Remarks :

According Patricia Perez-Garcia " I was looking your specimen and I'm not sure about the ID. It looks like Stylochidae, as you said, but this family have a very characteristic pharynx, it is more branched (I'm sure in this point). So, I don't think about Paraplanocera or another Stylochidae species. It must belong to other superfamily.
          I'm more inclined about an Ilyoplanoidea (for me, this superfamily wins for the moment in this case), or maybe a Leptoplanoidea species "
