<i>Rinodina</i> is a lichenized fungal genus belonging to the Physciaceae, with c. 300 species worldwide. Nearly a century ago, Zahlbruckner described five species of the genus <i>Rinodina</i> from Southwest China. The type collections were the only records for these species. In the present study, new records for four of these species: <i>Rinodina cornutula</i>, <i>R. globulans</i>, <i>R. handelii,</i> and <i>R. setschwana</i>, and a recently described species, <i>R. pluriloculata</i>, are documented based on specimens collected from the holotype localities. Furthermore, one new species was discovered: <i>Rinodina hengduanensis</i>, characterized by areolate to subsquamulose thallus, jigsaw-like areoles, lecanorine apothecium, and <i>Dirinaria</i>-type ascospores. <i>Rinodina setschwana</i> is transferred to the genus <i>Buellia</i> based on its morphology, chemistry, and phylogeny and proposed as <i>Buellia setschwana</i>. We provide detailed morphological descriptions, pictures, and molecular phylogenetic analyses.
