The Hatinh langur^[1] (Trachypithecus hatinhensis) is a critically endangered Old World monkey found in the limestone forests of Vietnam, particularly in Quảng Bình province.

• These graceful langurs are long, slender, and muscular, with glossy black fur covering their entire body and tail.
• The band of white fur that sticks out from their cheeks looks like a delicate brushstroke, giving them a distinguished look.
• It extends above and behind the rounded ears to the nape of the neck. Their oval, smooth face is crowned by a spiky strand of hair.
• Their eyes are brown, and their nostrils are slanted downwards.
• They have 5 digits on their feet and hands, which makes them very dexterous.

• Contrary to their common name, the Hatinh langur is not known from the province of Hà Tĩnh.
• The local Van Kieu minority calls this lutung “Con Cung“, which roughly translates to “long-tailed black rock monkey“.
• This largely arboreal and diurnal langur is gregarious and is usually seen in groups of 2 to 15. Still, occasionally groups can include up to 30 individuals.
• Hatinh langurs prefer walking to suspensory locomotion, though they choose the latter mode of locomotion when they need to travel long distances, which is facilitated by swinging from one branch to another.
• Langurs make their roosts in small burrows and limestone caves sheltered from predators, rain, and cold.
