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.
2011年至2018年期间，在马来西亚半岛刁曼岛多次发现懒猴（蜂猴属）。本文讨论的记录是自1915年发现以来，首次在刁曼岛确认的蜂猴目击事件和照片证据，驳斥了认为刁曼蜂猴已灭绝的推测。尽管最初被认为是巽他懒猴（马来蜂猴）的一个亚种，但在所有观察到的个体中明显存在的几个形态特征，包括白色的眼间条纹、红褐色的体色和浅色的背部条纹，与菲律宾懒猴（菲律宾蜂猴）相似。此外，宽阔的口鼻部和耳朵可能是这个种群所特有的，这表明该种群可能是独特的。因此，我建议未来的研究考虑偏远和孤立的蜂猴种群的分类地位，因为它们有可能代表不同的、未被认可的分类群。
