Bornean mystery monkey

The Bornean mystery monkey is an unidentified primate in East Malaysia. It is suspected that it may be an intergeneric hybrid between the proboscis monkey (Nasalis larvatus) and silvery lutung (Trachypithecus cristatus), although genetic testing has not yet been conducted to prove this. It was first observed in 2016. In September 2020, the female was seen with a baby.[1][2]
