What is "pileated gibbon"

n. (Hylobates pileatus), a primate in the Hylobatidae or gibbon family

The pileated gibbon (Hylobates pileatus) is a primate in the gibbon family, Hylobatidae.

The pileated gibbon has sexual dimorphism in fur coloration: males have a purely black fur, while the females have a white-grey colored fur with only the belly and head black. The white and often shaggy hair ring around the head is common to both sexes.

The range of the pileated gibbon is eastern Thailand, western Cambodia and southwest Laos. Its lifestyle is much like other gibbons: diurnal and arboreal, it lives together in a monogamous pair, brachiates through the trees with its long arms, and predominantly eats fruits, leaves and small animals. Reproduction habits are not well known, but are presumed to be similar to the other gibbons.
