Type species: Chelodina oblonga J. Gray, 1841 , by original designation (but sensu their invalidly designated neotype – see Kuchling, 2010 for discussion).

Revised Diagnosis: Carapace broadly oblong, flattened dorsally and furrowed along midline; deep reticulated ornamentation of shell often present. Carapace elongated anteriorly and shortened posteriorly giving a narrow carapace with negligible posterior flaring; generalised reduction of carapace margins anteriorly and posteriorly; 5–8 ( Smales 2019) exposed coffin-shaped neurals present. Anterior bridge strut small, sharply angled posteriorly with minimal suture surface with pleural 1; posterior bridge strut small, does not contact pleurals. Plastron long, narrow, more than twice as long as width measured immediately anterior to bridge, covering only about half of anterior orifice of shell in ventral view. Ilium in contact with posterior half of 8th pleural and pygal. Head and neck length, when fully extended, longer than carapace length; dorsum of neck finely reticulated, lacking obvious tubercles. Atlas (C1) moderately elongated; cervical vertebrae 2–4 greatly elongated (centrum about three times as long as wide). Transverse processes of cervical vertebrae thin and bladelike. Hyolaryngeal assemblage highly modified; elongation of corpus hyoideum along sulcus tracheae; anterior cornubranchiale expanded but not flattened throughout length, elongated, but not extending beyond posterior cornubranchiale; epibranchials cartilaginous throughout life.
