The Proceratophrys bigibbosa species group comprises four species and is the only group likely to be monophyletic within the genus. I describe the tadpole of P. bigibbosa and its buccopharyngeal morphology. Comparisons among Proceratophrys larvae in the light of a phylogenetic tree suggest that a conical vent tube, tail fin originating in the body/tail junction, large A2 gap, and trapezoid median ridge may represent putative synapomorphies for the P. bigibbosa group.
