Description
Summary:A new species, Campyloneurum atrosquamatum , is described from the western Amazonian region of Ecuador to Bolivia, and from French Guiana and northeastern Brazilian Amazon. The new species belongs to the Repens Clade of Campyloneurum . Previously, it had been identified as C. coarctatum because of its similar lamina size and shape. An earlier phylogenetic study, however, resolved it as sister to C. fuscosquamatum, a species with nearly identical rhizome scales and a similar geographic distribution. We describe the new species, compare it to related species, and provide illustrations, distribution maps, and a key to similar species. A lectotype is chosen for C. coarctatum.
