A novel yeast species was found repeatedly and in high cell densities in underground-nesting stingless bees of the species Melipona quinquefasciata and their provisions in northern Minas Gerais (Brazil). One additional strain was isolated from bee-collected pollen in Cuba. Phylogenetic analyses based on rRNA gene sequences (D1/D2 large subunit gene and internal transcribed spacer) indicated that the novel species belongs to the Starmerella clade and is most closely related to Candida (iter. nom. Starmerella) apicola. Growth reactions on carbon and nitrogen sources were typical of those observed in related species of the Starmerella clade. PCR-fingerprinting with mini- and microsatellite specific primers allowed the distinction of the novel species from Candida apicola, Candida bombi and a yet undescribed species represented by strain CBS 4353. On the basis of phylogenetic relationships, the novel species is assigned to the genus Starmerella despite the failure to observe sexual reproduction after extensive mating tests. We propose the name Starmerella neotropicalis f. a., sp. nov. (Mycobank MB 804285) and designate UFMG PST 09T ( = MUCL 53320T = CBS 12811T) as the type strain.
