Tarsius spectrumgurskyae is a primate species from the goblin tarsier group . It was described in 2017and named in honor of Sharon Gursky, an Indonesian primate expert who researched the species for years. At that time it was still carried under the scientific name Tarsius spectrum ,which is no longer in use today. In her homeland she is called Tangkasi or Wusing ; English as a common name was Gursky's spectral tarsier proposed.
The species occurs only in the east of the northern peninsula of Sulawesi (Semenanjung Minahassa) between Tangkoko and the isthmus near Kota Gorontalo . The peninsula is home to numerous endemic species, ie species that only occur here, including two other primates, the crested macaque ( Macaca nigra ) and the Gorontalo macaque ( M. nigrescens ).
features
Tarsius spectrumgurskyae hardly differs morphologically from other Sulawesi tarsier. It is smaller than the Diana tarsier ( Tarsius dentatus ). Females reach a weight of 95 to 119 g, males are slightly heavier at 104 to 126 g on average. The tail is comparatively short (213 to 268 mm for females and 220 to 258 mm for males) and reaches a length of 121 to 210% of the length of the head. The tuft of hair at the tail end is long, thick and black. The fur of the animals is, like most of the Koboldmakis found on the main island of Sulawesi, gray to yellow-brown, the limbs are significantly more brown in color than the rest of the body. The dark circles are black, the black spot next to the nose is clearly defined. Noticeable is a white spot on the sides of the upper lip. There is a small hairless area at the base of the ears. The tip of the nose is clearly convex. The rows of teeth are quite long but variable. The upper molars are narrow. There is a pronounced diastema between the incisors and the canine . Tarsius spectrumgurskyae can be distinguished from other Sulawesi tarsier mainly on the basis of the different vocalizations.
Systematics
The British-Australian primatologist Colin Groves and his colleague Myron Shekelle established in 2010 that the tarsier of the northern peninsula of Sulawesi (Semenanjung Minahassa) is an independent species . However, they did not publish a formal description of a new tarsier species, but instead referred to them in their revision of the tarsier system as Tarsius sp 1. In May 2017, the first description was finally made up. The goblin lemurs of the eastern and central parts of Semenanjung Minahassa were described as two different species ( T. spectrumgurskyae and T. supriatnai ), which are said to have separated from each other about 300,000 years ago.
