Santarém Marmoset
Mico humeralifer
French: Quistiti a camail / German: Weil 3schulter-Seidenaffchen / Spanish: Titi deSantarém Other common names: Black-and-white Tassel-ear Marmoset, Tassel-ear Marmoset
Taxonomy. [acchus humeralifer E. Geoffroy Saint-Hilaire, 1812,
Brazil. Restricted by P. Hershkovitz in 1958 to Paricatuba, left bank near the mouth of the Rio Tapajos.
A. Humboldt is often credited in various ways with the name of this species, but E. Geoffroy Saint-Hilaire is the rightful authority. Humboldt in 1812 (dated 1811 but actually published a year later) credited Geoffroy Saint-Hilaire for his 1812 publication in Tome 19 of Annales du Museum d’Histoire Naturelle, where this species’ name first appeared. Humboldt’s nomenclatural act was a “name combination” in which he combined the name given by Geoffroy Saint-Hilaire with the genus Simia. A pale orange-brown marmoset formerly in the collection of the Belém Primate Center but otherwise very similar to M. humeralifer in fur color and pattern was obtained from the Rio Arapiuns in the northern part of the distribution. It was believed to be merely a chromogenic anomaly. Monotypic.
Distribution. Brazilian Amazon, S of the Rio Amazonas between the Rio Maués and probably its tributary the Rio Parauari in the W, and the Rio Tapajos in the E; the S limit is not known but may be in the region of the Rio Parauari.
Descriptive notes. Head-body 18-21 cm, tail 31-33 cm; weight mean c.475 g (males, n = 15) and ¢.472 + 26 g (females, n = 13). The dorsum of the Santarém Marmosetis black with white flecks, giving an overall marbled impression. The underside is sparsely furred with orange, and shoulders, arms, and crown are gray-brown to white. There is a white thigh stripe, hindlegs are brownish-black, and the tail is black with a suggestion of narrow silvery-white rings. Fronts of the crown and forehead are blackish, with a zone extending down the cheeks and expanding across the nose and jaw angles; sides of the crown have short, silvery hairs. The face is pigmented (yellow-brown), and there are long silvery-gray ear tufts that hang from the rims in the form of tassels and are continuous with the mantle hairs.
Habitat. Secondary lowland rainforest. The Santarém Marmoset prefers dense, viny vegetation and river edges. Observations in the Amazonia National Park, Para State, noted its presence mostly in secondary growth forest and not at all in flooded forest.
Food and Feeding. The Santarém Marmoset eats small fruits, nectar, gums, and small animal prey.
Breeding. Gestation is evidently less than 131 days, based on an interbirth interval in captivity of this duration. Weights of captive neonates are 33-37 g. Young feed independently by the end of three months, and reach adult weight and size at 9-10 months.
Activity patterns. There is no information available for this species.
Movements, Home range and Social organization. There is no information available for this species.
Status and Conservation. CITES Appendix II. Classified as Data Deficient on The [UCN Red List. Precise information on the conservation status of the Santarém Marmoset remains scant although it is thought to be threatened by development along the Trans-Amazonian Highway, which has opened up its previously inaccessible habitats to exploitation. It occurs in Amazonia National Park.
