Diagnosis
ReferenceDiagnosis
E. Vlachos 2018Stylemys inusitata can be diagnosed as a member of Stylemys based on the hexagonal neurals II–VII and the shape of the humero-pectoral sulcus. Stylemys inusitata differs from Stylemys nebrascensis in the more prominent epiplastral lip and the short gulars that do not cover the entoplastron and from Stylemys capax in the absence of octagonal neural II and absence of gulars covering of the anterior part of the entoplastron.
