DistributionUSA (Alabama, Arizona, Arkansas, Illinois, Tennessee, Louisiana, Mississippi, Missouri, Oklahoma, Texas)

introduced to Florida (Krysko et al. 2011)

Type locality: vicinity of New Orleans, Louisiana (restricted by K.P. SCHMIDT 1953).  
ReproductionOviparous. Temperature‐dependent sex determination (TSD) fide Nemesházi & Bókony 2023. 
TypesSyntype: USNM 21 
CommentTaxonomy: STARKEY et al. (2003) suggested to elevate C. p. dorsalis to full species status. These authors also questioned the validity of the other subspecies. Because morphological intermediate specimens are known between C. dorsalis and C. p. picta, C. p. marginata, and C. p. bellii (Ernst, 1967, 1970, and others), the taxonomy of dorsalis is debatable (Reynolds et al. 2007, TTWG 2012).

Habitat: freshwater (lakes, rivers) 
EtymologyNamed after the prominent middorsal stripe on the carapace (the “dorsum”).
