W. G. Joyce and J. Anquetin 2019Compsemys russelli can be diagnosed as a paracryptodire and a representative of Compsemys by the full list of shell characters listed for those clades above. Compsemys russelli can most easily be differentiated from Compsemys victa by possessing two suprapygals that lack lateral contact with peripheral X
