Phylogenetic relationships among cryptic species of the Phyllotis xanthopygus complex (Rodentia, Cricetidae)

Abstract: The leaf‐eared mouse, Phyllotis xanthopygus (Waterhouse 1837) is a widely distributed sigmodontine rodent in South America, with populations ranging from central Peru to southern Argentina and Chile. Previous morphological and molecular contributions have suggested that P. xanthopygus represents a species complex. In order to characterize and disclose this cryptic species complex, we perform a molecular genetic/phylogenetic analysis of representative samples across its geographical distribution. Phylogenetic a… Show more

“…Several systematic studies, based both on morphological and molecular data, have contributed to clarifying most of the phylogenetic relationships, species boundaries and taxonomy among the species of this genus (e.g. Ferro et al., 2010; Jayat et al, 2007; Jayat et al., 2016; Steppan, 1995, 1998; Steppan et al., 2007; Pacheco et al., 2014; Rengifo & Pacheco, 2015, 2017; Ojeda et al., 2021). All these studies have substantially expanded our understanding of the species‐level taxonomy of the genus, but several uncertainties still remain, especially for populations representing the nominal forms described for central and southern Andean areas (Ojeda et al., 2021).…”

“…Across this 6,000 km range, populations assigned to P. xanthopygus are often the most common rodent species among small mammal assemblages (Steppan & Ramírez, 2015). Although this rodent shows an apparently continuous geographic distribution across the arid and semiarid Andean ecosystems, some geographically isolated populations occur in central Argentina, within temperate grassland environments (Ojeda et al., 2021; Steppan & Ramírez, 2015; Teta et al., 2018).…”
