Semnopithecus hypoleucos Blyth, 1841 – South-western Langur

Taxonomic Notes:

South-western Langur or Black-footed Grey Langur was once considered as one of the several subspecies under Semnopithecus entellus species complex now split as separate species recently. There are debates suggesting this to be either a subspecies of Southern Plains grey Langur (S. dussumieri) or this species being a hybrid of Nilgiri Langur (S. johnii) and southern plains Grey Langur. However, it is now established that this is an entirely different species. 

 This species is listed as Vulnerable in the IUCN Red List of Threatened Species (

Status, Habitat and Habits:

This species is also known as Black-footed Grey Langur. There are few more alternative names available e.g. Dark-legged Langur, Dark-legged Malabar Langur or Malabar Sacred Langur. It is endemic to India and distributed in Western Ghats of Goa, Karnataka and Kerala. It is mainly an arboreal species that forages on leaves and fruits but can be found frequenting forest floors. 

Conservation Status:

 This species is listed as Vulnerable in the IUCN Red List of Threatened Species (

According to IUCN Red List assessment, population of this species is decreasing all over its range. It is predicted that its population may decrease by 30% within ~30 years. There is no data on its population estimates in recent years. Major threats to this species are habitat loss and fragmentation due to residential and commercial development, expanding agruiculture, logging and mining. Another challenge it faces in certain areas is hunting, which is believed to be a more serious issue.
