We propose Cryptonemia asiatica sp. nov. from Korea and Japan. We used molecular analyses of plastid-encoded rbcLand morphological observations to resolve the taxonomic identities of C. lactuca from Korea, C. luxurians from Japan,and C. seminervis from Spain. Specimens of C. lactuca and C. luxurians fell within the same molecular phylogenetic clade(with 100% bootstrap support) and were clearly separated from specimens of C. luxurians collected from the type localityin Brazil. Our analyses demonstrated identical molecular sequences between C. seminervis specimens from Spain andC. lomation specimens from France. Morphological characteristics of the new species, C. asiatica include prominentmidribs through the mid thallus, a cortex 4–6 cells thick, and a blade with undulate margins. Molecular evidence indicatesthat specimens from Korea and Japan previously assigned to C. lactuca and C. luxurians, respectively, should bereassigned to Cryptonemia asiatica. Binomial C. luxurians from Brazil should be resurrected as the independent speciesof Cryptonemia. KCI Citation Count: 2
