We present three new records of C. hudsoni, a secretive and small-sized Amazonian species of frog, from the municipalities of Barcarena, Santa Bárbara, and Primavera, all in the state of Pará, Brazil. These records extend the known species distribution in 520 km account to the first geographical records from the Belém Area of Endemism (BAE), the most threatened region of the Amazon basin. The records have relevant implications for several aspects of the biology of Chiasmocleis, especially biogeography, taxonomy, and conservation.
