Two novel yeast species were isolated during three independent studies of yeasts associated with natural substrates in Brazil and Taiwan. Analysis of the sequences of the D1/D2 domains of the large subunit rRNA gene showed that these novel species belong to the clade. The first was isolated from freshwater and a leaf of sugar cane () in Brazil and from leaves of in Taiwan. Described here as sp. nov., it differs by 56 nucleotide substitutions and 19 gaps in the D1/D2 region of the large subunit rRNA gene from , the least divergent species. The second species, named sp. nov., was isolated from leaves and the rhizosphere of sugar cane collected in Rio de Janeiro, Brazil. The species differs by 54 nucleotide substitutions and nine gaps in the D1/D2 domains from , its least divergent relative. The type strains are sp. nov. IMUFRJ 52096 ( = CBS 12417 = DBVPG 8032) and sp. nov. IMUFRJ 52102 ( = CBS 12419 = DBVPG 8034).
