Abstract

Eleven yeast strains representing four novel species of the genus were isolated from scarabs beetles collected in Nanyang, Henan Province, Central China. Phylogenetic analysis using combined sequences of the D1/D2 domains of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) regions placed all the novel species in a clade distinct from the other known species in the clade representing the members of the genus . These novel species differed from each other or their closest known species by more than 4.9 % nucleotide substitutions in the D1/D2 domains and by more than 9.1 % nucleotide substitutions in the ITS regions. The four novel species can also be separated from their closest relatives in terms of physiological characteristics. No asci or signs of conjugation were found in the novel species on the most common sporulation media. The novel species are designated as f.a., sp. nov. (type strain NYNU 157145=CICC 33094=CBS 14178), f.a., sp. nov. (type strain NYNU 15782=CICC 33089=CBS 14173), f.a., sp. nov. (type strain NYNU 15766=CICC 33088=CBS 14172) and f.a., sp. nov. (type strain NYNU 15821=CICC 33090=CBS 14174).
