Three new beetle-associated yeast species in the Pichia guilliermondii clade

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
