Unduavi gracile opossum

The Unduavi gracile opossum (Cryptonanus unduaviensis) is a species of opossum in the family Didelphidae. It is native to northern Bolivia, where it has been found in seasonally flooded grassland.[1] Some of the specimens recognized by Voss et al. as belonging to this species were previously classified as the unduaviensis or buenavistae subspecies of Gracilinanus agilis.[2][3]
