Interpretive Summary: A diagnostic gene sequence database developed at NCAUR allows rapid identification of known yeasts as well as the detection of new species. This database was used to detect three new yeast species and to place them in their correct genera. The present study formally describes these new species. Two of the species are members of the Yarrowia clade and may have biotechnological potential because the earlier described Yarrowia lipolytica is used industrially to produce lipases and proteases as well as citric acid, which has a large number of industrial, food and beverage applications.

Technical Abstract: Three new species of Candida and a new combination in the genus Hyphopichia are proposed from phylogenetic analysis of nucleotide divergence in domains D1/D2 of large subunit (26S) rDNA. The new taxa and their type strains are the following: Candida bentonensis sp. nov. (NRRL YB-2364, CBS 9994), Candida hispaniensis sp. nov. (NRRL Y-5580, CBS 9996) Candida pseudorhagii sp. nov. (NRRL YB-2076, CBS 9998) and Hyphopichia heimii comb. nov. (NRRL Y-7502, CBS 6139), basionym Pichia heimii Pignal. Phylogenetic analysis placed C. pseudorhagii and H. heimii in the Hyphopichia clade whereas C. bentonensis and C. hispaniensis are members of the Yarrowia clade.
