Nomascus is the second-most speciose genus of the gibbon family, Hylobatidae. Originally, this genus was a subgenus of Hylobates, with all individuals considered to be one species, H. concolor.
Species within Nomascus are characterized by 52 chromosomes. Some species are all-black, some are a lighter beige or peach hue, with a distinct black tuft of crown fur, while others have notable, light-colored cheek “patches”. Nomascus is endemic from southern China ( Yunnan) to southern Vietnam, and can also be found on Hainan. Every species within this genus are either endangered or critically endangered; the Eastern black crested gibbon (Nomascus nasutus) has been deemed "the most-critically endangered ape species in the world".
