The phylogenetic positions of the type strain and strain A62 of [Pseudomonas] lemoignei, as well as those of nine bacterial isolates closely related to [Pseudomonas] lemoignei, were re-evaluated by analysing morphological, physiological and molecular-biological characteristics. 16S rDNA analysis confirmed that the type strain of [Pseudomonas] lemoignei and strain A62 belong to the order 'Burkholderiales' of the beta-Proteobacteria and represent a new cluster, for which the name Paucimonas gen. nov. is proposed. Paucimonas contains a single species, Paucimonas lemoignei comb. nov.
