This article describes a new genus and species of cyanobacteria isolated from Laguna Pastos Grandes in the Bolivian Altiplano. This discovery marks the first described species of this phylum from this extreme environment. Additionally, the phylogenetic status of the genus is reassessed. The analyses are based on 16S rRNA gene maximum likelihood and Bayesian phylogenies, identity (p-distance), morphology and habitat comparisons. The new genus is a -like type from a mat at the margin of a brackish-alkaline lake with borax. It is phylogenetically close to , and , but compared to these genera, the maximum 16S rRNA gene identity values reached only 90.9%, 91.1% and 92.5%, respectively. The genus was found to be polyphyletic. The type species is clustered with . However, "" and "" form a distinct clade, distant from the type species. Between the two "" clades, and are found.
本文描述了从玻利维亚高原的大帕斯托斯湖分离出的一种新的蓝细菌属和种。这一发现标志着首次从这种极端环境中描述该门的物种。此外，还重新评估了该属的系统发育地位。分析基于16S rRNA基因最大似然法和贝叶斯系统发育、同一性（p距离）、形态学和栖息地比较。新属是一种类似的类型，来自一个含硼砂的微咸碱性湖泊边缘的席状体。它在系统发育上与、和接近，但与这些属相比，16S rRNA基因的最大同一性值分别仅达到90.9%、91.1%和92.5%。发现该属是多系的。模式种与聚集在一起。然而，“”和“”形成一个独特的分支，与模式种相距甚远。在两个“”分支之间，发现了和。
