Southern Pygmy Slow Loris

The pygmy slow loris is a slow loris found east of the Mekong River in Vietnam, Laos, eastern Cambodia and China, in a variety of forest habitats including tropical dry, semi-evergreen and evergreen forests. It was originally placed in Nycticebus until moved to Xanthonycticebus in 2022; two species are recognised, the northern pygmy loris from northern Vietnam, Laos and China and the southern pygmy loris from southern Vietnam, Laos and Cambodia (Wikipedia, general species account).

It is nocturnal and arboreal, crawling slowly along branches in search of prey, and unlike other primates it does not leap. An adult grows to about 19–23 cm with a very short tail and weighs about 450 g. It is omnivorous, feeding on termites, ants, other insects and fruit; a Vietnamese study found its diet was largely tree gum (63%) and animal prey (33%), and it gouges trees to feed on exudates. It breeds once a year, with gestation of 184–200 days, and weans young at about 24 weeks.
