SUMMARY:

The sting is a modification of the ovipositor, shared by all taxa of the Aculeata, which include ants, wasps and bees. Morphological studies involving descriptions of this structure are relatively frequent for certain taxa. However, the sting is still little explored in comparative studies, even with useful characters in taxonomic delimitations. To investigate the informative potential of this structure, we used bees from the Anthidiini tribe as a model. The objective of this work was to investigate the morphology of the sting of thistaxa, carrying out a comparative  morphological study to understand the evolution of this structure within the tribe and indicate new characters that help in generic delimitation. For this, females from 26 genera and 55 species of Anthidiini were analyzed, as well as females from other three tribes of Megachilinae. The morphological study demonstrated that there is a generic pattern for some of the sting structures. The use of these characters can help with generic delimitations in the current classifications of the tribe. Besides that, the data obtained confirm the importance of use of sting in comparative morphological studies involve the distinct lineage of Aculeata.
