Three strains representing a novel yeast species, Sugiyamaella xiaguanensis f.a., sp. nov. (type strain NYNU 161041(T)=CICC 33167(T)=CBS 14696(T)), were isolated from rotting wood samples collected in Henan and Yunnan Provinces, PR China. The novel species is able to assimilate cellobiose, salicin and D-xylose, which was typical of the species of the genus Sugiyamaella. Analysis of the D1/D2 domains of the large subunit rRNA gene and internal transcribed spacer regions of these strains showed that this species was related to Sugiyamaella lignohabitans and Sugiyamaella marionensis, its closest relatives. Su. xiaguanensis sp. nov. differed by 1.4 % nucleotide substitutions from Su. lignohabitans, and by 1.9 % nucleotide substitutions from Su. marionensis in the D1/D2 sequences. The ITS sequences of Su. xiaguanensis sp. nov. displayed more than 6.5 % nucleotide substitutions from the latter two species, showing that it is a genetically separate species.
