Strain J-MS1T was found to grow optimally at 30 °C and pH 7.0–8.0. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain J-MS1T belonged to the genus Rheinheimera , clustering coherently with the type strain of Rheinheimera chironomi and sharing 98.34 % sequence similarity. Strain J-MS1T exhibited 16S rRNA gene sequence similarity of 94.26–96.98 % to the type strains of the other species of the genus Rheinheimera . In the phylogenetic trees based on gyrB sequences, strain J-MS1T clustered with the type strain of R. chironomi , with which it shared the highest sequence similarity (86.97 %). Strain J-MS1T contained Q-8 as the predominant ubiquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c as the major fatty acids. The major polar lipids detected in strain J-MS1T and in the type strain of R. chironomi were phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content of strain J-MS1T was 49.8 mol% and its mean DNA–DNA relatedness value with R. chironomi LMG 23818T was 12 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain J-MS1T is separated from recognized species of the genus Rheinheimera . On the basis of the data presented, strain J-MS1T is considered to represent a novel species of the genus Rheinheimera , for which the name Rheinheimera arenilitoris sp. nov. is proposed. The type strain is J-MS1T ( = KCTC 42112T = CECT 8623T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.067504-0
