Jatnas Koboldmaki ( Tarsius supriatnai ) is a species of primate from the group of Koboldmakis . It was described in 2017 and named in honor of Jatna Supriatna, an Indonesian biologist who works to preserve Indonesia's biodiversity. The species occurs only in the middle of the northern peninsula of Sulawesi (Semenanjung Minahassa) between Ogatemuk and the isthmus near Kota Gorontalo . In her homeland she is called Mimito; Jatna's tarsier was suggested as an English common name.
features
Jatna's tarsier does not differ morphologically from other Sulawesi tarsier ; T. spectrumgurskyae is particularly similar, but occurs further east on the same peninsula and was described at the same time. In contrast to this species, Jatna's tarsier has, in most cases, a larger hairless area at the base of the ears, a longer hind foot, a longer tail and a longer middle finger. In addition, the first and second molars are larger (the third is not) and the front central incisor is not as high. The previously weighed females of Jatna's tarsier weigh between 104 and 114 g, the only male examined weighed 135 g. It is possible that the dimorphism in terms of weight is a little more pronounced in this species than in other tarsier. The tail of the examined females is 232 to 243 mm long, that of the male is 246 mm long. Jatna's Koboldmaki can be distinguished from other Sulawesi Koboldmaki 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.
