The genetic variability of 66 colonies of Partamona helleri collected in five locations of Minas Gerais state was estimated using ten microsatellites loci. Low levels of polymorphism were detected, getting 40% of polymorphic loci and 1,5 alleles/Iocus. The expected average heterozygosity for all the analyzed colonies was 0.180 and the observed average heterozygosity was 0.107. The analyzed subpopulations were well structured, with significant genetic variation (FST = 0.552). The analysis of molecular variance (AMOVA) revealed that 81.23% of the total genetic variability is explained by variation among populations, what confirms the structure observed. The grouping analysis of the colonies, did not reveal the formation of groups corresponding to their geographic origin. However, when grouping colonies according to localities, it was verified that the population of Viçosa was more genetically different from the others, and that populations of São Miguel do Anta, Teixeiras and Porto Firme were closer to that collected in Rio Vermelho, than to population of Viçosa, although Rio Vermelho was geographically more distant. More detailed studies, analyzing a larger number of colonies and using microsatellites primers specific for P. helleri, must be carried out in order to supply more conclusive information about the genetic variability of these bees.
