    Notes:
    • Emendation accompanied by the proposal of 1 new species in the genus.
    • The e-mail address of the corresponding author given in the associated publication is not functional any more.
    • The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. See the ((text/phylogenetic-inference#the-role-of-phylogenies-in-taxonomic-classification==LPSN phylogeny page)) for details.
    • According to Hiraishi et al. 2000 [1], "phenotypic, chemotaxonomic and phylogenetic data" (i.e., phenotypic data including chemotaxonomic data, as well as sequence data) confirm that the genus Blastomonas is distinct from the genus Sphingomonas Yabuuchi et al. 1990 and other genera of the α-4 group of the α-Proteobacteria. These data turn down the proposal of Yabuuchi et al. 1999 [2, 3] for transfer of Blastomonas natatoria and Erythromonas ursincola Yurkov et al. 1997 to the genus Sphingomonas.
