Three distinct and independent molecular-based species delimitation analyses were performed among the species and populations included within the    Australoheros   autrani    group, based on sequences of the mitochondrial gene Cytochrome b: a tree-based method proposed by Wiens and Penkrot (WP), a Character-based DNA Barcoding ( CBB ) and coalescent species delimitation method termed the Bayesian Implementation of the Poisson tree processes ( bPTP ). The congruence of WP and  CBB  delimited 11 independent lineages (species), while the  bPTP  delimited just nine lineages. We did not favour any of the methods, and we considered the possibility of two slightly variant scenarios. A time-calibrated phylogenetic analysis is proposed based on the predominant congruence of the results of these three species delimitation methods herein applied. The monophyly of the    A.   autrani    species group was highly supported with maximum node support value and diagnosed by 11 nucleotide substitutions. The sister clade of the    A.   autrani    species group is the clade comprising    A.    sp. Timbé do Sul and    A.   minuano   . The phylogenetic analysis supports three main clades within the    A.   autrani    species group, supported by maximum node support value, with the Southern Mata Atlântica clade as the most basal clade. Divergence time estimates indicate that the diversification of the    Australoheros    originated during the early Neogene, but only in the late Neogene did the processes of diversification in the southeast and north regions occur. Diversification within the    Australoheros   autrani    species group occurred synchronically for the three main clades during the beginning of the Quaternary. It is demonstrated that molecular characters are valuable tools for species recognition, particularly in speciose groups with inconspicuous or difficult to record morphological characters. The resulting phylogeny of the    Australoheros   autrani    group is highly compatible with the geological and biogeographic scenarios proposed for the Neogene and Quarternary shaping of the extant river basins of eastern Brazil. Despite the origin of the    A.   autrani    group being dated to the late Miocene, species level diversification occurred in the Pleistocene and was probably driven by headwater capture events and sea-level fluctuations.
