Gopherus berlandieri

Texas Tortoise, (Berlandier's Tortoise)

Texas-Gopherschildkröte

Texas-goferskildpadde

1857 Xerobates berlandieri Agassiz
Testudo berlandieri Strauch 1862
Xerobates gopher berlandieri Gray 1873
Gopherus berlandieri Stejneger 1893
Gopherus polyphemus berlandieri Mertens & Wermuth 1955
Scaptochelys berlandieri Bramble 1982

Remarks: This species was reported to occur in San Luis Potosi by Taylor (1949), but without localities or vouchers. The record was repeated by many others (e.g., Auffenberg & Franz 1978; Fritz & Havas 2006; McCord & Joseph-Ouni 2004c). However, the most recent checklists for San Luis Potosi (Lemos-Espinal & Dixon 2013; Lemos-Espinal, Smith & Woolrich-Pińa 2018) did not include the species. It is tentatively included for the state herein on the basis of Rhodin, Iverson, Bour, Fritz, Georges, Shaffer & Dijk (2017), who plotted two localities that are clearly within the state.
Introduced to: Mexico (Jalisco), USA (California).
Distribution: Mexico (Coahuila, Nuevo Leon, San Luis Potosi, Tamaulipas, Veracruz), USA (Texas).


Gopherus evgoodei

Sinaloan Desert Tortoise, Sinaloan Thornscrub Tortoise, (Goode's Thornscrub Tortoise)

Sinaloa-Gopherschildkröte

Sinaloa-goferskildpadde

2016 Gopherus evgoodei Edwards, Karl, Vaughn, Rosen, Meléndez-Torres & Murphy

Remarks: Previously regarded as the southernmost populations of agassizi or, more recently, of morafkai.
Distribution: Mexico (Chihuahua, Sinaloa, Sonora).


Gopherus flavomarginatus

Bolson Tortoise, Mexican Giant Tortoise, Mexican Giant Gopher Tortoise

Bolson-Gopherschildkröte, Mexikanische Gopherschildkröte

Bolson-goferskildpadde

1959 Gopherus flavomarginatus Legler
Gopherus polyphemus flavomarginatus Wermuth & Mertens 1961

Distribution: Mexico (Chihuahua, Coahuila, Durango).


Gopherus morafkai

Sonoran Desert Tortoise, (Morafka's Desert Tortoise)

Sonora-Gopherschildkröte

Sonora-goferskildpadde

2011 Gopherus morafkai Murphy, Berry, Edwards, Leviton, Lathrop & Riedle

Remarks: This species, along with evgoodei, represents what was formerly considered the southern populations of agassizii. Previously included the populations now assigned to evgoodei. Rhodin, Iverson, Bour, Fritz, Georges, Shaffer & Dijk (2017) erroneously included Sinaloa in the distribution, however, records of morafkai from this state refer to evgoodei, which also corresponds to these authors' range maps. Several individuals have been reported from southwesternmost New Mexico, although there is no indication that the species has become established in the state (Bartlett & Bartlett 2013, as G. agassizii).
Distribution: Mexico (Sonora), USA (Arizona).
