Morphological analysis of new Dryas Monkey specimens from the Central Congo Basin: Taxonomic considerations and an emended diagnosis.

In addition to pelage-based evidence, direct osteological evidence suggests "C. salongo" is a junior synonym of C. dryas. Combined with molecular analyses suggesting C. dryas is most closely related to Chlorocebus spp., we emend the species diagnosis and support its transfer to Chlorocebus or possibly a new genus to reflect its distinctiveness.
