Helicostoa is also the only genus in the family Helicostoidae.[4] According to taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Helicostoidae has no subfamilies.
Helicostoa sinensis was previously tentatively placed within the superfamily Rissooidea.[3] and before that it was in the superfamily Vermetoidea.[3]
Helicostoa sinensis is only found in China,[4] more specifically in the Yangtze River.[3]
This freshwater snail lives attached or bonded to blocks of limestone.[4]
