Resumen:
Furnariidae is a Neotropical group of birds with dull coloration and adapted to all biomes. There is
great controversy about the systematic position of Furnariidae species, genera and subfamilies.
The general objective of this research was to study the variation of morphological, behavioral and
molecular characters of furnariids, in order to obtain a phylogeny which synthesizes the
relationships between the main taxa that compose this family. For this purpose, we have made a
detailed anatomical comparative description of their osteology (74 characters) and syringeal
morphology (26 characters); and we have also added molecular (7760 sites) and nest (22
characters) data for the main genera. In this way, this study comprises one of the largest sets of
characters of a very diverse Neotropical family of birds. The total evidence cladistic analysis
showed that dendrocolaptids should be considered together with furnariids in a monophyletic
group. Dendrocolaptidae appeared as paraphyletic because of the position of the genus
Sittasomus (Dendrocolaptidae) which was placed as the sister group of the monophyletic group
Furnariidae. On the other hand, genus Geositta (Furnariidae) was not placed as an outgroup of
Dendrocolaptidae as was suggested by previous studies. None of the subfamilies traditionally
recognized were recovered. Synallaxis, Asthenes, Phacellodomus, Geositta and Cinclodes were
showed as monophyletic groups in the analyses of the studied species, but Upucerthia,(Dendrocolaptidae) which was placed as the sister group of the monophyletic group
Furnariidae. On the other hand, genus Geositta (Furnariidae) was not placed as an outgroup of
Dendrocolaptidae as was suggested by previous studies. None of the subfamilies traditionally
recognized were recovered. Synallaxis, Asthenes, Phacellodomus, Geositta and Cinclodes were

Automolus and Phylidor appeared as poliphyletic or paraphyletic groups. Moreover, each pair of
monotipic genera Phleocryptes-Spartonoica, Anumbius-Coryphistera, and Pygarrhichas-Xenopsand Phylidor appeared as poliphyletic or paraphyletic groups. Moreover, each pair of
monotipic genera Phleocryptes-Spartonoica, Anumbius-Coryphistera, and Pygarrhichas-XenopsPhleocryptes-Spartonoica, Anumbius-Coryphistera, and Pygarrhichas-Xenops
were placed as being sister species. Regarding the evolution of characters, the plesiomorphic
state of the scored morphological characters were the ones we have found in dendrocolaptids, in
contrast with what would have happened if those characters were mapped in the previous
existing molecular phylogenies.
