Nomascus is the second most speciose genus within 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. Nomascus is found from southern China (Yunnan) to southern Vietnam, and also on Hainan Island. One of the genus' species, Nomascus nasutus, has been deemed "the most critically endangered ape species in the world" (Geissmann et al., 2000; 2003).
