ID Keys

Key to subgenera and species from Georges & Thomson 2010

1. Plastron broad, covering or almost covering the anterior orifice of the shell in ventral view; intergular scute approximately twice as long as the suture between the pectoral scutes; length of head and neck equal or slightly less than length of the carapace; dorsum of neck with many blunt conical tubercules; fluid with a pungent odour secreted from ducts in the inguinal and axillary pockets when distressed -......................................................................................................................................................................subgenus Chelodina.............................2
-.
