Comparison of the D1/D2 domain of the large subunit (LSU D1/D2) rRNA gene sequences of CLIB 1634T and CLIB 1707T to those in the GenBank database revealed that these strains belong to the Starmerella clade. Strain CLIB 1634T was shown to diverge from the closely related Starmerella apicola type strain CBS 2868T with a sequence divergence of 1.34 and 1.30 %, in the LSU D1/D2 rRNA gene and internal transcribed spacer (ITS) sequences respectively. Strain CLIB 1634T and Candida apicola CBS 2868T diverged by 3.81 and 14.96 % at the level of the protein-coding gene partial sequences EF-1α and RPB2, respectively. CLIB 1707T was found to have sequence divergence of 3.88 and 9.16 % in the LSU D1/D2 rRNA gene and ITS, respectively, from that of the most closely related species Starmerella ratchasimensis type strain CBS 10611T. The species Starmerella reginensis f.a., sp. nov. and Starmerella kourouensis f.a., sp. nov. are proposed to accommodate strains CLIB 1634T (=CBS 15247T) and CLIB 1707T (=CBS 15257T), respectively.
The GenBank/EMBL/DDBJ accession numbers for the D1/D2 region of the LSU rRNA gene and ITS sequences determined in this study are, for CLIB 1634T and CLIB 1707T, LN870357/LN870338 and LN909483/LN909469; for the sequences EF1-α and RPB2 for CLIB 1634T and CBS 2868T, MG428400/MG428402 and MG428401/MG428403. The Mycobank accession numbers for Starmerella reginensis f.a., sp. nov. and Starmerella kourouensis f.a., sp. nov. are MB 823343 and MB 823344, respectively.
