogenetic results and evidencing the homologies between
karyotypes. The phylogenetic analysis of mitochondrial genes used in
this study (concatenated partial ND5 and Cytb gene) allocated the M. simplicicornis argentina specimens in the monophyletic clade of S. gouazoubira
with 100% of branch value. These results evidenced that there is no
discontinuity between the Argentinian and Paraguayan gray brockets,
therefore, the individuals originally described as M. simplicicornis argentina should be recognize as S. gouazoubira species.
Key words: Animal cytogenetic, Cervidae, Gray brocket, Mitochondrial DNA, Morphology.
