The Arkys, a group of spiders known as Triangular Spiders or Ambush Spiders is a genus of Australian araneomorph spiders in the family Arkyidae. The Araneomorphae are an infraorder of spiders, that are distinguishable by chelicerae (the mouthparts of the subphylum Chelicerata) that point diagonally forward and cross in a pinching action.
Arkys are usually small, with a triangular shaped abdomen, found in Australia and some of its surrounding islands. This group of spiders do not build webs, instead they can often be found on leaves and tips of flower heads.
