SUMMARY:

The Caatinga Domain is the largest continuous área of seasonally dry forests globally, with a distinct biota adatpted to Strong climatic seasonality. It’s plants are major pollinated by bees, that in this semiarid ecosystem remains with some gaps of diversity knowledge lacking. In this study, we provide a updated synthesis of bee diversity in the Caatinga by compiling data from published studies from 2000 to 2025 with information
the earliest bee checklist. We conducted a systematic literature review arranging taxonomic, geographic and functional data from several publications. Then, the resulting dataset includes 1.386 occurrences representing 255 species distributed across 96 genera, 36 tribes. Apinae was the richest subfamily, followed by Megachilinae and Halictinae. We then observed that sampling effort was highly uneven between the dry areas and the humid areas across the domain. We find that non-eusocial bees and generalists species predominated. Nesting strategies were mainly subterranean, with soil being the most frequent nesting substrate used, whereas in humid areas showed higher proportion of above ground and wood associated nesting species. In adition, a large number of species were recorded only once, indicating that some species may be neglected by insuficient spatial coverage. Overall, this study reveals a taxonomically rich and functionally structured bee fauna, but otherwise, this knowledge is heavilly shaped by spatial sampling biases, highlightning the need for systematic inventories in the less studied Neotropical dry forests.
