In the course of a yeast biodiversity survey of different ecological habitats found in Ecuador, two yeast strains (CLQCA 20-011(T) and CLQCA20-014) were isolated from samples of rotten wood and fallen leaf debris collected at separate sites in the central region of the Ecuadorian Amazonia. These strains were found to represent a novel yeast species based on the sequences of their D1/D2 domain of the large-subunit (LSU) rRNA gene and their physiological characteristics. Phylogenetic analysis based on LSU D1/D2 sequences revealed this novel species to be most closely related to Candida asparagi, Candida fructus, Candida musae and two as yet undescribed Candida species, with the six yeast taxa collectively forming a distinct species group within the Clavispora clade. The species name of Candida carvajalis sp. nov. is proposed to accommodate these strains, with CLQCA 20-011(T) (NCYC 3509(T), CBS 11361(T)) designated as the type strain.
在对厄瓜多尔不同生态栖息地进行的酵母生物多样性调查过程中，从厄瓜多尔亚马逊地区中部不同地点采集的朽木和落叶碎片样本中分离出两株酵母菌株（CLQCA 20 - 011(T)和CLQCA20 - 014）。基于大亚基（LSU）rRNA基因D1/D2结构域序列及其生理特征，发现这些菌株代表一个新的酵母物种。基于LSU D1/D2序列的系统发育分析表明，这个新物种与芦笋假丝酵母、果实假丝酵母、香蕉假丝酵母以及另外两个尚未描述的假丝酵母物种关系最为密切，这六个酵母分类单元共同在克勒克酵母分支内形成一个独特的物种组。提议将这些菌株归为卡瓦哈尔假丝酵母新种（Candida carvajalis sp. nov.），并指定CLQCA 20 - 011(T)（NCYC 3509(T)，CBS 11361(T)）为模式菌株。
