Three yeast strains designated as S44, XF1 and XF2, respectively, were isolated from
Scolytus scheryrewi
Semenov of apricot tree in Shule County, Xinjiang, China, and were demonstrated to be a new member of the genus
Candida
by sequence comparisons of 26S rRNA gene D1/D2 domain and internal transcribed spacer (ITS) region. BLASTn alignments on NCBI showed that the similarity of 26S rRNA gene sequences of S44 (type strain) to all sequences of other
Candida
yeasts was very low (≦93 %). The phylogenetic tree based on the 26S rRNA gene D1/D2 domain and ITS region sequences revealed that the strain S44 is closely related to
C. blattae
,
C. dosseyi
,
C. pruni
,
C. asparagi
,
C. fructus
and
C. musae
. However, the strain S44 is distinguished from these
Candida
species by the physiological characteristics. Moreover, the strain S44 formed typical pseudohyphae when grown on cornmeal agar at 25 °C for 7 days, but did not form ascospores in sporulation medium for 3–4 weeks. Therefore, the name
Candida xinjiangensis
is proposed for the novel species, with S44 (=KCTC
T
27747) as the type strain.
