Two novel ascomycetous yeast species, Saturnispora serradocipensis and Saturnispora gosingensis, were isolated from leaf detritus in a tropical stream of Southeastern Brazil and a mushroom collected in Taiwan, respectively. Analysis of the D1/D2 domains of the large-subunit of the rRNA gene of these strains showed that these species are related to Saturnispora hagleri, their closest relative. Saturnispora serradocipensis and S. gosingensis differed from S. hagleri, respectively, by seven nucleotide substitutions and two indels and three nucleotide substitutions and three indels in D1/D2 rRNA sequences. The two new species differ from each another by four nucleotide substitutions and one indel in D1/D2 rRNA sequences. However, the ITS sequences of S. serradocipensis, S. gosingensis and S. hagleri were quite divergent, showing that they are genetically separate species. The type strain of S. serradocipensis is UFMG-DC-198(T) (=CBS 11756(T) = NRRL Y-48717(T)), and of S. gosingensis GA4M05(T) is (CBS 11755(T) = NRRL Y-48718(T)).
两个新的曲霉酵母种， Saturnispora serradocipensis 和 Saturnispora gosingensis，分别从巴西东南部热带溪流中的叶碎屑和台湾采集的蘑菇中分离出来。对这些菌株大亚基 rRNA 基因的 D1/D2 区的分析表明，这些种与 Saturnispora hagleri 密切相关，是其最接近的亲缘关系。Saturnispora serradocipensis 和 S. gosingensis 与 S. hagleri 的 D1/D2 rRNA 序列分别有 7 个核苷酸替换和 2 个插入缺失以及 3 个核苷酸替换和 3 个插入缺失。这两个新种在 D1/D2 rRNA 序列中也有 4 个核苷酸替换和 1 个插入缺失的差异。然而，Saturnispora serradocipensis、S. gosingensis 和 S. hagleri 的 ITS 序列差异很大，表明它们是遗传上独立的物种。Saturnispora serradocipensis 的模式株是 UFMG-DC-198(T)=CBS 11756(T)=NRRL Y-48717(T)，而 Saturnispora gosingensis GA4M05(T)是 CBS 11755(T)=NRRL Y-48718(T)。
