DistributionCanada (S Ontario, Quebec),
USA (along the Atlantic Coastal Plain in Maine, SE New Hampshire, Massachusetts, Connecticut, S New York, Pennsylvania, New Jersey, Delaware, Maryland, Virginia, West Virginia, North Carolina, South Carolina, Georgia, N Florida, Ohio, Indiana, Michigan, NE Illinois)

Type locality: vicinity of Philadelphia, Pennsylvania (designated by MITTLEMAN 1945)  
Reproductionoviparous. Exhibits temperature‐dependent sex determination (TSD) fide Cornejo-Páramo et al. 2020 (and references therein). 
TypesType: BMNH 1853.11.30.25 (possibly the type of Geoclemmys sebae fide P. Campbell, pers. comm., March 2019). 
CommentType species: Clemmys guttata is the type species of the genus Clemmys RITGEN, 1828. HOLMAN & FRITZ 2001 and FELDMAN & PARHAM 2002 suggested to treat Clemmys as a monotypic genus with C. guttata as its sole member. However, both author teams suggested different names for the other members of Clemmys (marmorata, muhlenbergii, insculpta).

Illustrations: Picture in Draco 13 (4): 96 (2003).

Habitat: freshwater (swamps, ponds, rivers) 
EtymologyClemmys = tortoise.
Named after Latin “guttata” for spotted, referring to the scattered yellow spots on the carapace.
