A Gram-stain negative, non-motile, non-phototrophic, non-alkaliphilic, obligately aerobic, chemoheterotrophic, and rod-shaped bacterium, designated strain Ma-11ᵀ, was isolated from the culture broth of a marine microalga, Picochloruma sp. 122. Phylogenetic analyses showed that strain Ma-11ᵀhas less than 91 % similarity to its closest relative, Thioalkalivibrio sulfidiphilus HL-EbGR7ᵀ, represents a distinct phylogenetic lineage in the order Chromatiales, and could not be assigned to any defined families in this order. Chemotaxonomic, genetic and physiological characteristics, including major fatty acids, genomic G+C content, lack of motility, aerophilicity and chemoheterotrophicity, could readily distinguish strain Ma-11ᵀfrom any established members of the order Chromatiales. Based on the 16S rRNA gene sequence analysis and its signature nucleotide pattern, a new family Wenzhouxiangellaceae fam. nov. comprising the genus Wenzhouxiangella gen. nov. and species Wenzhouxiangella marina sp. nov. is proposed. The type strain is Ma-11ᵀ(=CGMCC 1.14936ᵀ = KCTC 42284ᵀ = MCCC 1K00261ᵀ).
