Siau Island tarsier [SEP] parent taxon
Siau Island tarsier
The Siau Island tarsier ("Tarsius tumpara") is a species of tarsier from the tiny volcanic island of Siau.
Its existence as a distinct taxon was predicted by the hybrid biogeographic hypothesis for Sulawesi. The rationale was that a geographic discontinuity existed between the northern tip of Sulawesi, and the population of tarsiers on Sangihe Island (the Sangihe tarsier "Tarsius sangirensis"), approximately to the north. In between, lay very deep oceans and three island clusters, Biaro, Tagulandang/Ruang,
