Argenteohyla

Argenteohyla siemersi, commonly known as red-spotted Argentina frog, is a species of frog in the family Hylidae. It is monotypic within the genus Argenteohyla.
It is found in the catchment of Paraná River in Argentina and Paraguay and in the southern coast of Uruguay.
There are two subspecies that might be distinct species: "Argenteohyla siemersi siemersi" and "Argenteohyla siemersi pederseni" . "A. s. pederseni" occurs in leaf axils of terrestrial "Aechmea" bromeliads in gallery forests along main river systems. It reproduces in temporary pools close to the bromeliads. The nominal subspecies occurs and reproduces in wetlands and the delta of Río Paraná. This rare frog is threatened by habitat loss.
