Karyotype description of Cephalotrigona femorata Smith (Hymenoptera: Apidae) and the C-banding pattern as a specific marker for Cephalotrigona

<em>Cephalotrigona femorata</em><span> (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 </span><em>Cephalotrigona capitata </em>(Smith, 1854)<span>, 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 CMA</span>₃<span> marked two pairs, and it seems to be polymorphic in one pair.</span>
