Abstract: Morphological, chemical and phylogenetic examination of specimens observed in situ and of herbarium specimens of the lichen genera Hypotrachyna and Remototrachyna (Parmeliaceae, Ascomycetes) revealed the presence of 12 species in northeastern Argentina. Three of them, H. osseoalba, H. subformosana, and R. costaricensis, are recorded for the first time for the country. The known distribution range of other eight species in the region is also extended. Distribution and comments are presented for all species, and descriptions and illustrations for most relevant records. The phylogenetic relationships of the species of Hypotrachyna and Remototrachyna reported from northeastern Argentina are analyzed, using 15 newly generated ITS sequences together with sequences downloaded from GenBank.
