Pongo tapanuliensis, a New Orangutan Species/ Curr. Biol., Nov. 2, 2017 (Vol. 27, Issue 22)

Nater et al. describe a new great ape species, the Tapanuli orangutan Pongo tapanuliensis. An isolated population from Batang Toru, the southernmost orangutan population in Sumatra, has evolved independently from the northern Sumatran and Bornean species. Their evidence is based on population genomic analyses, as well as morphological and behavioral variation. Fewer than 800 individuals of P. tapanuliensis survive in the wild.
