Abstract

Five strains representing a novel yeast species belonging to the genus were independently isolated from Ecuador, Taiwan and the USA. One strain (CLQCA 10-161) was isolated from the white flower of an unidentified plant species collected in the Maquipucuna cloud forest reserve, near Quito, in Ecuador. A second strain (GY7L12) was isolated from the leaf of a Chinese sumac or nutgall tree (’) collected in the Taoyuan mountain area, Kachsiung, in Taiwan. Three additional strains (A543, A546 and A563) were isolated from two species of wood-boring beetle ( and ) collected near Clyo, Georgia, USA. Analysis of the D1/D2 domains of the LSU rRNA gene indicated that the novel species belongs to the genus , and is most closely related to an insect-associated species predominantly found in South Africa. The North American and Taiwanese strains have identical internal transcribed spacer (ITS) sequences and can be distinguished from the Ecuadorian strain based on a single nucleotide substitution in the ITS1 region. The species name of f.a., sp. nov. is proposed to accommodate these strains, with CLQCA 10-161 ( = CBS 12941 = NCYC 3743) designated the type strain.
