We describe a new species of the hylid frog genus Dendropsophus from Amazonian Ecuador. The new species, Dendropsophus shiwiarum sp. nov., appears to be part of the D. microcephalus species group. Dendropsophus shiwiarum differs from its congeners by a combination of: (1) tympanic membrane non-differentiated and annulus evident only ventrally, (2) disc of Finger III and Toe IV with pointed tip, (3) dorsal surfaces of digital discs with a conical tubercle as result of projection of distal phalanx, and (4) small size (SVL < 19 mm). The new species is morphologically most similar to Dendropsophus riveroi. Examination of the type material of the latter suggests that some Ecuadorian populations reported as D. riveroi were misidentified and in fact belong to D. shiwiarum sp. nov.
