I think currently any natural hybrid collected from the wild are called x wenshanense and any crosses made in the lab. are called Conco-bellatulum. However, if some one try to self any plants from wild origin will remain wenshanense. The shape usually look the same as bellatulum, but the color range from white to pale yellow. I had seen good clones of conco-bellatulum and they have yellow color as deep as concolor.
It looks like a wenshanense to me. In fact, I agree that wenshanense is a seperate species as I've never seen a man-made conco-bellatulum that looks anything like a wenshanense. The only way I think wenshanense could be a natural hybrid is from thousands of years or more of evolution (sibs between the x wenshanense).
Come to think of it.. wenshanese seems to come in a white or yellow-ish white background with similar spotting on a flat finish. Your plant looks to be a little more waxy to me, so perhaps it is a conco-bellatulum or similar hybrid.
