A novel basidiomycetous yeast was isolated from the waste deposit of the attine ant Acromyrmex lundii (Hymenoptera: Formicidae). The field colony was located in Santurce town, Santa Fe province, Argentina. The description of the novel species was based on strain LLU043T. Analysis of the D1/D2 domains of the LSU rRNA gene sequences in GenBank demonstrated that strain LLU043T, belongs to the Rhodosporidiobolus clade and is closely related to Rhodosporidiobolus lusitaniae and Rhodosporidioboluscolostri with 97 % similarity to the two species. The novel species differs from R. lusitaniae and R. colostri in some physiological characteristics such as the lack of assimilation of cellobiose, salicin, succinate, citrate and ethylamine. The name Rhodosporidiobolus geoffroeae sp. nov. is proposed, with LLU043T (=CBS 12828T=CBMAI 1618T) as the type strain.
从伦氏顶切叶蚁（膜翅目：蚁科）的废弃物堆积物中分离出一种新型担子菌酵母。该野外蚁群位于阿根廷圣菲省桑图尔塞镇。新物种的描述基于菌株LLU043T。对GenBank中LSU rRNA基因序列的D1/D2结构域分析表明，菌株LLU043T属于红酵母属分支，与葡萄牙红酵母和科洛斯特红酵母密切相关，与这两个物种的相似度为97%。新物种在一些生理特征上与葡萄牙红酵母和科洛斯特红酵母不同，如不能同化纤维二糖、水杨苷、琥珀酸盐、柠檬酸盐和乙胺。提出了新物种Geoffroe红酵母（Rhodosporidiobolus geoffroeae sp. nov.），以LLU043T（=CBS 12828T=CBMAI 1618T）作为模式菌株。
