Emys lativertebralis was named by Cope (1877). Its type specimen is USNM 2576 (holotype), a partial shell (shell fragments constituting an almost complete shell), and it is a 3D body fossil. Its type locality is Gallinas River region, which is in a Wasatchian terrestrial horizon in New Mexico.

It was recombined as Echmatemys lativertebralis by Hay (1906) and Vlachos (2018).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
E. D. Cope 1882 (Emys shaugnessiana)the bones of this species are very thick
E. Vlachos 2018Echmatemys lativertebralis can be diagnosed as a member of Echmatemys based on the full list of characters provided above for that clade. Echmatemys lativertebralis differs from other Echmatemys based on the following combination of characters: covering of the lateral parts of the nuchal by pleural I, contact between vertebral I and marginal II, longer than wide suprapygal I, humero-pectoral sulcus located posterior to the entoplastron, and well-developed axillary and inguinal buttresses.
