Description

Habitat

Biome: Terrestrial [1].

Ecology: This species is typically found in forested habitats associated with karst/limestone environments (Pham Nhat 2002). The natural habitat in Quang Binh and Quang Tri is now restricted to a band of forest near the Lao border (Nadler et al. 2003), and forests are heavily degraded in Tuyen Hoa and northern Minh Hoa Districts (Pham Nhat et al. 1996a). In Lao PDR, the species is associated with non-limestone rock outcrops on steep or precipitous mountain slopes . It reaches approximately 1,500 m in elevation . It is folivorous, terrestrial and arboreal , and diurnal .[1].

List of Habitats:

•     1     Forest   
  
•     1.6     Forest - Subtropical/Tropical Moist Lowland   
  
•     1.9     Forest - Subtropical/Tropical Moist Montane

Taxonomy

Synonyms

Trachypithecus ebenus • Trachypithecus francoisi ssp. hatinhesis

Notes

This species is here considered monotypic (Groves 2001). However it may well represent a subspecies of Trachypithecus laotum. The form ebenus is sometimes considered as a distinct species, but more likely represents a morph of this species as there is no genetic difference between ebenus and hatinhensis (Roos 2004). More material is necessary for clarification.[1].
