Yes. Notable Argentine reclassifications include the revalidation of the pouched lamprey, the merger of an allegedly extinct mouse opossum with a living species, and the recognition of new or restored armadillo, fish, bird, mammal, and fungus taxa. The strongest cases combine morphology with DNA or other integrative evidence; several bird names remain explicitly disputed, showing that taxonomy is a continuing process rather than a fixed catalogue.

The outsider edge of Argentine taxonomy is less a rejection of genetics than a challenge to premature certainty. Historical specimens, geographic variation, vocalizations, coloration, and changing species concepts can produce competing classifications. Bird proposals and the armadillo’s tangled nomenclature show how names may be elevated, merged, removed, or restored as new comparisons alter the case.
The status of Serpophaga munda has been contested, with authors variously treating it as a species, subspecies, or morph of S. subcristata.
Xolmis salinarum has alternated between species and subspecies treatment since its elevation in 1987.
The Dasypus mazzai case has involved competing interpretations as D. novemcinctus, D. yepesi, or a distinct taxon.
Geastrum argentinum was once treated as a synonym of G. fimbriatum but was later re-described as a valid species from Argentine material.
Pleistoanser bravardi was reinterpreted from a duck-like bird as a parrot related to Cyanoliseus, illustrating how fossil identifications can shift after specimen restudy.
