Abstract

Three species of Scheffersomyces were identified during a diversity study of yeasts. All three are associated with insects and rotting wood in China. Phylogenetic analyses of a genomic dataset combining ITS and nrLSU revealed that these new collections are distinct from known species, thus three new species are introduced i.e. S. jinghongensis, S. paraergatensis, and S. anoplophorae. In our phylogenetic analyses, Scheffersomyces jinghongensis possesses a strong independent lineage and is closely related to S. titanus. S. paraergatensis is closely related to S. ergatensis, while S. anoplophorae is related to S. stambukii. Several differences in physiological traits and molecular data indicate that S. jinghongensis, S. paraergatensis, and S. anoplophorae are three newly identified species.
