Lariang tarsier

The Lariang tarsier (Tarsius lariang) is a recently described tarsier occurring in the western part of the central core of Sulawesi. Six museum specimens of this species are known, two of which have been misidentified as the pygmy tarsier before their correct identity came out. This species has been named after the Lariang River, an important river in the part of Sulawesi where this species occurs.

This species has darker fur than the other Sulawesi tarsiers. The dorsal fur is greyish brown. The blackish tail ends in a dark pencil-like point. There is a clearly discernible dark ring around the eyes. The third digit on the hands is very long. It's the second largest tarsier; only the Sangihe tarsier is larger; published body weights are 67 to 117 g.
