'''''Callicebus''''' is a genus of [[monkey]]s known as [[titi monkey]]s.

Historically, titis were monogeneric, comprising only the genus ''Callicebus'' <small>Thomas, 1903</small>. 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]]'' <small>Byrne et al., 2016</small> for the species of the ''torquatus'' group (Widow titis); ''[[Plecturocebus]]'' <small>Byrne et al., 2016</small> for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; and ''Callicebus'' <small>Thomas, 1903</small> ''sensu stricto'', for species of the Atlantic Forest ''personatus'' group.<ref name=byrne2016>{{Cite journal|last1=Byrne|first1=Hazel|last2=Rylands|first2=Anthony B.|last3=Carneiro|first3=Jeferson C.|last4=Alfaro|first4=Jessica W.

In 2014, a previously unknown orange ''Callicebus'' was spotted in the Peruvian Amazon; it has not been determined whether this constitutes a color variant or a new species.<ref>{{cite web |last1=Vriesendorp |first1=Corine |title=Possible New Primate Discovered in Peru |url=https://www.fieldmuseum.org/blog/possible-new-primate-discovered-peru |publisher=Field Museum of Natural History |access-date=6 February 2022 |date=27 March 2015}}</ref>
