Several slow loris (Nycticebus) sightings have occurred on the island of Pulau Tioman, Peninsular Malaysia, from 2011 to 2018. Records discussed here represent the first confirmed sightings and photographic evidence of Nycticebus on Tioman since its discovery in 1915, refuting presumptions that the Tioman slow loris is extinct. Although originally considered a subspecies of the Sunda slow loris (Nycticebus coucang), several morphological characteristics apparent in all observed individuals, including the white interocular stripe, rufous colouration and pale dorsal stripe, are similar to the Philippine slow loris (Nycticebus menagensis). Further, the broad snout and ears may be unique to this population and suggest that the population may be distinct. I, therefore, recommend that future studies consider the taxonomic status of remote and isolated Nycticebus populations given the possibility that they may represent distinct and unrecognised taxa.
