We report the serendipitous discovery of a quadruply-lensed source behind the\nz=0.095 edge-on disk galaxy 2MASXJ13170000-1405187, based on public imaging\nsurvey data from Pan-STARRS PS1 and the VISTA Hemisphere Survey. Follow-up\nimaging from Magellan/LDSS3 shows that the background source is spatially\nextended (i.e. not a QSO), and that two of the lensed images are observed\nthrough a prominent dust ring in the disk of the lens galaxy. We summarise\nresults of preliminary modelling, which indicates an Einstein radius of 1.44\narcsec, and a K-band mass-to-light ratio of 0.5, relative to the solar value.\n
