This chapter describes a new species of Thomasomys from the eastern slopes of the central Bolivian Andes. It observes that this is a medium-size long-tailed rodent phenetically similar in external and cranial features to Thomasomys notatus, although genetically it appears most closely related to species in the Thomasomys oreas complex. The chapter notes that phylogenetic analyses of morphological and molecular data indicate that the new species presents a unique combination of characters. It further notes that the new taxon inhabits the upper montane rain forest and appears to be arboreal; it is known only from the type locality.
