Valvata sincera Say, 1824

New York State Distribution [-]
Apparently confined to the St. Lawrence/Champlain watershed in northern New York as well as the larger lakes in central New York and the depths of Lake Ontario.

Global Distribution [-]
This is a northern species found from the Arctic Circle southward to Connecticut and Minnesota. It seems seems to have been extirpated from states further to the south (e.g., Indiana, Pennsylvania).
