It was recombined as Gopherus brevisterna by Bramble (1982); it was recombined as Gopherus brevisternus by Reynoso and Montellano-Ballesteros (2004), Vlachos (2018).

Diagnosis
ReferenceDiagnosis
E. Vlachos 2018Gopherus brevisternus can be diagnosed as a member of Gopherus based on the characters mentioned above. Gopherus brevisternus differs from other, early to middle Miocene Gopherus in the less differentiated neural series with an hexagonal neural IV and vertebrals that are much narrower than the pleurals. Gopherus brevisternus further differs from Gopherus mohavensis in the narrower cervical scute.
