Asia-Tropical, Eastern New Guinea present
Malesia: Widely in Eastern New Guinea, in forest at 400-1300 m.
Christ described only a fertile frond and noticed neither glands nor reduced pinnae. Copeland confused this species with Amphineuron attenuatum (O. Ktze) Holttum in the Philippines (Fern Fl. Philip. 341) and with Dryopteris logavensis Rosenst. (Amphineuron pseudostenobasis (Copel.) Holttum) in New Guinea. Holttum and Roy misidentified a cul- tivated plant as Cyclosorus heterocarpus and reported a chromosome count 2n = 72.
