Discussion: This genus will have to be renamed and redefined, as Bunopithecus sericus is outside the modern gibbon clade and the Hoolock gibbon does not belong to the same genus (Groves, 2001 c); this was the reason why Groves (2001 c) did not take the step of elevating the subgenera of Hylobates to generic rank.
