Abstract

A major clade of new yeast taxa from the digestive tract of basidiocarp-feeding beetles is recognized based on rRNA gene sequence analyses. Almost 30 % of 650 gut isolates formed a statistically well-supported clade that included . The yeasts in the clade were isolated from 11 families of beetles, of which Tenebrionidae and Erotylidae were most commonly sampled. Repeated isolation of certain yeasts from the same beetle species at different times and places indicated strong host associations. Sexual reproduction was never observed in the yeasts. Based on comparisons of small- and large-subunit rRNA gene sequences and morphological and physiological traits, the yeasts were placed in and in 16 other undescribed taxa. In this report, the novel species in the genus are described and their relationships with other taxa in the Saccharomycetes are discussed. The novel species and their type strains are as follows: (NRRL Y-27568=CBS 9823), (NRRL Y-27571=CBS 9824), (NRRL Y-27580=CBS 9825), (NRRL Y-27573=CBS 9826), (NRRL Y-27606=CBS 9827), (NRRL Y-27574=CBS 9828), (NRRL Y-27569=CBS 9829), (NRRL Y-27566=CBS 9830), (NRRL Y-27584=CBS 9831), (NRRL Y-27587=CBS 9832), (NRRL Y-27570=CBS 9833), (NRRL Y-27567=CBS 9834), (NRRL Y-27572=CBS 9835), (NRRL Y-27588=CBS 9836), (NRRL Y-27563=CBS 9837) and (NRRL Y-27589=CBS 9838).
