Endangered
Hatinh langur
Trachypithecus hatinhensis
The Hatinh langur is a highly threatened Old World monkey found in limestone forests in Vietnam, primarily in the Quảng Bình Province.
The Old World monkey
Hatinh langur is an Old World monkey in the family Cercopithecidae (order Primates) — Trachypithecus hatinhensis.
Range and habitat
Hatinh langurs inhabit the steep limestone cliffs of Central Vietnam and Southern Laos, prompting them to be referred to as the "Limestone Langur". Their intense preference for these limestone cliffs may be an effect of widespread habitat loss. The Hatinh langur is a highly threatened Old World monkey found in limestone forests in Vietnam, primarily in the Quảng Bình Province.

Diet
Their diet was reported to consist of 81% leaves, 9% fruits, 9% vines, and 1% flowers based on a single study. The Hatinh langur is diurnal, leaving their caves at dawn and return early in the afternoon.
In crisis
They're also subject to hunting from humans that further contributes to their endangered status. The Hatinh langur is labeled as an endangered and decreasing species, with populations that are considered severely fragmented and in decline with regard to mature individuals. As the Hatinh langur relies on limestone forests, deforestation poses another threat.
New construction and forest clearance have resulted in habitat fragmentation, that makes dispersal increasingly difficult, and raises concerns of decline in population sizes resulting in loss of genetic diversity due to genetic drift and inbreeding.
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
