A Gram-stain-negative, non-motile, aerobic, curved-to-spiral-rod-shaped bacterium, designated AH-MY2T, was isolated from a tidal flat on Aphae island in the sea to the south-west of South Korea, and its taxonomic position was investigated using a polyphasic taxonomic approach. Strain AH-MY2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain AH-MY2T clustered with the type strain of Terasakiella pusilla and that this cluster joined the clade comprising the type strains of species of the genus Thalassospira . Strain AH-MY2T exhibited 16S rRNA gene sequence similarity values of 90.6 % to the type strain of Terasakiella pusilla and of less than 91.0 % to the type strains of other species with validly published names. Strain AH-MY2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids detected in strain AH-MY2T were phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminolipids and one unidentified glycolipid. The DNA G+C content of strain AH-MY2T was 56.0 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain AH-MY2T represented a novel genus and species within the family Rhodospirillaceae of the class Alphaproteobacteria , for which the name Aestuariispira insulae gen. nov., sp. nov. is proposed. The type strain of Aestuariispira insulae is AH-MY2T ( = KCTC 32577T = CECT 8488T).
