Abstract: Members of the poorly investigated family Teloschistaceae in South America, mostly from Bolivia and Peru, were examined using molecular and morphological data here for the first time. In recent phylogenetic reclassifications of Teloschistaceae, South American representatives were poorly represented but shown to belong to subfamilies Teloschistoideae and Xanthorioideae. In this study, we expanded the sampling of South American taxa and investigated mainly the lobate, sublobate, and squamulose members of Caloplaca s.l., using morphological characters and a molecular phylogeny based on a combined three-locus data set (one mitochondrial and two nuclear loci). Building upon new phylogenies at the family and subfamily levels (Teloschistoideae), we propose here three new genera: Andina, Aridoplaca, and Cinnabaria, with the type species Andina citrinoides, Aridoplaca peltata, and Cinnabaria boliviana. We also propose to reduce Tarasginia to synonymy with Sirenophila and Tayloriellina to synonymy with Villophora and introduce three new combinations: Dufourea ottolangei, D. volkmarwirthii, and Villophora erythrosticta. Scutaria andina is reported as new to Bolivia. A critical revision of the subfamily Brownlielloideae confirmed recent findings that it is an artifactual taxon based on a “chimeric” data set, with the type genus being part of Teloschistoideae.
