Loris is the common name for the strepsirrhine primates of the subfamily Lorinae[1] (sometimes spelled Lorisinae[2]) in the family Lorisidae. Loris is one genus in this subfamily and includes the slender lorises, while Nycticebus is the genus containing the slow lorises.
Description
Lorises are nocturnal and arboreal.[3] They are found in tropical and woodland forests of India, Sri Lanka, and parts of southeast Asia. Loris locomotion is a slow and cautious climbing form of quadrupedalism. Some lorises are almost entirely insectivorous, while others also include fruits, gums, leaves, and slugs in their diet.[4]
Female lorises practice infant parking, leaving their infants behind in nests. Before they do this, they bathe their young with allergenic saliva that is acquired by licking patches on the insides of their elbows, which produce a mild toxin that discourages most predators,[4] though orangutans occasionally eat lorises.[5]
Taxonomic classification
The family Lorisidae is found within the infraorder Lemuriformes and superfamily Lorisoidea, along with the family Galagidae, the galagos. This superfamily is a sister taxon of Lemuroidea, the lemurs. Within Lorinae, there are ten species (and several more subspecies) of lorises across two genera:[1]
- Family Lorisidae
- Subfamily Perodicticinae
- Subfamily Lorinae
- Genus Loris
- Gray slender loris, Loris lydekkerianus
- Highland slender loris, L. lydekkerianus grandis
- Mysore slender loris, L. lydekkerianus lydekkerianus
- Malabar slender loris, L. lydekkerianus malabaricus
- Northern slender loris, L. lydekkerianus nordicus
- Red slender loris, L. tardigradus
- Dry Zone slender loris, L. tardigradus tardigradus
- Horton Plains slender loris, L. tardigradus nyctoceboides
- Gray slender loris, Loris lydekkerianus
- Genus Nycticebus
- Bangka slow loris, Nycticebus bancanus
- Bengal slow loris, N. bengalensis
- Bornean slow loris, N. borneanus
- Sunda slow loris, N. coucang
- Javan slow loris, N. javanicus
- Kayan River slow loris, N. kayan
- Philippine slow loris, N. menagensis
- †? N. linglom (fossil, Miocene)
