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. Note that the colour of Myrmarachne species seems to vary, at least partly, with the colour of the ants they are running with. The apparent differences among the images shown on this page may also possibly indicate that more than one species is presented.

Spider(s) with a very similar appearance: Myrmarachne species.
