During a global survey of the diversity of vertebrates and their parasites including the Gobi and desert/steppe biomes ranging from south central to western Mongolia, we found metacestodes (larvae) of Echinococcus multilocularis (Leuckart 1863) in the liver of an individual vole (Microtus limnophilus Büchner 1889) collected in grassland habitat at Har Us Lake, southeast of Hovd, Mongolia. Positive identification of E. multilocularis from near Hovd was made via comparative cyst morphology, study of hooks from the rostellum derived from protoscolexes, and DNA sequencing of the COX1 mitochondrial gene extracted from tissue of the cysts frozen in the field. This report represents the first record of this species from an arvicolid intermediate host in Mongolia. This report also includes a second record from Bolivia of E. vogeli Rausch and Bernstein 1972 (confirmed by measurements of the hooks and cyst morphology) from the common intermediate host, Cuniculus paca Linnaeus 1758, collected in the Pilón Lajas Biosphere Reserve, Beni Department.
