Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Franz et al. 2020 | Medium to large-sized tortoise, PL est. 345–480 mm, CL est. 450–600 mm for subadult to adult males (based on comparisons with complete shell of C. a. alburyorum from Franz and Franz, 2009; estimates for PL and CL of female C. a. sementis not available). Plastron of Chelonoidis a. sementis differs from that in C. a. keegani and C. a. alburyorum in having epiplastron with gular/ humeral sulcus less distinct, ventral (outer) surface more rugose, and posterior-lateral margin sharper (more dorso-ventrally compressed). Hypoplastron with lateral margin thinner but more rugose, and abdominal/femoral sulcus straighter (than in C. a. keegani only). Xiphiplastron thinner overall for its size, especially at lateral margin; in dorsal or ventral aspect, xiphiplastron much longer than it is wide (nearly square-shaped in the other two subspecies). |
