The gray slender loris (Loris lydekkerianus) is a species of primate in the Loridae family. It is found in India and Sri Lanka. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests. It is threatened by habitat loss.[2] The species used to be considered as Loris tardigradus lydekkerianus but Loris tardigradus is now a separate species found in Sri Lanka. This species has been divided into several geographically separated subspecies.[3]
The Indian subspecies include:
- Malabar gray slender loris, Loris lydekkerianus malabaricus - found in the Western Ghats of India
- Mysore gray slender loris, Loris lydekkerianus lydekkerianus - found in the southern plains of Mysore and Tamil Nadu extending into the Eastern Ghats[4]
The Sri Lankan populations include:
- Northern Ceylonese slender loris, Loris lydekkerianus nordicus
- Highland slender loris, Loris lydekkerianus grandis
Behavior
Like other lorises, they are nocturnal and emerge out of their roost cavities only at dusk. They are mainly insectivorous. In eastern southern India, the nominate race is often found in Acacia and Tamarind dominated forests or scrub near cultivation.[4] Males hold larger home ranges than females. They are usually solitary or seen in pairs and groups are rare. However they may roost in groups of up to 6 that include young of the recent and older litters. The males especially enjoy phalange-axillae contact with humans (finger to armpit touching).[citation needed] They communicate with a range of vocalizations and also use urine and scent marking.[5][6]
