On the occurrence of Hemiphractus scutatus (Spix, 1824) (Anura: Hemiphractidae) in eastern Amazonia
Hemiphractus Wagler, 1828 is part of Hemiphractidae Peters, 1862, a family that harbors species of frogs characterized by the deposition of eggs on the females' dorsum. Both the genus Hemiphractus and the species Hemiphractus scutatus (Spix, 1824) are only known to the Andean mountain range and west...
