Diagnosis
ReferenceDiagnosis
D. G. Broadley 1997A species of Psammobates apparently closest to P. oculiferus, but different in the more depressed carapace, with a step slop anteriorly, the wider anterior peripherals and the very broad posterior lobe of the plastron. The anterior neural formula is ? ? <6 <6 4.
G. L. Georgalis et al. 2021Psammobates antiquorum can be diagnosed as a member of Testudinidae, Geochelona, and Psammobates by the full list of shell characters provided for these clades above. Psammobates antiquorum can be differentiated from other species of Psammobates by its more depressed carapace, wider anterior peripherals, and its rather broad posterior lobe of the plastron.
