Abstract

14 different yeasts were isolated from the gut of a variety of insects, including beetles, lacewings, fishflies, craneflies, and a cockroach. One of the yeasts was found both in the gut and on the body surface of a beetle larva. Based on ribosomal DNA sequence comparisons and phenotypic characters, the yeasts were identified as Candida membranifaciens, C. tenuis, Pichia nakazawae, and nine undescribed taxa in Saccharomycotina. All the undescribed taxa reproduced only asexually, and they fit within the limits of the polyphyletic genus Candida. The new species and their type strains are Candida blattariae NRRL Y-27703T, C. amphixiae NRRL Y-27704T, C. michaelii NRRL Y-27705T, C. cerambycidarum NRRL Y-27706T, C. gorgasii NRRL Y-27707T, C. endomychidarum NRRL Y-27708T, C. temnochilae NRRL Y-27763T, C. sinolaborantium NRRL Y-27765T, and C. lessepsii NRRL Y-27766T spp. nov. Phylogenetic analysis of combined small and large subunit ribosomal DNA sequences placed C. amphixiae, C. michaelii, C. cerambycidarum, C. gorgasii, C. endomychidarum, and C. lessepsii in a statistically well supported clade with C. blattariae, C. membranifaciens, C. friedrichii, and C. buinensis as sisters to the clade. The other two new taxa, C. temnochilae and C. sinolaborantium, formed an independent clade basal to the major clade containing C. membranifaciens and closely related taxa. C. sinolaborantium occurred in both Panama and the USA, but there were genetic differences between the isolates from the two places.
