Background/Objectives: A striking feature of the karyotypes stingless bees is large amount heterochromatin present in most species. Cytogenomic studies performed some Meliponini species have suggested that evolutionary events related to diversification and amplification satellite DNA families may reflect structuring phylogenetic clades this tribe. In study, we a genomic analysis Frieseomelitta varia characterize different satDNA its genome. We also investigated presence abundant family F. own chromosomes, two other species, genera encompassing three main Neotropical Meliponini, according available molecular phylogeny. Methods: Genomic analyses were using RepeatExplorer2 on Galaxy platform, chromosomal investigations conducted fluorescent situ hybridization. Results: Seven recovered, which together totaled an abundance 11.223% analyzed fraction. The family, FvarSat01-306, predominates repetitive fraction (representing around 89%) was recently amplified homogenized almost all varia. addition, data revealed unprecedented sharing centromeric/pericentromeric among genera, with independent amplifications loss sequence taxa. Conclusions: One makes up shared Meliponini.
