Based on the phylogenetic, genomic and phenotypic characteristics presented in this study, we showed the existence of two novel species within the genus Pseudomonas, for which the names P. serbica (with the type strain IT!P366T) and P. serboccidentalis (with the type strain IT! P374T) are proposed. The full protologue descriptions of these novel species are presented in Tables 7 and 8.
