Proceratophrys cururu, a species superficially similar to P. cristiceps and P goyana, is described as new from the Serra do Cip6, Minas Gerais, southeastern Brazil. The new species differs from both P cristiceps and P goyana by its more contrasting dorsal color pattern, larger and more heterogeneous dorsal tubercles, dorsal tubercular rows interrupted in the sacral region, and two to three large tubercles in the suprascapular region.
