Notes on Species of <i>Amauropelta</i> (Thelypteridaceae) with Scandent Leaves in Colombia

Abstract— Amauropelta stands as the most diverse genus of Thelypteridaceae with 233 species in four recognized subgenera. Among these, Amauropelta subgen. Amauropelta includes A . sect. Lepidoneuron , which has scandent leaves. Historically, species delineation has been challenging in this section. Recent explorations in Colombian páramos have uncovered the need for two new combinations in A. sect. Lepidoneuron from the region: Amauropelta sunduei and Amauropelta atropurpurea . Additionally, our investigations have revealed a new synonym and a new distribution record for Amauropelta laevigata. A lectotype is also assigned for one of the synonyms of Amauropelta laevigata . We present descriptions, line drawings of Amauropelta sunduei , preliminary conservation status for species restricted to Colombia, macro- and microphotographs, distribution maps, and a key for all species discussed.
