﻿AbstractBoana, the third largest genus ofHylinae, has cryptic morphological species. The potential applicability ofb-ﬁbrinogen intron 7 – FGBI7is explored to propose a robust phylogeny ofBoana. The phylogenetic potential ofFGBI7was evaluated using maximum parsimony, MrBayes, and maximum likelihood analysis. Comparison of polymorphic sites and topologies obtained with concatenated analysis ofFGBI7and other nuclear genes (CXCR4,CXCR4,RHO,SIAH1,TYR, and28S) allowed evaluation of the phylogenetic signal ofFGBI7. Mean evolutionary rates were calculated using the sequences of the mitochondrial genesND1andCYTBavailable forBoanain GenBank. Dating ofBoanaand some of its groups was performed using the RelTime method with secondary calibration.FGBI7analysis revealed high values at informative sites for parsimony. The absolute values of the mean evolutionary rate were higher for mitochondrial genes than forFGBI7. Dating of congruentBoanagroups forND1,CYTB, andFGBI7revealed closer values between mitochondrial genes and slightly different values from those ofFGBI7. Divergence times of basal groups tended to be overestimated whenmtDNAwas used and were more accurate whennDNAwas used. Although there is evidence of phylogenetic potential arising from concatenation of specific genes,FGBI7provides well-resolved independent gene trees. These results lead to a paradigm for linking data in phylogenomics that focuses on the uniqueness of species histories and ignores the multiplicities of individual gene histories.
