Resumen:
The family Rhinocryptidae comprises an assemblage of 12 genera and 55 species confined to the Neotropical region.Here we present the first morphology-based phylogenetic study of the Rhinocryptidae, using 90 anatomicalcharacters (62 osteological, 28 syringeal) scored for all genera of the family and representatives of all families of theinfraorder Furnariides. Parsimony analysis of this dataset recovered 7428 equally most-parsimonious trees. Thestrict consensus of those trees was completely resolved at the genus level, with the topology (Liosceles (Psilorhamphus((Eleoscytalopus + Merulaxis) (Acropternis ((Teledromas + Rhinocrypta) ((Pteroptochos + Scelorchilus) (Eugralla(Myornis + Scytalopus)))))))). The monophyly of the Rhinocryptidae as presently understood was recovered withstrong support [eight synapomorphies and Bremer support (BS) = 6). Strongly supported internal arrangementsincluded the basal position of the Amazonian genus Liosceles relative to the rest of the family (four synapomorphies,BS = 4), a clade containing Acropternis through Scytalopus (six synapomorphies, BS = 4), and other less inclusivenodes. The main points of congruence between the present morphological phylogeny and previous molecularphylogenetic work on the family were clades supported by six or more synapomorphies and Bremer values of 6?7:Eleoscytalopus + Merulaxis (eight synapomorphies, BS = 6), Scelorchilus + Pteroptochos (seven synapomorphies,BS = 7), Rhinocrypta + Teledromas (seven synapomorphies, BS = 7), and Eugralla + Myornis + Scytalopus (six synapomorphies,BS = 6). A classification derived from the morphological phylogeny is proposed, with new supragenerictaxa being named and diagnosed.
