Diagnosis
ReferenceDiagnosis
E. Vlachos 2018Echmatemys naomi can be diagnosed as a member of Echmatemys based on the characters listed for that clade above. Echmatemys naomi differs from other Echmatemys based on the following combination of characters: contact between marginal II and vertebral I, neural I much longer than wide, vertebral IV/V sulcus placed on the last neural, clear contact of large axillary scute with marginal IV and V, wide suprapygal V, and large inguinal scute that does not contact the femoral scute in ventral view.
