Phylogenetic analysis based on 16S rRNA gene sequence similarities showed that strain 167-74T is closely related to Halostagnicola larsenii XH-48T (98.3 %) and Halostagnicola kamekurae 194-10T (97.2 %). The major polar lipids of the isolate were C20C20 and C20C25 derivatives of phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester. A glycolipid was not detected, in contrast to the two existing, neutrophilic species of the genus Halostagnicola. The DNA G+C content of strain 167-74T was 60.7 mol%. and it gave DNA–DNA reassociation values of 19.5 and 18.8 %, respectively, with Hst. larsenii JCM 13463T and Hst. kamekurae 194-10T. Therefore, strain 167-74T represents a novel species, for which the name Halostagnicola alkaliphila sp. nov. is proposed, with the type strain 167-74T ( = JCM 16592T  = CECT 7631T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.023119-0
