Resumo
ObjectivesThe little known guenon Cercopithecus dryas has a controversial taxonomic history with some recognizing two taxa (C. dryas and C. salongo) instead of one. New adult specimens from the TL2 region of the central Congo Basin allow further assessment of C. dryas morphology and, along with CT scans of the juvenile holotype, provide ontogenetically stable comparisons across all C. dryas and 'C. salongo' specimens for the first time.Materials and MethodsThe skins and skulls of two newly acquired C. dryas specimens, male YPM MAM 16890 and female YPM MAM 17066, were compared to previously described C. dryas and 'C. salongo' specimens, along with a broader guenon comparative sample (cranial sample n = 146, dental sample n = 102). Qualitative and quantitative assessments were made on the basis of commonly noted pelage features as well as craniodental characters in the form of shape ratios and multivariate discriminant analyses.ResultsAll C. dryas specimens, including the TL2 adults, are comparatively small in overall cranial size, have relatively small I1s, and display tall molar cusps; these osteological characters, along with pelage features, are shared with known 'C. salongo' specimens. Discriminant analyses of dental features separate C. dryas/salongo specimens from all other guenons.DiscussionIn 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.
