dc.description.resumoRapid loss of genetic diversity among eusocial bees, and extinction of their local population has become a major world concern. Populations of M. quadrifasciatahave increasingly declined due to predatory extractivism and destruction of their habitat. Knowledge of their local population could give insights on the strategies for monitoring and conservation of this species. In this study, initially, 14 colonies from the northern limit of the northeastern sandbank of the Atlantic Forest were analysed employing geometric morphometrics techniques. Then the cytochrome b gene sequences and ISSR primers were utilized for molecular analysis of these colonies and the results were compared with 15 M. quadrifasciata colonies found in the semiarid Caatinga region. The morphometrics and the molecular analysis suggested the formation of disjunct populations between the studied geographical zones. All the 14 colonies analysed from the São Francisco river region were found on the Southern margin of the São Francisco river and they all belonged to one single haplotype. No colonies were found on the Northern bank of the river. We suggest that the São Francisco river is an effective geographical barrier for the distribution of this species and propose an urgent need for the development of a conservation program for the population of M. quadrifasciataas it represents a unique haplotype in the region. Also their nesting habit exclusively in the diseased coconut trees which probably will be replaced by new trees, create the risk of population extinction due to the lack of nesting site.pt_BR
