New subspecies of Philippine tarsier discovered

Tiny, nocturnal primate lives in area threatened by mining

WELCOME TO THE FAMILY  Genetic tests have cleared up confusion over the taxonomy of the Philippine tarsier and have identified a new subspecies of the rare primate.

Genetic tests have spotted a new subspecies of Philippine tarsier, one of the world’s smallest — and arguably cutest — primates. Previously, taxonomists had used physical features, such as body proportion and hair color and length, to determine that there are anywhere between three and seven subspecies of this rare nocturnal mammal. To clarify that confusion, Rafe Brownof the University of Kansas in Lawrence and other researchers recently examined DNA samples collected from tarsiers from across the southeastern Philippines. The comparison divvied the tarsiers into five lineages, including an unexpected variety on Dinagat Island and the Caraga region of nearby Mindanao Island. Wildlife sanctuaries partially encompass the habitats of the four other lineages, but the realm of the Dinagat-Caraga tarsier has historically lacked protection and is threatened by recent expansion of mining activities, the scientists report August 19 in PLOS ONE.
