Conteúdo: 	Previous studies have recognized South and Central/Latin American mimosoid legumes in the generaMimosa, Piptadenia and Calliandra as hosts for various nodulating Paraburkholderia species. Several ofthese species have been validly named in the last two decades, e.g., P. nodosa, P. phymatum, P. diazotroph-ica, P. piptadeniae, P. ribeironis, P. sabiae and P. mimosarum. There are still, however, a number of diverseParaburkholderia strains associated with these legumes that have an unclear taxonomic status. In thisstudy, we focus on 30 of these strains which originate from the root nodules of Brazilian and MexicanMimosa species. They were initially identified as P. tuberum and subsequently placed into a symbiovar(sv. mimosae) based on their host preferences. A polyphasic approach for the delineation of these strainswas used, consisting of genealogical concordance analysis (using atpD, gyrB, acnA, pab and 16S rRNA genesequences), together with comparisons of Average Nucleotide Identity (ANI), DNA G + C content ratiosand phenotypic characteristics with those of the type strains of validly named Paraburkholderia species.Accordingly, these 30 strains were delineated into two distinct groups, of which one is conspecific with?P. atlantica? CNPSo 3155Tand the other new to Science. We propose the name Paraburkholderia youngiisp. nov. with type strain JPY169T(= LMG 31411T; SARCC751T) for this novel species
