摘要：

A new species of liana, Dicranostyles yrypoana (Convolvulaceae) is described from the Central Amazon rainforest in Brazil. The specimens of D. yrypoana remained with dubious identification in herbaria for at least 60 yr. This new species is distinguished from other species of Dicranostyles mainly for its tomentose leaves, in addition to its cylindric glabrous ovary, short style (0.5-0.6 mm long), and globose stigma. The specific epithet yrypoana refers to yripo, which means liana in the language of the Satere-Mawe people that originally live in the region of occurrence of this new species. We provide morphological and palynologic descriptions, a distribution map, illustrations, taxonomy comments, an identification key, and comparisons with similar species. Dicranostyles yrypoana is informally assessed as Endangered (EN) based on IUCN criteria and guidelines.
