Chersina langebaanwegi
Derivation of name: The species name, meaning of Langebaanweg, derives from the site where it was collected, and is currently the only site at which it has been identified. Worth noting is that turtles represent the most common vertebrate taxon at Langebaanweg, and that this species is by far the most common taxon in the turtle assemblage. This species is dedicated to Prof. Margaretha D. Hofmeyr (19502020) for her commitment to the study of African extant tortoises and for having promoted the study of the fossil tortoises from Langebaanweg.

| M. Delfino et al. 2024 | Member of testudinid genus Chersina because of the following combination of characters: wide vertebral scutes almost equal to the vertebral scutes; single trapezoidal suprapygal, notched pygal, and distinct gular protrusion covered by fused gulars scutes. Differing from Chersina angulata regarding the following characters: the shell is distinctly domed and not relatively low and elongated as in C. angulata, the nuchal is not as significantly arched (in anterior view) as that of C. angulata, and does not develop a ventral transversal ridge with medial notch and a dorsal shelf as in C. angulata, the cervical is, on the dorsal surface, much broader and proportionally longer than that of C. angulata, the first neural is hexagonal and not rectangular as in C. angulata, most of the neurals host the ribheads and not regularly the costals as in C. angulata, the sixth marginal scute does not contact the third pleural scute as in C. angulata, the anterior protrusion of the plastron (the gular protrusion of the epiplastra) is comparatively more developed than in C. angulata (especially in males, the dorsal surface of the epiplastral lips is nearly flat or very slightly convex and not variably concave as in C. angulata, the epiplastral lips in most of the cases end posteriorly with a nearly straight or moderately convex profile (in most cases not producing any significant pocket) and not with a very strong convexity as in C. angulata (which regularly has a very deep gular pocket), the entoplastron is wider than long instead of being longer than wide, or circular, as in C. angulata. |
