Land yabbies, engaeus or geocherax ?


These crayfish were found by Rob McCormack of Crayhaven on the New South Wales coast. I recently met Daryl Aberhart at his home near Newcastle and he kept a few for me to see. I was surprised at what I saw. I didn't have any reference material with me and although it was simular to engaeus, I'm of the opinion it is Geocherax geocherax, my reasoning is the habitat and burrows are simular to the Victorian Geocherax gracilis/falcata it trunk section is smaller than the tail (abdomen) and their is no hair on the body or claws.
