Pygmy lorises have recently been confirmed to occur within Phnom Prich Wildlife Sanctuary in Cambodia’s Eastern Plains Landscape. They are a species of primate found east of the Mekong River in eastern Cambodia, southernmost China , Lao PDR, and Viet Nam. Due to their nocturnal, highly cryptic nature, not much is known of their ecology. However, lorises are hunted opportunistically by indigenous Bunong for use in traditional medicine. The species also seems to be the most common mammal used in traditional Khmer medicines. Protected areas in eastern Cambodia, like Phnom Prich Wildlife Sanctuary, are thus likely to be important areas for the conservation of pygmy loris.
