Chelonides wittei
(From Anquetin et al. 2017:330): Chelonides wittei is based on a series of specimens, in particular a partial shell (GZG 773-1), a partial skull (GZG 773-2), and several isolated shell and girdle elements. The full type series is illustrated in Maack (1869, pl. 33.118) and referenced in Karl et al. (2007). The partial shell GZG 773-1 was designated as Hauptvertreter (main representative) of the species by Maack (1869). This led Karl et al. (2007) to refer to this specimen as the holotype, but this designation is incorrect with regard to current rules of zoological nomenclature (ICZN 1999, art. 74). We here formally designate GZG 773-1 as the lectotype of Chelonides wittei. As a result, this specimen now serves as the sole bearer of the name, regardless of the nomenclatural interpretation being applied.

J. Anquetin et al. 2017 | Chelonides wittei differs from all other “eurysternids” in small size and in the presence of moderate keel on the posterior neurals, small costo-peripheral fontanelles, thoracic ribs that are partly apparent on the dorsal surface of the distal portions of the costal bones, wide vertebral scutes, a large and oval central plastral fontanelle, and elongated and narrow lateral plastral fontanelles. |
