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 was previously 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:
The Sri Lankan subspecies include:
In Sri Lankan subspecies, Loris lydekkerianus grandis has short ears, and a heart-shaped face. Basal hairs of the vent of Loris lydekkerianus grandis are black and whereas those of Loris lydekkerianus nordicus are white in colour. Behaviour{{clear left}}ReproductionLorises are found to be promiscuous, multiple males competing for one female for mating. Mating occurs biannually, April–June, and October–December.[5] Although mating occurs twice a year, lorises can only breed once a year. One estrus cycle will fail and another will begin approximately 2 weeks following. Gestation is approximately 170 days. Twins are very common among lorises. The reproductive tract and ovarian cycle reflect the general mammalian plans. As far as lactation, four teats develop and produce milk before the infant is born. After giving birth, females are non-receptive to males and care for their young.[9] Geographic DistributionFound endemically in India and Sri Lanka, lorises are distributed along the Western Ghats in Kerala, Karnataka and Western Tamil Nadu continuing along the Eastern Ghats to southern Andhra Pradesh. Lorises prefer dry zones, with scrub and dry tree species. They are also found near plantations, and cultivated areas near taller forests.[10] Threats and ConservationAlthough considered a Least Concern on the IUCN Red List and classified under Schedule I (Part 1) of the Indian Wildlife Act, 1972, the threat to these primates is increasing. Loris is used to make love potions, treat leprosy and eye ailments. Some villagers keep lorises as pets, but because they are difficult to maintain there is high mortality. Some cities have them captive in zoos, and astrologers use them to pick out tarot cards.[11] Food preference for lorises is insects. Farmlands, which are high in cattle waste, produce large amounts of insects. This is ideal for the species and because these animals are competing with humans over food they aren't not afraid of interaction. There is a high interaction occurrence with humans and lorises around cultivated/farmlands.[12] Habitat fragmentation is also a threat to the loris population, as well as loss of acacia trees, which is a preferred tree species for the loris.[10] Conservation efforts are developing and more research on conservation efforts are ongoing.[4] References1. ^{{MSW3 Groves | pages = 122}} 2. ^1 2 {{Cite journal | author = Nekaris, A. | author2 = Singh, M. | author3 = Kumar Chhangani, A. | last-author-amp = yes | title = Loris lydekkerianus | journal = The IUCN Red List of Threatened Species | volume = 2008 | page = e.T44722A10942453 | publisher = IUCN | date = 2008 | url = http://www.iucnredlist.org/details/44722/0 | doi = 10.2305/IUCN.UK.2008.RLTS.T44722A10942453.en | access-date = 12 January 2018}} 3. ^{{cite journal |author=Perera, M.
