Taxonomic Comments
Genetic examination of molecular phylogeny of global Planorboidea at the COI and 18S molecular markers indicates all North American taxa within the subfamily Planorbinae form a well-supported clade, as yet unnamed but termed C-Clade (Albrecht et al., 2007).

Range Extent>2,500,000 square km (greater than 1,000,000 square miles)
Number of Occurrences81 to >300
Rank Reasons
This species ranges widely in Vermont west to North Dakota, south to Ohio and Illinois, northward to Great Slave Lake. Overall the species is stable and threats are minimal to nonexistent; although it can be uncommon in parts of its range (i.e. Indiana).
Range Extent Comments
This species ranges in Vermont west to North Dakota, south to Ohio and Illinois, n orthward to Great Slave Lake (Burch, 1989).
Occurrences Comments
It is common in New York (Jokinen, 1992). In Pennsylvania, it occurs in the Delaware and Ohio basins (Evans and Ray, 2010). In Indiana, Pyron et al. (2008) found it at only one site (Lake Wawasee) of 123 surveyed but it has been documented historically in Indiana Sand Dunes National Seashore.
Ecology & Habitat

Habitat

Habitat includes lakes and ponds and quiet portions of streams. In Indiana it was found in sand and riprap substrate and submerged macrophytes and is most limited to the lakes area of Indiana (Pyron et al., 2008).
