Two strains of a basidiomycetous yeast were derived from an insect trypanosomatid culture isolated from the intestine of a plant bug, (Heteroptera: Miridae), collected in Costa Rica. The yeast did not form ballistoconidia but reproduced only by budding. Teliospores were not observed in individual and crossed cultures of each strain. Morphological and other taxonomic characteristics of the yeast were similar to those of the species in the polyphyletic genus . However, molecular phylogeny inferred from the internal transcribed spacers and D1/D2 region of the large subunit rRNA gene showed that the strains represent a new species placed among the smut fungi in the family Ustilentylomataceae, which includes , , , and . Given the well distinguished phylogenetic position of this novel species within the Ustilentylomataceae, we propose gen. nov., sp. nov. to accommodate the yeast isolated from , with strain American Type Culture Collection MYA-4666(T) (= PRA303-1S = CBS 12537) designated as the type strain.
