Songthela (sp) china

We have this trapdoor spider as Songthela sp. found in china. It's a female, we don't know more. So far we could not assign the 8-legged friend. Is it a different species and the dealer made up a name? Is it a new species? We do not know it. If you recognize the animal and have information, please write to us! The body length is currently almost exactly 2 cm.
