Specimen Labels


Polyrhachis hexacantha is restricted to the mountainous parts of southeastern NSW and ACT, and south through the Victorian Alps to Tasmania. It was collected in sympatry with Polyrhachis fuscipes and Polyrhachis smithersi at Smokers Gap in ACT.


Polyrhachis hexacantha is very similar to Polyrhachis fuscipes but differs by the sculpturation of the body consisting of very closely spaced reticulate punctations that gives specimens a rather dull, opaque appearance. In contrast, the sculpturation of the body in P. fuscipes is distinctly finer, notably on the head, and on the mesosomal dorsum it forms more-or-less longitudinal striae with a somewhat semipolished appearance. The intercalary spines in P. hexacantha are rather long, while in P. fuscipes they are distinctly shorter.
