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/critically endangered; the Eastern black crested gibbon (Nomascus nasutus) has been deemed "the most-critically endangered ape species in the world".
