Members of the genus are free-running ground dwellers.Description
Pterartoria species have a total length of 5.0–9.0 mm.The cephalic region is usually raised. The carapace has a longitudinal pale median band on darker brown background and paler submarginal bands. It is clothed in translucent white, adpressed, plumose setae, often with erect black setae in the head region. Eyes in the anterior row are slightly or strongly procurved but more or less straight in some species. The eye region is either totally blackened or has black rings surrounding each eye.
Chelicerae are normally brown, with a longitudinal black stripe in some species. Most are clothed in long, erect black setae. The sternum is scutiform, brown or grey, with central paler band in some species and either marginal band or complete covering of erect black setae.
The abdomen has dark brown or grey background with more or less broad yellow or orange central longitudinal band. Within the anterior portion of the band there is a paler lanceolate area sometimes outlined in black. In some species the posterior half of the band has 3–4 narrow, transverse black stripes. The surface is covered in translucent white, adpressed, plumose setae and often with longer, erect black setae. The ventral surface is pale.
Tibia I has 2 or exceptionally 3 pairs of principal spines ventrally. The metatarsus has 2 pairs of principal spines and smaller distal spines. Spines are normally long, thin and tapering. Legs are clothed in translucent white, adpressed, plumose setae as well as longer erect setae. They are normally pale yellow or orange with grey rings and/or blotches on at least femora but in some species extending to all segments other than tarsi. Tarsi are pale.
