The Mysore slender loris, Loris lydekkerianus lydekkerianus is a nocturnal strepsirrhine primate endemic to India. As with other lorisine species, there have been few studies on this taxon and much still remains unknown about it. During a 21-month study on a Mysore slender loris population in Tamil Nadu, southern India, we collected data on the ecology and behaviour of 32 identified individuals. Certain aspects of diet and social behaviour of lorises in this population vary from what is already known for the Mysore slender loris in another part of southern India, offering a new perspective into behavioural variations in this taxon. Evidence for behavioural variation in the Mysore slender loris is significant for two reasons ? one, there are few instances of clearly documented intraspecific variation in wild nocturnal primate species and two, this flexibility, it would appear, allows the Mysore slender loris to inhabit and survive in degraded and disturbed habitats across southern India, an adaptability that is thus critically linked to its conservation status.
