Gursky's spectral tarsier

Gursky's spectral tarsier, known locally as wusing, is a tarsier found on the island of Sulawesi in Indonesia. A recent taxonomic revision split it from the spectral tarsier and from other tarsier species on the basis of differences in vocalisation and pelage. Like other primates these tarsiers communicate flexibly, giving different note patterns in response to the calls of their duet partner. The species is named for Dr. Sharon Gursky, who studied its behavioural ecology; those studies were first published under the older taxonomy, which classified the population she worked with as the spectral tarsier, Tarsius spectrum, and the new name removes the mismatch between the earlier publications and her study population.
