Abstract

Sixteen yeast isolates representing two novel species of the genus were obtained from passalid beetles, their galleries and rotting wood collected in three sites of Amazonian Forest in Brazil. Sequence analyses of the ITS-5.8S region and the D1/D2 domains of the large subunit rRNA gene showed that the first species, described here as f. a., sp. nov. (holotype CBS 18112, MycoBank 847461) is phylogenetically related to with these species differing by 37 nucleotide substitutions and six gaps in D1/D2 sequences. is represented by nine isolates obtained from the guts of the passalid beetles , , and , a beetle gallery and rotting wood. The second species, f. a., sp. nov. (holotype CBS 18148, MycoBank 847463), is most phylogenetically related to several undescribed species. is described based on seven isolates obtained from the guts of and , a beetle gallery and rotting wood. Both species appear to be associated with passalid beetles and their ecological niches in Amazonian biome.

摘要

从巴西亚马逊森林三个地点采集的朽木甲、其虫道和腐烂木材中获得了16株酵母分离株，它们代表了该属的两个新物种。对ITS-5.8S区域和大亚基rRNA基因的D1/D2结构域进行序列分析表明，第一个物种在此被描述为f. a.，sp. nov.（模式菌株CBS 18112，MycoBank 847461），在系统发育上与相关，这些物种在D1/D2序列上有37个核苷酸替换和6个缺口。由从朽木甲、、和的肠道、一个虫道和腐烂木材中获得的9个分离株代表。第二个物种，f. a.，sp. nov.（模式菌株CBS 18148，MycoBank 847463），在系统发育上与几个未描述的物种关系最为密切。基于从和的肠道、一个虫道和腐烂木材中获得的7个分离株对其进行了描述。这两个物种似乎都与亚马逊生物群落中的朽木甲及其生态位有关。
