Abstract
Euglossinae represent an exclusively neotropical bee group, the cytogenetics of which is poorly known. We have studied ten specimens of Eufriesea violacea, nine males (K = 15 M) and one female (2K = 30 M). C-banding revealed constitutive heterochromatin throughout the extension of the long arm of 13 chromosome pairs. The end of the long arm had a lighter region in two chromosome pairs. The proximal region of the centromere of the short arm of all chromosomes was also heterochromatic. G-banding revealed three to four positive bands in both the heterochromatic and euchromatic regions of most chromosomes. The small number of G bands per chromosome can perhaps be explained by the structural arrangement of chromatin and they do not need to correspond to chromomeric regions.
