I would have thought so too, but looking at at Kohler & Glaubrecht it
appears to be Brotia hainanensis.

According to Kohler & Glaubrecht(2001) Brotia is in the
Pachychilidae.  Russ Minton of the Field Museum and I are working on
looking at the relationships of Pachychilus to some of the
pleurocerids and thiariids.  This is indeed an group of freshwater
snails that needs investigation.
