Abstract Based on an analysis of five plastid markers ( atpA , atpB rbcL rps4‐trnS trnL/trnL‐trnF ), we show that Diplazium lechleri is sister to a clade formed by the Hemidictyaceae and Aspleniaceae. Thus, it does not belong Athyriaceae where previously classified. A new family, Desmophlebiaceae, genus, Desmophlebium are described accommodate this relationship. Morphologically, distinguished from combination thick 1‐pinnate laminae, entire pinnae, decurrent distal conform lamina apices (i.e., terminal segment similar lateral pinnae), presence submarginal connecting vein. On basis morphology, also assign longisorum family genus. Accordingly, combinations D. provided. lectotype designated for parallelogrammum synonym lechleri. grows in humid forests 125 1900 m. occurs Panama north‐central northeastern Brazil, Colombia, Ecuador, Peru.
