Tremacebus is an extinct genus of New World monkeys from the Early
Colhuehuapian in the SALMA classification). The type species
is T. harringtoni.
Tremacebus was about 1 metre (3.3 ft) in length, and would have
resembled a modern night monkey, to which it may have been related.
However, its eyes appear to have been smaller than the modern species,
CT scans of the cranium suggest a relatively small olfactory bulb and
poor sense of smell, compared with night monkeys. These features
suggest that it may not have been nocturnal.
Only a few fossils have been found, including a skull from the
Sarmiento Formation, Patagonia.
