New yeasts in the Pichia guilliermondii clade were isolated from the digestive tract of basidiocarp-feeding members of seven families of Coleoptera. A molecular phylogeny and unique traits placed eight isolates in Candida fermentati and three undescribed taxa in the genus Candida. The new species and type strains are C. smithsonii (type strain NRRL Y-27642T), C. athensensis (type strain NRRL Y-27644T), and C. elateridarum (type strain NRRL Y-27647T). Based on comparison of small-and large-subunit rDNA sequences, C. smithsonii and C. athensensis form a statistically well-supported subclade with P. guilliermondii, C. xestobii, and C. fermentati; C. elateridarum is basal to this subclade.
从鞘翅目七个科的以担子果为食的成员的消化道中分离出了季也蒙毕赤酵母分支中的新型酵母。分子系统发育和独特特征将八个分离株归入发酵假丝酵母，三个未描述的分类单元归入假丝酵母属。新物种和模式菌株分别是史密森尼假丝酵母（模式菌株NRRL Y-27642T）、雅典假丝酵母（模式菌株NRRL Y-27644T）和叩头虫假丝酵母（模式菌株NRRL Y-27647T）。基于小亚基和大亚基rDNA序列的比较，史密森尼假丝酵母和雅典假丝酵母与季也蒙毕赤酵母、西氏假丝酵母和发酵假丝酵母形成了一个统计学上支持良好的亚分支；叩头虫假丝酵母位于该亚分支的基部。
