  The Southern Hemisphere has just recently begun to be charted by wide-field
surveys, with a sufficient depth and image quality to enable the discovery of
strongly lensed quasars. The quadruply imaged quasar WG0214-2105
(r.a.=02:14:16.37, dec.=-21:05:35.3) is a previously unknown lens, with `blue'
mid-IR colors and high UV deficit, found in the intersection of three survey
footprints: the Dark Energy Survey public DR1 (DES, Abbott et al. 2018), The
VST-ATLAS (Shanks et al. 2015) and Pan-STARRS (Chambers et al. 2016). Its
discovery relied on high spatial resolution from the Gaia mission (Lindegren et
al. 2016) and mid-IR color preselection in the WISE catalog (Wright et al.
2010).
