Using the approximate flavor SU(3) symmetry of strong interactions, we argue for the existence of a new Lambda baryon with J^P=3/2^-, the mass around 1850 MeV, the total width of about 130 MeV, significant branching into the Sigma \pi and Sigma^{\ast} \pi states and a vanishingly small coupling to the N {\bar K} state. This confirms quark model predictions suggesting a new Lambda baryon in the mass range between 1775 MeV and 1880 MeV with a very small coupling to the N {\bar K} state.
