Like atlantic titis, they can reach a head trunk length of over 40 centimetres and a weight of up to 1.6 kilograms.

Their dense fur is predominantly grey or grey-brown in colour, the head and paws are black.

Coastal black-handed titis are found on the Brazilian Atlantic coast, their range includes the south of Bahia and the north of Espírito Santo.

The habitat of the Southern Bahia Jumping Monkey is located in one of the most densely populated regions of Brazil, and its range is correspondingly reduced and fragmented.

The main threat is the ongoing habitat destruction; the IUCN lists the species as "vulnerable".
