LAGOTHRIX LUGENS PHENOTYPES DO NOT DEFINE A COHERENT TAXON

Increased use of the phylogenetic species concept in primatology has provoked several researchers in Colombia to examine the systematics of various taxonomic groups from the viewpoint of phenotype and genetics. The application of operational aspects of the phylogenetic species concept has often ignored the use of biological characters that might clarify a group´s systematics. Based on the study of more than 200 Lagothrix skins of both lagothricha and lugens, I point out the lack of sharp phenotypic distinctions between Lagothrix lagothricha and Lagothrix lugens and I further illustrate the lack of a clear definition of lugens, which is made up of numerous phenotypes. Based on phenotypes, I suggest the possibility of dividing lugens into two taxa, and I illustrate that this does not support the recognition of Lagothrix lugens as a coherent species, based on current knowledge and revisions of Fooden (1963) and Groves (2001).
