“Nomascus is the second most speciose genus of gibbons (family Hylobatidae). Originally this genus was a subgenus of Hylobates, and all individuals were considered one species, Hylobates concolor. Species within Nomascus are characterized by 52 chromosomes. Some species are all black, some light with a distinct black tuft of crown fur, and some by distinct, light-colored cheek patches.
