Four yeast strains were isolated from rotting wood samples collected in the Baotianman Nature Reserve in Henan Province, central China. The sequences of the D1/D2 domains of the large subunit rRNA gene and the internal transcribed spacer regions showed that these four strains represent two different undescribed yeast species belonging to the Ogataea clade. Ogataea neixiangensis sp. nov. produces two to four hat-shaped ascospores per ascus, and its closest relative among recognized species is Candida nitratophila. Ogataea paraovalis f.a., sp. nov. is closely related to Candida ovalis but the formation of ascospores was not observed on various sporulation media. The type strain of O. neixiangensis sp. nov. (MycoBank number MB 820697) is NYNU 16951T (=CICC 33166T=CBS 14695T), and the type strain of O. paraovalis f.a., sp. nov. (MycoBank number MB 820698) is NYNU 167106T (=CICC 33168T=CBS 14697T).
从中国中部河南省宝天曼自然保护区采集的腐烂木材样本中分离出四株酵母菌株。大亚基rRNA基因的D1/D2结构域和内部转录间隔区的序列表明，这四株菌株代表了属于Ogataea分支的两个未描述的不同酵母物种。内乡Ogataea菌新种每个子囊产生两到四个帽形子囊孢子，在已确认的物种中其最接近的亲缘种是嗜硝酸盐假丝酵母。类卵形Ogataea菌新变种与卵形假丝酵母密切相关，但在各种产孢培养基上均未观察到子囊孢子的形成。内乡Ogataea菌新种的模式菌株（国际真菌名称索引编号MB 820697）是NYNU 16951T（=中国工业微生物菌种保藏管理中心33166T=荷兰CBS菌种保藏中心14695T），类卵形Ogataea菌新变种的模式菌株（国际真菌名称索引编号MB 820698）是NYNU 167106T（=中国工业微生物菌种保藏管理中心33168T=荷兰CBS菌种保藏中心14697T）。
