Titi
The
titis, or
titi monkeys, are the New World monkeys of the genus
Callicebus. They are the only extant members of the
Callicebinae subfamily, which also contains the extinct genera
Xenothrix, Antillothrix,
Paralouatta, Carlocebus, Lagonimico, and possibly also
Tremacebus. Titis live in South America, from Colombia to Brazil, Peru and north Paraguay. Depending on species, titis have a head and body length of 23–46 centimetres, and a tail, which is longer than the head and body, of 26–56 centimetres. The different titi species vary substantially in coloring, but resemble each other in most other physical ways. They have long, soft fur, and it is usually reddish, brownish, grayish or blackish, and in most species the underside is lighter or more rufescent than the upperside. Some species have contrasting blackish or whitish foreheads, while all members of the subgenus
Torquatus have a white half-collar. The tail is always furry and is not prehensile. Diurnal and arboreal, titis predominantly prefer dense forests near water. They easily jump from branch to branch, earning them their German name,
Springaffen.
