Pygmy tarsiers, long believed extinct, have been found in Indonesia, according to a story in The Globe and Mail. In August, researchers from Texas A&M, led by Sharon Gursky-Doyen, trapped two males and a female in moutain-top mist nets on Mt. Rore Katimbo in Lore Lindu National Park in Central Sulawesi, Indonesia. With distinctive eyes, the pygmy tarsiers are primates; they are"about the size of a small mouse;" they have claws instead of nails, which is a distinguishing feature.
Here's a short video from the researchers showing the pygmy tarsier running up a tree.
