Collared Titi (Cheracebus torquatus)
Cheracebus is a genus of titis.
Historically, titis were monogeneric, comprising only the genus Callicebus. Owing 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 for the species of the torquatus group (Widow titis); Plecturocebus for the Amazonian and Chaco titis of the moloch and donacophilus groups; and Callicebus, for species of the Atlantic Forest personatus group.
