The genus Rinodina (Physciaceae), with approximately 300 species, has been subject to few phylogenetic studies. Consequently taxonomic hypotheses in Rinodina are largely reliant on phenotypic data, while hypotheses incorporating DNA dependent methods remain to be tested. Here we investigate Rinodina degeliana/R. subparieta and the Rinodina mniaraea group, which previously have not been subjected to comprehensive molecular and phenotypic studies. We conducted detailed morphological, anatomical, chemical, molecular phylogenetic and species delimitation studies including 24 newly sequenced specimens. We propose that Rinodina degeliana and R. subparieta are conspecific and that chemical morphs within the R. mniaraea group should be recognized as distinct species. We also propose the placement of the recently described genus Oxnerella in Physciaceae.

形态学、化学和物种界定分析为两组犀牛提供了新的分类学见解。

Rinodina 属（Physciaceae）大约有 300 种，很少进行系统发育研究。因此，Rinodina 的分类学假设在很大程度上依赖于表型数据，而包含 DNA 依赖方法的假设仍有待检验。在这里，我们调查 Rinodina degeliana/R。subparieta 和 Rinodina mniaraea 组，以前没有进行过全面的分子和表型研究。我们进行了详细的形态学、解剖学、化学、分子系统发育和物种界定研究，包括 24 个新测序的标本。我们建议 Rinodina degeliana 和 R. subparieta 是同种的，并且 R. mniaraea 组内的化学形态应被视为不同的物种。我们还建议将最近描述的 Oxnerella 属放置在 Physciaceae 中。
