gen. nov., sp. nov., a yeast species in the Saccharomycetales and reassignment of to the genus .

Two yeast strains, DMKU-WBL1-3 and DMKU GT3-16, were obtained from grease samples collected from grease traps at the Kasetsart University canteen, Thailand. Pairwise sequence analysis indicated that the strains were closely related to NRRL Y-17506, but differed by 11 and 35 nucleotide substitutions in the D1/D2 domain of the large subunit (LSU) rRNA gene and the ITS region, respectively. Based on sequence divergences, the novel species was distinguished from . The results of phylogenetic analysis based on the concatenated sequences from small subunit rRNA, ITS region and LSU rRNA genes showed that the two strains and NRRL Y-17506 formed a distinct lineage related to the genus . A novel genus, , is proposed to accommodate these clade members. Hence, NRRL Y-17506 is transferred to this genus and assigned as the type species of the genus. The holotype of is DMKU-WBL1-3.
