SOUTH–WESTERN LANGUR/Behaviour, Distribution, Habitat, Size, Weight, IUCN stetus


DESCRIPTION: An average-sized crestless langur and with a backward- looped tail. It has a brownish streak between the eye and ear. The three or four subspecies can be told apart by the varying amount of black on the hands and arms as well as the general coat colouration. In the northern subspecies S.h. achates, the coat colouration is brownish orange tending to more bright orange or buff on the chest. This colouration is similar for S.h. iulus as well, which it overlaps with in general distribution. Both subspecies have dark paws only up to the wrist. S.h. iulus in the field can only be distinguished by its darker orange pelage and by the habitat that it occupies. S.h. hypoluecos can be easily told apart from both the above subspecies as the dark hands and legs extend up to the elbow and thigh. Both the back and the ventral parts are greyish and there is no trace of orange in the pelage. There is still some debate about the validity of S.h. aeneas as a subspecies, but in the field, this type of form can be told apart from the fact that the darkness extends up to the shoulders as well. The pelage colour has some traces of orange as well, which is missing in S.h. hypoleucos.

BEHAVIOUR: None recorded.

DISTRIBUTION: S.h. achates, from south of River Narmada or Baruch in Gujarat to Nagarhole in Karnataka in the south. S.h. iulus, from Bhimashankar in Maharashtra through the Konkan up to Coorg, and S.h. hypoleucos, south of Shimoga to the Brahmagiris and Wayanad in Kerala. The Brahmagiris and Nilgiris is where these forms intergrade.

HABITAT: All habitats, including plantations; also found near human settlements. S.h. achates, in drier areas, S.h. hypoleucos in moist deciduous to evergreen forests, and S.h. iulus in more moist forests.

Size: 55–75 cm
