Isolation and cross-species characterization of polymorphic microsatellites for the orchid bee Eulaema meriana (Hymenoptera: Apidae: Euglossini)

We describe and characterize eight polymorphic microsatellite loci for the orchid bee species Eulaema meriana, an abundant species and important pollinator in wet lowland forests in tropical America. We also tested the cross-species amplification of these microsatellite loci in seven other species of the genus Eulaema. For E. meriana, number of alleles per locus ranged from four to nine and expected heterozygosity ranged from 0.377 to 0.854. Seven out of the eight loci described amplified in all seven other Eulaema species. These microsatellite loci will be of practical use for population structure, mating system and inbreeding studies in euglossine bees.
