The understanding of species boundaries within the genus has changed dramatically during the last decade with the widespread usage of chromosomal and molecular data, resulting in an unstable taxonomy.
One of the issues recently raised, on the basis of a study of specimens from south central Brazil (Mato Grosso do Sul State), is the distinctiveness at the species level of T.
fosteri (with type locality in Paraguay), usually considered a synonym of T.
pachyurus.
Here we provide the first morphologic, karyotypic and molecular data for a series of Paraguayan specimens of Thrichomys aimed to resolve this taxonomic conundrum. Methodology: Thirty one specimens collected at five Paraguayan localities were morphologically assessed. Descriptive statistics for 20 cr...
