Discusión taxonómica
This is relatively common in rain forest areas of Guerrero, Oaxaca, Veracruz, and Chiapas, but uncommon or rare elsewhere in Mexico. It is superficially similar to some species of Radiovittaria, especially R. remota (Feé) E. H. Crane in tropical America, but the latter has distinct, darkened stipes, marginal commissural veins, and lacks hexagonal areoles. In blade shape, Ananthacorus is also similar to Polytaenium lineatum, which differs in having 4–6 linear sori per frond.A
