Five yeast isolates belonging to a candidate for novel species were obtained from rotting wood and the gut of a passalid beetle larva in a site of Amazonian rainforest biome in Brazil. Sequence analysis of the Internal Transcribed Spacer (ITS)-5.8S region and the D1/D2 domains of the large subunit rRNA gene showed that the isolates represent a novel species of the genusVanderwaltozyma. The closest relative of the novel species isVanderwaltozyma huisunica. These species differs due to 44 nt substitutions and 21 indels in the sequences of the ITS region, as well as by 15 substitutions and four indels in the sequences of the D1/D2 domains. A phylogenomic analysis of theVanderwaltozymaspecies with genomes sequenced showed that this novel species is an outgroup to the other species of this genus. We propose the nameVanderwaltozyma urihicolasp. nov. (CBS 18107^T, MycoBank MB 856975) to accommodate these isolates. The species is homothallic, producing one to two ascospores per ascus. The habitat ofV. urihicolais rotting wood in the Brazilian Amazonian rainforest biome.
