Genetics can provide invaluable tools for management and conservation of bee populations, which are declining worldwide. Among these tools, microsatellite are very useful molecular markers for population analyses. The aim of this study was to isolate and characterize microsatellites for Epicharis (Anepicharis) dejeanii and Epicharis ( Epicharis ) nigrita , two Neotropical species of solitary bees, both exhibiting the habit of nesting in aggregations. Microsatellite loci were identified from two enriched genomic libraries. The characterization and analysis of loci were carried out using 35 females of E. dejeanii and 34 of E. nigrita . In total, we report the development of 12 microsatellite loci for E. dejeanii and 13 for E. nigrita . For E . dejeanii , all loci were polymorphic, the number of alleles per locus ranged from 2 to 12, averaging 8.7 and, observed and expected heterozygosity were 0.485 (range 0.229–0.857) and 0.633 (range 0.288–0.843), respectively. For E. nigrita , only nine out of 13 loci amplified were polymorphic, the number of alleles per locus ranged from 2 to 12, averaging 5.5. For this species, the observed and expected heterozygosity were 0.440 (range 0.118–0.676) and 0.545 (range 0.167–0.814), respectively. Cross-amplification of primers was successful in other Centridini species. The two sets of loci described for E. dejeanii and E. nigrita species are polymorphic and informative and show promising applicability for both population genetic approaches and relatedness on these and other Centridini species.
