Abstract: Three strains of novel oleaginous yeast species were isolated from soil samples collected in Shiga Prefecture, Japan. The sequences of the internal transcribed spacer (ITS) region and the D1/D2 region of the large subunit (LSU) of the rRNA genes indicated that these novel yeast species are members of the genus Hannaella. The results of molecular phylogenetic analysis indicated that strains 38–3 and 8s1 were closely related to Hannaella oryzae. They differed by 10 nucleotide substitutions and one gap (1.77 %) in the D1/D2 region of the LSU of the rRNA genes and by 17–18 nucleotide substitutions and 10–11 gaps (5.45–5.85 %) in the ITS region. Strain 51–4 differed from the type strain of the most closely related species, Hannaella pagnoccae, by 26 nucleotide substitutions (4.46 %) in the D1/D2 region of the LSU of the rRNA genes and by 20 nucleotide substitutions and six gaps (5.42 %) in the ITS region. The names proposed for these previously undescribed species are Hannaella oleicumulans sp. nov. and Hannaella higashiohmiensis sp. nov.
