About the Hatinh Langur

The Hatinh langur (Trachypithecus hatinhensis) is a highly threatened Old World monkey found in limestone forests in Vietnam, primarily in the Quảng Bình Province. They are a primarily black, arboreal, and diurnal monkey. They occupy dense forests which contribute to their decline as a result of habitat fragmentation. They're also subject to hunting from humans which further contributes to their endangered status.

Adults of the Hatinh langur are almost entirely black at adulthood, besides a slight dark brown hint, while newborns have yellow fur. Adults feature white coloration on the cheeks that extends past the ears and tapers down the neck. This white coloration fluctuates from a bright white to a smoky grey. Female Hatinh langurs possess light colored hairs in the pubic area, which remains the typical way to determine sex in the field.

The Hatinh langur has often been considered a subspecies of the François' langur, but they were elevated to a full species status by Bradon-Jones in 1995. Species status was later confirmed by Groves, 2005. They have also been listed as a subspecies and genetic work suggests they should be considered a subspecies... Wikipedia →
