title: The banded karyotypes of Macaca fuscata compared with Cercocebus aterrimus.
abstract: The karyotypes of Macaca fuscata and Cercocebus aterrimus are compared after G, C and AgNOR banding. Although it is often assumed that the 42-chromosome monkeys (species of the genera Macaca, Papio, and Cercocebus) are identical at the chromosomal level, a number of clear and consistent differences between the karyotypes of these two taxa are described. These differences include one pericentric inversion and differences in staining intensity, particularly in centromeric and pericentromeric areas. It is probable that high resolution chromosome techniques could reveal more differences between taxa in the 42-chromosome group than are now believed to exist. It is therefore probable that karyological data could provide insight into the phylogenetic relationships in this group of Old World monkeys.
