Range Description

This species is widely distributed in southern India and Sri Lanka.

S. p. priam
Occurs south of river Krishna in Andhra Pradesh to Madurai in Tamil Nadu, but the actual areas of occupancy are sparse in between (Molur et al. 2003), with large areas absent of langurs. The forests of the Eastern Ghats are not contiguous, have highly degraded dry deciduous forests, and are for the most part scrubby. The ratio of extent of occurrence to area of occupancy is very high (A. Kumar, M. Singh and S. Molur pers. comm.).

S. p. thersites
It is found in the southern Western Ghats in India and in the dry zone of Sri Lanka. However, there are some
populations of langurs on the foothills of southern India along the western slopes of the Western Ghats and in the Palghat gap, whose identity has not been established. Extent of occurrence is around 10,000 km^{2 in India and around 40,000 km2 in Sri Lanka. Area of occupancy is almost contiguous in the Indian portion, while it is about one-fourth in Sri Lanka.}
