Six strains of a novel yeast species were isolated from tree bark collected in the Atlantic Forest and the Amazon Rainforest in Brazil. Analyses of the sequences of D1/D2 domains of the large subunit rRNA gene showed that the strains belong to a species in the genus . The species differed by 5.54 % sequence divergence (25 substitutions and five indels out of 542 bp) in the D1/D2 sequences from , its closest relative. The ITS sequence of the type strain of the novel species differs by 27-69 nucleotide substitutions/indels from the other species. The novel species is able to grow on trehalose, maltose, l-sorbose, inulin and at 37 °C, which are negative in . The name sp. nov. is proposed. The holotype of sp. nov. is CBS 16118. The MycoBank number is MB 833702.
从巴西大西洋森林和亚马逊雨林采集的树皮中分离到 6 株新型酵母菌株。对大亚基 rRNA 基因 D1/D2 结构域序列的分析表明，这些菌株属于. 种。与亲缘关系最近的种（.）相比，D1/D2 序列的差异为 5.54%（542bp 中有 25 个替换和 5 个插入缺失）。新型种的 ITS 序列与其他种相比，有 27-69 个核苷酸替换/插入缺失。该新型种能在海藻糖、麦芽糖、l-山梨醇、菊粉和 37°C 下生长，而在 中则为阴性。提议使用. 新种。新型种的模式菌株为 CBS 16118。其对应的 MycoBank 编号为 MB 833702。
