The Arfak Cryptocarya is a small tree that is known only from the type material that was collected in 1940 in the Arfak Mountains in the West Papua Province of the Indonesian part of New Guinea.
The species has never been recorded since; given the constant threat of deforestation and habitat destruction, it is possible that it is already extinct.
