The subgenus Micoureus (Didelphidae: Marmosa) in Paraguay: morphometrics, distributions, and habitat associations

From the journal Mammalia

Abstract

Two species of Marmosa (Micoureus) have been documented from Paraguay. Based, in part, on a recently collected series of Marmosa constantiae, we review the morphometric relationships, distributions, and habitat associations of the two species in Paraguay. Marmosa paraguayana is documented from nine localities, all in eastern Paraguay, in the region originally covered by Upper Paraná Atlantic Forest (UPAF). Marmosa constantiae is documented from five localities, all of which are forested areas (generally gallery forest) embedded within Cerrado patches bordering UPAF, or within the Humid Chaco or Dry Chaco ecoregions. Specimens of M. constantiae from the Dry Chaco locality Parque Nacional Defensores del Chaco are morphometrically distinct from both M. paraguayana and other M. constantiae specimens and may represent an unrecognized taxon.
