Diagnosis
ReferenceDiagnosis
Y. Ke et al. 2024A species of Nanhsiungchelyidae with the following characters: the nuchal is large and crescentic; the nuchal emargination is ‘U’-shaped and deep; a pair of distinct anterolateral processes is absent; the first peripheral is nearly fan-shaped with a rounded free edge; the first vertebral scute is roughly square and slightly wider than long, with roughly parallel and convex lateral edges; and the fourth and fifth vertebral scutes contact at a point. It differs from Basilemys spp., Hanbogdemys orientalis, Jiangxichelys spp., Kharakhutulia kalandadzei, Yuchelys nanyangensis, and Zangerlia spp., which have a shallow nuchal emargination, elongated (narrower) neurals, elongated second to fourth vertebrals, and a trapezoidal nuchal; from Anomalochelys angulata, in which the nuchal is slender and forms the anterolateral processes, the lateral edges of the first vertebral converge anteriorly, the second and third vertebrals are square, the fourth and fifth vertebral scutes form a broad contact, and there is a directional sculpture on carapace; and from Nanhsiungchelys spp., in which the anterolateral processes are prominent, the
nuchal is smaller and trapezoidal, and the first vertebral scute is narrow anteriorly.
