We describe a new small species of Scinax from the rain forests on the interfluve between Purus and Madeira Rivers, Brazilian Amazonia. The new species is diagnosed by snout-vent length 20.2-22.5 mm in males; a yellowish-bronze dorsum showing small spots along the body and limbs; a red stripe horizontally extended on the medial portion of the iris; posterior surface of thigh brown, in both live and preserved specimens. The advertisement call consists of two types: type A represents a series of multipulsed notes (note duration 0.097-0.115 sec, dominant frequency 2,541-3,015 Hz); type B consists of a single tonal note (note duration 0.015-019 sec, dominant frequency 2,584-2,950 Hz).
