A monkey with ghostly white circles around its eyes is among 224 new species listed in the World Wildlife Fund’s latest update on the greater Mekong region.

The conservation group’s report, released Wednesday, highlights the need to protect the rich biodiversity and habitats in the region, which includes Vietnam, Cambodia, Laos, Thailand and Myanmar.

The species listed were found in 2020 but last year’s report was delayed. The monkey, a new species of Popa langur found on the extinct Mt. Popa volcano in Myanmar, was the only new mammal. There are also dozens of newly identified reptiles, frogs and newts, fish and 155 plant species, including the only known succulent bamboo species, found in Laos.

The Mekong region is a biodiversity hotspot and home to tigers, Asian elephants, saola — an extremely rare animal also called the Asian unicorn or spindlehorn — and thousands of other species.
