Not tagged as Digimon Xros Wars or Digimon Savers since the artist didn't tag it that way and there is no indication this is the Lilithmon from either, just the overall Digimon series.
Well, usually for it to be tagged for one season, it'd require one of the human characters or perhaps season-specific forms. Lilithmon herself has existed for years before Xros Wars. It's strange, though, that the digimon incarnation of lust of all things has so little art for her...
