I have exactly the same female. Purchased it as T. Violaceus to recently find out (once I start looking for a male for her) that this is T. Cupreus not T. Violaceus. Look at the link I have attached above . On the bottom of that post there are pictures of those 2 species. They look very similar but are 2 different species.
@Ella1984 well I purchased these from the breeder and now that I have went through a ton o photos the one thing I'm sure of is that photo I.d. isn't reliable. some of the violaceus look way darker than mine and blue and some look super purple and the same goes for shots of the Tapinauchenius cupreus. I'm not going to change labels unless I can secure a more accurate way of i.ding
