Scientific Name:

Xenothrix mcgregori

Species Authority:

Williams & Koopman, 1952

Common Name/s:

English

–

Jamaican Monkey

Taxonomic Notes:

This species has occasionally been included in its own family Xenothricidae (e.g., Hershkovitz 1974, MacPhee and Fleagle 1991), but most recently has been included in the tribe Xenotrichini in the family Pitheciidae (MacPhee and Horovitz 2004).

Assessment Information [top]

Red List Category & Criteria:	Extinct ver 3.1
Year Published:	2008
Assessor/s:	MacPhee, R. & Hoffmann, M.
Reviewer/s:	Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Justification: Listed as Extinct as this species is known only from fossil materials on Jamaica where it is believed to have survived until some time after 1700.

Geographic Range [top]

Range Description:	Originally known only from subfossil remains uncovered at Long Mile Cave in Jamaica, but additional cranial and postcranial material attributed to Xenothrix has since been recovered from elsewhere on Jamaica (MacPhee and Fleagle 1991, MacPhee and Horovitz 2004).
Countries:	Regionally extinct: Jamaica

Population:

Extinct. It is believed to have survived until after 1500, perhaps until some time after 1700 (MacPhee and Fleming 1999).

Habitat and Ecology [top]

Habitat and Ecology:	Xenothrix is known only as a fossil taxon. It has traditionally been regarded as a frugivore. Several features of the known limb skeleton suggest a slow quadrupedal locomotor style that has no evident counterpart among extant platyrrhines, but was possibly somewhat convergent on sloths (MacPhee and Fleagle 1991).
Systems:	Terrestrial
