DistributionNew Guinea (Lakes Murray and Balimo, Fly and Aramia rivers, Western District's savannah regions north of the Fly River)

Type locality: Mawa, Lake Murray, Western District, Papua New Guinea.  
TypesHolotype: AMS 21425 
DiagnosisDiagnosis (subgenus Chelydera): Large riverine turtles; carapace broadly oval with noticeable flaring about marginal scutes 8–10; plastron narrow, covering only about half of the anterior orifice of the shell in ventral view; plastron of moderate length, approximately twice as long as its width measured anterior to the bridge; head and neck longer than carapace; intergular scute rhomboid in shape with width approximately equal to length. Neck dorsum finely reticulated, lacking obvious tubercles. Osteologically, atlas (C1) elongated; cervical vertebrae 2–4 greatly elongated (centrum about three times as long as wide); transverse processes of cervical vertebrae thickened, not bladelike as in subgenera Chelodina and Macrochelodina. Skull dorsoventrally flattened, in some species also laterally expanded, resulting in antero-posterior enlargement of palatines. Hyolaryngeal assemblage highly modified; extreme elongation of corpus hyoideum along sulcus tracheae; anterior cornubranchiale expanded, elongated, extending beyond posterior cornubranchiale; epibranchials fully ossified in adults, cartilaginous throughout life in species of the other subgenera. Anterior bridge struts enlarged; suture with pleural 1 extends half-way across pleural; proximal suture of strut enlarged and also contacts 2nd pleural in very large specimens; posterior bridge strut enlarged and thickened, but does not contact pleurals; ilium sutures with 8th pleural and pygal and is latero-posteriorly rotated. Exposed neural bones usually absent (except for Chelodina burrungandjii, typically with 3–6 exposed neurals; Smales 2019). Fluid from ducts in the inguinal and axillary pockets with noticeable odour, but not pungent (Shea et al. 2020: 430). 
CommentHabitat: freshwater (rivers, swamps)

Type Species: Chelodina parkeri Rhodin & Mittermeier 1976 is the type species of the subgenus Chelydera Thomson and Georges in Shea et al. 2020. 
EtymologyNamed after Fred Parker, Indian-born Australian herpetologist.

The name Chelydera is a combination of the Greek χέλυς/χέλυδρος (chelys/chelydros), meaning both a turtle (cf. the similarly snake-necked turtle genus Chelus Duméril 1806) and a water snake, and δειρή (deire), the neck (f.) (Liddell & Scott 1897; Brown 1956). This is in reference to the common name for this group, the snake-necked turtles. Shea et al. 2020 use a feminine name for the subgenus to agree with Chelodina, to avoid a change in gender of any adjectival specific epithets if Chelydera is treated as generically distinct by some authors.
