Black-footed gray langur

The black-footed gray langur ("Semnopithecus hypoleucos") is an Old World monkey, one of the species of langurs. This, like other gray langurs, is a leaf-eating monkey found in south India.
Taxonomy.
The black-footed gray langur was previously considered to be a subspecies of "Semnopithecus entellus". Research done in 2003 by Brandon-Jones may indicate that it is a subspecies of "Semnopithecus dussumieri". Some experts believe that the species may be a naturally occurring hybrid of "Semnopithecus johnii" and "Semnopithecus dussumieri". Currently "S. dussumieri" is considered a junior synonym of the black-footed gray langur.
Distribution.
This black-footed gray langur is distributed throughout south-western India (Goa, Karnataka and Kerala), but is centred on the Western Ghats. Its total range is around 35,000 km2, with the species living inside and outside of protected areas.
