  We report the discovery of a circular mid-infrared shell around the
emission-line star Wray 16-137 using archival data of the Spitzer Space
Telescope. Follow-up optical spectroscopy of Wray 16-137 with the Southern
African Large Telescope revealed a rich emission spectrum typical of the
classical luminous blue variables (LBVs) like P Cygni. Subsequent spectroscopic
and photometric observations showed drastic changes in the spectrum and
brightness during the last three years, meaning that Wray 16-137 currently
undergoes an S Dor-like outburst. Namely, we found that the star has brightened
by \approx 1 mag in the V and I_c bands, while its spectrum became dominated by
Fe ii lines. Taken together, our observations unambiguously show that Wray
16-137 is a new member of the family of Galactic bona fide LBVs.
