Collections from different geographic regions were lumped into E. tozeri based on morphology, but a molecular confirmation was lacking so far. Here, we tested species concepts in the genus Epipterygium, with a special focus on the E. tozeri species complex, combining morphological and DNA sequence data for the nuclear ribosomal ITS region and two plastid loci (trnG intron, trnT-psbD spacer). In a second step, we reconstructed the historical biogeography of the genus. We found that Epipterygiummost likely originated inAsia orNorth/CentralAmerica and that the alleged singlewidespread species E. tozeri with disjunct ranges is in fact a group of genetically andmorphologically distinct taxa, including four overlooked species, forwhichwe provide descriptions: E. atlanticumsp. nov., E. biauritumsp. nov., E. oreophilumsp. nov., and E. yunnanense sp. nov. The biogeographical history of these species is best explained by a step-wise parallel colonization of the Eurasian and American continents followed by in-situ speciation.
