abstract= Five new yeast species, Wickerhamiella australiensis, Wickerhamiella cacticola, Wickerhamiella occidentalis, Candida drosophilae and Candida lipophila, are described to accommodate isolates recovered from flowers and floricolous insects of Australian Hibiscus trees, cosmopolitan morning glories (Ipomoea spp.) and Brazilian cereoid cacti. The new Wickerhamiella species are heterothallic, occur in the haploid condition and are clearly separated reproductively from one another. Although they exhibit little physiological variation, they are easily delineated from Wickerhamiella domercqiae, the only species known previously, by their resistance to cycloheximide and the production of strong extracellular lipases. C. drosophilae and C. lipophila share the latter property, but unlike the Wickerhamiella species, they fail to utilize nitrate as sole nitrogen source. PFGE indicates that these yeasts have an unusually low number of chromosomes. The large-subunit rDNA (D1/D2) sequences demonstrate a close relationship between the five species and Candida vanderwaltii and Candida azyma. Their relationship with W. domercqiae is more distant, but all share, with some other Candida species, a single monophyletic clade. The type and isotype strains are as follows: W. australiensis strains UWO(PS)95–604.3T(h+; CBS 8456T) and UWO(PS)95–631.31(h+; CBS 84571); W. cacticola strains UFMG96–267T(h+; CBS 84540 and UFMG96–3811(h-; CBS 84551); W. occidentalis strains UWO(PS)91–698.4T(h+; CBS 8452T) and UFMG96–2121 (h-; CBS 84531); C. drosophilae UWO(PS)91–716.3T(CBS 8459T); and C. lipophila UWO(PS)91–681.3T(CBS 8458T).,
