A new species and genus of digenetic trematode of the family Dicrocoeliidae is described from 2 species of grass mice, Akodon fumeus and Akodon mimus, both collected from an isolated area in the eastern part of the Andes mountains or Yungas of Bolivia. This species differs from all known dicrocoeliids in the unique disposition of the vitelline fields, the much less extensive uterus through the body of the worm (extending posteriad only just past the midline), and cecal branches that are generally conspicuous and lined with a thick layer of glandular epithelial tissue.
