The genus Graff, 1896 encompasses 16 species, most of them found in Brazil. Herein two new species of this genus are described from remnants of moist forests, located in the states of Paraná and Santa Catarina, south Brazil. Both species resemble the type-species of the genus, , showing brownish dorsal surface covered by dark-brown flecks. However, regarding their anatomy, the new species differ from and other congeners by a long and horizontal disposed permanent papilla.
