Taxonomy of the San Martin titi monkey PDF Print E-mail

The taxonomy of the genus Callicebus has been reviewed several times. Currently some 30 species are recognized.

Callicebus oenanthe is probably closely related to the titi monkey species that can be found in Bolivia, being C. ollalae, C. modestus and C. donacophilus, and C. pallescens distributed in Paraguay and Brazil. It is important to notice that the latter four species have a continuous distribution, while there is a gap of more than 1000 kms with the distribution range of C. oenanthe. Genetic studies are urgently needed to understand the relationship between the different species, but we can assume that C. oenanthe is genetically the most unique species of all titi monkeys.

The first name that was used for this species was the “Isabelline titi monkey”. Later it was commonly known as the Rio Mayo titi monkey or the Andean titi monkey. However, as the research of Proyecto Mono Tocón showed that the species is not restricted to the Rio Mayo Valley, nor lives in the Andean mountains, we prefer to call it the San Martin titi monkey. The species is endemic to the San Martin Region of north-eastern Peru.

The San Martin titi monkey is locally known as the “mono tocón”, or in the native Awajun language as the “sugkamat”.

For more information on the taxonomy of the Callicebus genus we would like to refer to the Callicebus Database Project.
