Myrmarachne species (QM)|
(apparently an undescribed South Queensland species)
female: 7 mm|
male: 9 mm
Any surface where ants can be found, the spiders tending to run with ants along established ant pathways
A bite by this species may cause local inflammation
The distinguishing feature of this species is the partial constriction of the cephalothorax and/or the
abdomen into two segments to produce an ant-like body shape. The very large porrect (forward pointing)
chelicerae on the male are another striking feature. The female's palps are long and thin with paddle-shaped
ends. At least on some Myrmarachne species the cephalothorax appears to have a helmet-like shape.
It should also be pointed out that the
taxonomy of the Australian Myrmarachne genus is currently being revised, the most recent example of this being the following paper: Pekar S., Petrakiva L.,
Corcobado G., and Whyte R. (2017) "Revision of eastern Australian ant-mimicking spiders of the genus Myrmarachne (Araneae, Salticidae) reveals a complex
of species and forms" Zoological Journal of the Linnean Society, 197(3), 642-676.
Spider(s) with a very similar appearance: Many other Myrmarachne species.
