Two extremely halophilic archaea strains, CBA1112^T and CBA1113, were isolated from solar salt in Korea. The genome sizes and G + C content of CBA1112^T and CBA1113 were 3.77 and 3.53 Mb, and 66.0 and 66.5 mol%, respectively. Phylogenetic analysis based on closely related taxa and environmental Haloplanus sequences indicated that both CBA1112^T and CBA1113 strains are grouped within the genus Haloplanus. OrthoANI and in silico DNA–DNA hybridization values were below the species delineation threshold. Pan-genomic analysis showed that the two novel strains and four reference strains had 6203 pan-orthologous groups in total. Six Haloplanus strains shared 1728 core pan-genome orthologous groups, which were mainly associated with amino acid transport and metabolism and translation, ribosomal structure and biogenesis categories, and amino acid metabolism and carbohydrate metabolism related categories. The novel strain-specific pan-genome orthologous groups were mainly involved with replication, recombination and repair category and replication and repair pathway or amino acid metabolism pathway. Cells of both strains were Gram-negative and pleomorphic, and colonies were red-pigmented. The major polar lipids of both strains were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate, and one glycolipid, sulfated mannosyl glucosyl diether. Based on genomic, phylogenetic, phenotypic, and chemotaxonomic features, strains CBA1112^T and CBA1113 are described as novel species of the genus Haloplanus. Thus, we propose the name Haloplanus rubicundus sp. nov. The type strain is CBA1112^T (=KCCM 43224^T = JCM 30475^T).

在韩国，从太阳盐中分离出两种极端嗜盐古生菌菌株CBA1112 ^T和CBA1113。CBA1112 ^T和CBA1113的基因组大小和G + C含量分别为3.77和3.53 Mb，以及66.0和66.5 mol％。根据密切相关的分类单元和环境Haloplanus序列的系统发育分析表明，CBA1112 ^T和CBA1113菌株都归入Haloplanus属。OrthoANI和计算机DNA-DNA杂交值低于物种划分阈值。泛基因组分析表明，两个新菌株和四个参考菌株总共具有6203个泛直系同源群。六个晕轮这些菌株共有1728个核心全基因组直系同源组，主要与氨基酸运输和代谢与翻译，核糖体结构和生物发生类别以及氨基酸代谢和碳水化合物代谢相关类别有关。新的菌株特异性泛基因组直系同源基团主要涉及复制，重组和修复类别以及复制和修复途径或氨基酸代谢途径。两种菌株的细胞均为革兰氏阴性和多形性，菌落为红色。两种菌株的主要极性脂质为磷脂酰甘油，磷脂酰甘油磷酸甲酯，磷脂酰甘油硫酸盐和一种糖脂，硫酸化的甘露糖基葡糖基二醚。根据基因组，系统发育，表型和化学分类学特征，菌株CBA1112^T和CBA1113被描述为Haloplanus属的新物种。因此，我们建议使用名称Haloplanus rubicundus sp。十一月 模式菌株是CBA1112 ^Ť（= KCCM 43224 ^Ť  = JCM 30475 ^Ť）。
