【 摘 要 】

Cephalotrigona femorata (Smith, 1854) was submitted to cytogenetic techniques to study and describe its karyotype. Conventional staining allowed the counting (2n=34) and observation of chromosome morphology. The amount and distribution of heterochromatin in this species was different from Cephalotrigona capitata(Smith, 1854) , another species of the genus already analyzed. Our results indicate that heterochromatin a potential marker for the genus, at least for the species found in Brazil. This region was marked by DAPI, revealing a high content of A:T. The CMA3 marked two pairs, and it seems to be  polymorphic in one pair.
