Its underside

This species, though very small, is relatively easy to recognise because of of the unusual shape of its cephalothorax and because its abdomen is partly divided into two sections, giving this spider the appearance of an ant. The spider presumably uses this disguise to ambush ants and other insects. Another distinctive anatomical feature of this species is the fact that the first pair of legs are much stouter than the other legs and have a stiff brush of hairs on the underside of the tibia.

Spider(s) with a very similar appearance: While the appearance of this spider is distinctive, several other similar and closely related genera exist, including Rhombonotus gracilis and Myrmarachne species. Note that some of the images above could actually be of a Rhombonotus species, those species that are now listed as belonging to the Rhombonotus genus originally being known as Ligonipes species.
