Titi to the great diversity found across titi monkey species, a new genus-level taxonomy was recently proposed that recognises three genera within the subfamily Callicebinae; "Cheracebus" Byrne et al. (2016) for the species of the "torquatus" group (Widow titis); "Callicebus" Thomas, 1903, for species of the Atlantic Forest "personatus" group; and "Plecturocebus" Byrne et al. (2016) for the Amazonian and Chaco titis of the "moloch" and "donacophilus" groups. Titi The titis, or titi monkeys, are the New World monkeys of the subfamily Callicebinae, which contains three extant genera, "Cheracebus", "Callicebus", and "Plecturocebus." This subfamily also contains the extinct genera "Xenothrix, Antillothrix",
Ornate titi The ornate titi is monogamous, and their upbringing is entirely paternal, only ever being passed to the mother to be fed. with the birth season being from December to March, with the smallest infants being born in December to January. The average gestation period for an ornate titi is 128 days (4.2) months, and there have been observations that, during lactation, female titis tend to increase the amount of protein in their diet (Primarily by eating more insects). Some conservation efforts within Colombia have been made, since the species occurs in La Macarena National Park and Tinigua National Park, and
