International audience. Two East Asian Lomariopsis (Lomariopsidaceae, Polypodiales) species, Lomariopsis moorei and Lomariopsis longini , which were previously misidentified as L. spectabilis , are here described as new species based on evidence from morphological characters and a molecular phylogeny. The two species differ from the three other described species in East Asia by their venation, pinna shapes, and perine morphology. A phylogeny based on a combined dataset of three chloroplast regions ( rbcL + rps4-trnS + trnL-L-F ) showed that L. moorei and L. longini each formed a well-supported monophyletic group which was distantly related to both L. spectabilis and the other morphologically similar East Asian species, L. boninensis .
