Abstract
Thirty-three species representing all 14 genera of the South American rodent tribe Phyllotini and 5 problematic genera are surveyed for 96 multistate and binary dental, cranial, skeletal, external, and male reproductive tract characters. Wagner parsimony analysis confirmsCalomys as the most basal phyllotine genus, and as currently constituted it is likely paraphyletic. The results are consistent with the exclusion ofPseudoryzomys from the phyllotines and the separation ofReithrodon andNeotomys fromHolochilus at the tribal level. Several highly differentiated generic groups that include a radiation of altiplano endemics centered onAuliscomys and the largely southern Andean/PatagonianReithrodon group appear to form a clade. AGraomys generic group that includesAndalgalomys andEligmodontia is also apparent, but its relationships to other phyllotines are obscured by poorly resolved internal nodes in the more species-rich and probably paraphyletic genusPhyllotis. The significance and consequences of more intensive taxonomic sampling are discussed. The taxonomic consequences of the phylogeny are presented.
