Collared titi least two species in this complex. But whether the Lucifer titi, "Cheracebus lucifer", or the Colombian black-handed titi, "Cheracebus medemi", are good species from this complex is in doubt. They are probably subspecies of "Cheracebus torquatus".

Five adults weighed an average of 1462 g (range 1410–1722 g) with a head-body length of around 290–390 mm and a tail length of about 350–400 mm.
