Binumarien, or Afaqinna ufa as it is known to its speakers, is a Kainantu language of Papua New Guinea.
The name used in the literature was used under Australian administration and is still used by Binumarien people when they speak Tok Pisin.
[2] Binumarien is spoken by an ethnic group of the same name in Kainantu District, near the easternmost corner of the Eastern Highlands Province.
According the memory of older people, the Binumarien used to be more numerous, but tribal fighting and malaria greatly had reduced their numbers.
[3] Since then, the Binumarien established more stable relations with the surrounding tribes, and moved to a higher altitude, making them less susceptible to malaria.
