In this study (review), we discuss the scientific literature investigating the reproductive behavior employed by Centridini males in nest aggregation and their important role in maintaining aggregation during generations. Centridini tribe is a Neotropical of oil-collecting bees, composed of only two well supported monophyletic genera of solitary bees Epicharis and Centris. These two genera have varied nesting habits, with some species forming large aggregations and pollinating from various species of angiosperms. We used Google Scholar, SciELO, and the Capes Periodical Portal with CAfe access Database to find peer-reviewed publications during May and July 2022. In addition, we use keywords directed to the topic and select only scientific articles from indexed periodicals. We found that few scientific articles are directed to studies of males in nest aggregates, and some characteristics of their reproductive behavior are described in research on nesting biology. Furthermore, with the philopatric characteristic of females for nesting, we suggest that the importance of males is underestimated and poorly understood for the maintenance of these populations. Finally, we reinforce the importance of research focused on male behavior, as well as population genetic studies to understand the real value of male dispersal in solitary bees, especially the Centrini tribe.
