We extend the recently developed treatment of baryon resonances in large Nc QCD to describe resonance multiplets collected according to the SU(3) flavor symmetry that includes strange quarks. As an illustration we enumerate the SU(3) partners of a hypothetical JP=1/2 ± resonance in the SU(3) representation that reduces to 10 when Nc=3, and reproduce results hitherto obtained only in the context of a large Nc quark picture. While these specific quantum numbers represent one favored set for the possible pentaquark state Θ+(1540), the method is applicable to baryon resonances with any quantum numbers.
