Slow loris [SEP] Discovery and taxonomy
In 1812, Étienne Geoffroy Saint-Hilaire named the genus "Nycticebus", naming it for its nocturnal behavior. The name derives from the , genitive form of (, "night"), and (, "monkey"). Geoffroy also named "Nycticebus javanicus" in this work. Later 19th-century authors also called the slow lorises "Nycticebus", but most used the species name "tardigradus" (given by Linnaeus in 1758 in the 10th edition of "Systema Naturæ") for slow lorises, until mammalogists Witmer Stone and James A. G. Rehn clarified in 1902 that Linnaeus's name actually referred to a slender loris.
