Abstract

Five yeast strains were isolated from the gut of the groundbeetle and rotting wood, which were collected from two different localities in China. These strains were identified as representing two novel species of the genus through comparison of sequences in the D1/D2 domains of the LSU rRNA gene and other taxonomic characteristics. sp. nov. produces two to three spherical ascospores per ascus, and is most closely related to the type strains of , , , and an undescribed species represented by strain BG02-7-20-006A-3-1. sp. nov. differed from these strains by 3.6–8.4 % divergence (21–46 substitutions and 0–4 gaps) in the D1/D2 sequences. f.a., sp. nov. is closely related to , and but the formation of ascospores was not observed on various sporulation media, and it differed from its relatives by 6.2–8.5 % divergence (34–43 substitutions and 2–6 gaps) in the D1/D2 sequences. The holotype of sp. nov. is NYNU 1581 and the holotype of f.a., sp. nov. is NYNU 181030.
