Microsatellite loci for the carpenter bee Xylocopa frontalis (Apidae, Xylocopini)

Conservation Genetics Resources, 2011
In the present study, a microsatellite-enriched genomic library was constructed and primers for 14 microsatellite loci were designed for Xylocopafrontalis. Twenty unrelated individuals were screened. All loci were polymorphic and the number of alleles per locus ranged from 6 to 17 (x = 10.43).

Comparative morphology of the mesosomal ‘gland’ in male large carpenter bees (Apidae: Xylocopini)

Biological Journal of the Linnean Society, 1994
The gross morphology of the reservoir of the mesosomal gland of male large carpenter bees (tribe Xylocopini) was examined in 46 taxa (species and subspecies) in the three genera of the tribe. Males of all but six species of Xylocopa examined possess a cuticle-lined invagination that originates along the suture between the metanotum and propodeum.
