| Eight species of Rhinocryptidae are recognized from Chile. Moreover, morphological, ecological and behavioral differences among two lineages of _Scytalopus_ and two species of _Pteroptochos_ are unclear. According to our results, there are no decisive criteria differentiating among subspecific sister taxa of _Scelorchilus albicollis_, _S. rubecula_ and _Pteroptochos megapodius_. Here we discuss the speciation of the chilean Rhinocryptidae based in their behaviour. We propose a new methodology based on ecological and behavioural patterns in order to understand the concept of speciation in this group of birds.

| The current classification of the chilean representatives of the passerine family Rhinocryptidae includes eight species. Three of them contain subspecies that don’t exhibit clear differences. Moreover, differences among two lineages of _Scytalopus_ genera and two species of _Pteroptochos_ are very scarce. We propose a new methodology based on ecological and behavioural patterns in order to understand the concept of speciation in this group of birds. According to our results, we postulate that there is not a cut criteria to establish differences among three sister lineages of current classification. This way the methodology developed by us does not allow to establish divergence for a given common ancestor. Our methodology allows to establish... |

According to our results, there are no decisive criteria differentiating among subspecific sister taxa of Scelorchilus albicollis, S.rubecula and Pteroptochos megapodius. Here we discuss the speciation of the chilean Rhinocryptidae based in their behaviour and we carried out an integrated analysis with specie outgroup Cinclodes oustaleti (Furnariidae). We propose a new methodology based on ecological and behavioural patterns in order to understand the concept of speciation in this group of birds.
