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.

南美 Teloschistaceae（地衣子囊菌，Teloschistales）的系统发育修正揭示了三个新属和种

在南美洲，主要来自玻利维亚和秘鲁的未充分研究的 Teloschistaceae 成员在这里首次使用分子和形态学数据进行了检查。在最近对 Teloschistoideae 的系统发育重新分类中，南美代表的代表性较差，但显示属于 Teloschistoideae 和 Xanthorioideae 亚科。在这项研究中，我们扩展了南美类群的采样，主要研究了 Caloplaca sl 的叶状、亚叶状和鳞状成员，使用形态特征和基于组合三基因座数据集（一个线粒体和两个核基因座）的分子系统发育）。基于科和亚科水平的新系统发育（Teloschistoideae），我们在此提出了三个新属：Andina、Aridoplaca 和 Cinnabaria，以及模式种 Andina citrinoides，Aridoplaca peltata 和 Cinnabaria boliviana。我们还建议将 Tarasginia 减少为 Sirenophila 的同义词，将 Tayloriellina 减少为 Villophora 的同义词，并引入三种新组合：Dufourea ottolangei、D. volkmarwirthii 和 Villophora erythrosticta。据报道，Scutaria andina 是玻利维亚的新品种。Brownlielloideae 亚科的重要修订证实了最近的发现，即它是基于“嵌合”数据集的人工分类群，类型属是 Teloschistoideae 的一部分。
