    Phylogenetic relationships inside the tribe Sciurini produce conflict between older morphological research and modern molecular studies. We provided a detailed phylogenetic analysis by incorporating eight loci and various methods of data processing. We used prevailing and user-friendly software packages (Geneious, BioEdit, MrBayes, ModelTest). Evolutionary history of Sciurini squirrels was examined by means of Bayesian inference of concatenated data set and six supertree construction methods. The concatenated data and supertrees generated by SuperTriplets, modified MinCut, standard MRP and veto supertree (without source tree correction) yielded similar results with taxa grouped according to their zoogeographic distribution. The genus Tamiasciurus formed a separate evolutionary lineage at the base of our trees and the other taxa gradually diverged into Palaearctic/Indomalayan, Nearctic and Neotropical groups. The other used methods, MinCut, Purvis-MRP and veto (with source tree correction) showed deviations from this pattern.
