Jatna's tarsier

Jatna's tarsier, known locally as mimito, is a tarsier endemic to northern Sulawesi, in Gorontalo, Indonesia. It was formerly grouped with the spectral tarsier and was raised to species rank in 2017 after a team led by Myron Shekelle in the Nantu Wildlife Reserve found that its male and female duet calls differ from those of other populations. It is named for the Indonesian conservationist Jatna Supriatna. It lives in tropical rainforest, nesting in dense clumps of palm and bamboo, and is fully carnivorous, feeding mostly on insects such as moths and crickets and on small lizards and frogs. Males weigh about 135 grams and females 104 to 114 grams. It was rated Vulnerable on the IUCN Red List in 2020 with a decreasing population, and has lost an estimated 12 percent of its forest habitat between 2000 and 2017.
