From the LPSN web site: "Pseudomonas ficuserectae Goto 1983, Pseudomonas amygdali Psallidas and Panagopoulos 1975 (Approved Lists 1980), Pseudomonas meliae Ogimi 1981, and Pseudomonas savastanoi (Janse 1982) Gardan et al. 1992 are members of a single genomospecies. Thus, these species should be considered synonymous and the correct name for this species should be Pseudomonas amygdali. Unfortunately, Pseudomonas amygdali, as delineated by DNA-DNA hybridization, could not be differentiated from other genomospecies by phenotypic tests. So the authors [Gardan et al. 1999] do not formally propose nomenclatural changes." [N.B.: See also Gomila M et al. (2017).]

[N.B.: Gardan et al. claim strains CFBP 1660 (pathotype of P. syringae pv. primulae) and CFBP 2348 (pathotype of P. syringae pv. ribicola) are misidentified and should be transferred to Pseudomonas viridiflava.]
