Abstract: The genus Kloeckeraspora Niehaus (1932) was not accepted for a long time. This paper has tried to reinstate the genus. Two phylogenetic trees were constructed for three Kloeckeraspora and four representative Hanseniaspora species. In addition, the pair-wise sequence similarities were calculated. In the phylogeneetic tree based on the 26S rRNA gene D1/D2 domain sequences derived from the neighbour-joining method, the three species of the genus Kloeckeraspora represented an extremely long branch. The calculated pair-wise sequence similarities were abnormally low (86.2 - 88.5%) between the two genera. Incidentally, the sequence similarity between Vanderwatozyma polyspora and Saccharomyces cerevisiae used as references was 94.0%. The genus Kloeckeraspora should be unequivocally accepted and retained. However, the two genera were not yet perfectly taxonomic homogeneous-natured.
