Four strains of yeasts isolated in Thailand and Taiwan were found to represent four distinct novel species of the ascomycetous anamorphic yeast genus Candida. These strains are located in the Clavispora-Metschnikowia clade in a phylogenetic tree based on the D1/D2 domain sequences of the large subunit rRNA genes. Together with Candida picinguabensis and Candida saopaulonensis, the four novel species constitute a well-separated subclade from other species of the Clavispora-Metschnikowia clade. Three species from Thailand are described as Candida bambusicola sp. nov. (type strain, ST-50(T) = BCC 7750(T) = NBRC 106734(T) = CBS 11723(T)), Candida nongkhaiensis sp. nov. (type strain, ST-95(T) = BCC 8331(T) = NBRC 105874(T) =CBS 11724(T)) and Candida succicola sp. nov. (type strain, ST-631(T) = BCC 15314(T) = NBRC 106736(T) = CBS 11726(T)), respectively, and the species from Taiwan is described as Candida touchengensis sp. nov. (type strain, SY4S03(T) = NBRC 102647(T) = BCRC 23097(T) = CBS 10585(T)).
在泰国和台湾分离出的四株酵母被发现代表子囊菌无性型酵母属念珠菌的四个不同新物种。基于大亚基rRNA基因的D1/D2结构域序列构建的系统发育树显示，这些菌株位于克勒克酵母属-梅奇酵母属进化枝中。这四个新物种与皮钦瓜念珠菌和圣保罗念珠菌一起，构成了一个与克勒克酵母属-梅奇酵母属进化枝中其他物种明显分离的亚进化枝。来自泰国的三个物种分别被描述为竹生念珠菌（新种，模式菌株ST-50(T)=BCC 7750(T)=NBRC 106734(T)=CBS 11723(T)）、廊开念珠菌（新种，模式菌株ST-95(T)=BCC 8331(T)=NBRC 105874(T)=CBS 11724(T)）和多汁念珠菌（新种，模式菌株ST-631(T)=BCC 15314(T)=NBRC 106736(T)=CBS 11726(T)），来自台湾的物种被描述为头城念珠菌（新种，模式菌株SY4S03(T)=NBRC 102647(T)=BCRC 23097(T)=CBS 10585(T)）。
