Legs with no constrictions, femora slightly curved; three or four large heel spines gradually increasing in length from proximal to distal, followed by a smaller pair; proboscis narrowing at two thirds length showing a variable degree of rough, scabby cuticle with dark marks at the distal portion in the Victorian and Tasmanian material; chela fingers short with straight cutting edges, in some specimens somewhat irregular, movable finger slightly shorter, fingers similarly pigmented as distal proboscis portion. The specimens proposed in the complex have a molecular divergence&gt;8 % in COI and&gt;3 % ITS sequence distance from other congeneric species for which these DNA fragments are available.
