Three strains originating from insect frass in South Africa, yellow foxglove in Hungary and soil in France, were characterised phenotypically and by sequencing of the D1/D2 domain of the large subunit and the ITS1-5.8S-ITS2 (ITS)-region of the rRNA gene. The strains have identical D1/D2 domain sequences and only one strain shows a 1 bp indel in a 9 bp homopolymer A/T repeat within the ITS-region. Based on sequence analysis Hyphopichia burtonii is the closest related species. The investigated strains differ from the type strain of H. burtonii by 1.9% (9 substitutions and an indel) in the D1/D2 domain and by 23 substitutions and 21-22 indels in the ITS-region. Since the sequence variability is very low among the three strains and the sequence divergence with the closely related H. burtonii exceeds the level generally encountered between species we propose the new species Hyphopichia lachancei f.a., sp. nov. to accommodate the three novel strains. From H. burtonii the new species can be distinguished phenotypically by its inability to ferment cellobiose and by the formation of endospores (Holotype: CBS 5999T; Isotype: NCAIM Y.02228T; MycoBank no.: MB833616).

Hychopichia lachancei，fa，sp。十一月，来自不同来源的酵母物种。

表型和通过对大亚基的D1 / D2结构域和ITS1-5.8S-ITS2（ITS）区域进行测序，表征了源自南非昆虫的三株菌株，匈牙利的黄色毛地黄手套和法国的土壤。 rRNA基因。这些菌株具有相同的D1 / D2结构域序列，只有一个菌株在ITS区域内的9 bp均聚物A / T重复序列中显示1 bp indel。根据序列分析，Burphophoii burtonii是最接近的相关物种。研究的菌株与伯氏嗜血杆菌的类型菌株在D1 / D2结构域中相差1.9％（9个替换和一个indel），在ITS区中相异23个替换和21-22个indel。由于这三个菌株之间的序列变异性非常低，并且与紧密相关的H的序列差异很大。burtonii超过了物种之间通常遇到的水平，我们提出了新物种Hyphopichia lachancei fa，sp.。十一月 以适应三种新菌株。在伯氏嗜血杆菌中，该新种在表型上可以通过不能发酵纤维二糖和形成内生孢子来区分（完整型：CBS 5999T；同型：NCAIM Y.02228T； MycoBank编号：MB833616）。
