Atlantic Titi (Callicebus personatus)
Callicebus is a genus of titis.
Historically, titis were monogeneric, comprising only the genus Callicebus Thomas, 1903. 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; Cheracebus 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.
