I think D. tenebrosus as well (yes, fishing spider). They like it moist. Set her up basically like an arboreal with a big water dish. Fluffy grass-like adornments in the cage would be good. They like to web stuff like that together to make a nursery web. I don't have a clear idea of how big she is but if she's an adult (2.5"+ DLS) then she could very well be carrying eggs.
