The Wallace tarsier ( Tarsius wallacei ) is a species of primate from the group of tarsier . The species was only described in 2010 and named in honor of Alfred Russel Wallace .
distribution
The Wallace tarsier occurs in central Sulawesi in two isolated populations. The northern population lives in the west or south of the Semenanjung Minahassa Peninsula, the southern population has a much smaller distribution area and is separated from the northern population by the Palu Bay and the city of Palu , exclusively in a very small area directly south of Palu in front.
features
The Wallace tarsier grows to about twelve centimeters long and is similar to other tarsier of the Sulawesi lowlands. The head is exactly the same size as that of the Diana tarsier ( T. dentatus ) and the Lariang tarsier ( T. lariang ), but the ears are larger, fingers and toes shorter. The fur of the new species is speckled, yellowish-brown, the belly cream-colored, the neck copper-colored. The mottled appearance is caused by the gray undercoat and the scattered light gray to black tips of the hair. The eyes are surrounded above and below by yellow to copper-colored spots, which in most specimens form an almost complete eye ring. The light belly is not the same in all individuals, but varies in size and color between white and cream. As with other tarsier species from central Sulawesi, the tail is dark, with a thick black tassel at the end. The Wallace tarsier can be distinguished from other species mainly by its characteristic duet song.
Its two populations differ markedly in their body size, but have the same color, a similar, bushy tail tassel, comparable vocalizations and a similar genome.
