Arkys alatus, commonly known as the Winged Arkys, is a small ambush hunter, found hiding on foliage, in a variety of habitats along the east coast, stretching from central Queensland to Victoria (there has been some observations in the Far North Queensland).

The name alataus is said to mean having wings or winged.

It is a striking looking spider, with a flattish appearance, ornate patterns and knobs, with overall colours of white, cream, dark-grey or brown overall colour. The cephalothorax (the fused head and thorax of a spider) is just slightly longer than wide. The lateral eyes of the Arkys alatus are on a projecting knob. The pattern on the abdomen has been described as resembling a ghoulish skull or a spectral dog’s head.

One of the identifying features of Arkys alatus is the front half of the abdomen is wide, quickly narrowing about half way back, like a parallel sided tail with projecting horns or hardened tubercles. The abdomen looks like a pair of outstretched wings with two small pairs of horns on the extremities and another two pairs on the trailing edge.

As an ambush hunter, Arkys alatus waits with arms folded for prey to come within range. Its prey are mostly insects, including ants. The eggsac of Arkys alatus is pale in coloured to white (the inner space of the egg sac case is filled with flocculent silk) which is suspended by a stalk underneath a leaf.
