Ischnocnema is a genus of frogs from east Brazil and northeast Argentina.[1][2][3] They comprise the former Eleutherodactylus from this region,[4] but they are closer to Brachycephalus than the "true" Eleutherodactylus. Consequently, they are now placed in their own genus Ischnocnema in the family Brachycephalidae.[1][2][3]


There are 33 species:[1][2]
