I believed it is based on her pattern and the fact that none of their males ever tried to amplex her during the 5 years they had her. I think the pattern is "different"( more spotted than blotched), but other than that and the pattern around her eyes she seems like a laevis to me. What I thought was an orange tint on her belly seems to be common among the 3 newbies and is faint enough to dismiss it.
