The eye area has a rust-red underlay and the opisthosoma has a rust-red band in the middle, which can sometimes be very broad and is framed laterally by two or four white spots.strikingly white haired. Opisthosoma posteriorly with 2 round, white spots.

The prosoma of the female is reddish brown, sometimes almost brown-black. The eye area is surrounded by almost white or yellowish hairs, which continue over the pedipalps, which are impressively white or yellowish. The opisthosoma is also surrounded by white-yellowish hairs and sometimes appears quite colourful with a white-yellow stripe in the middle and orange stripes next to it. In some animals, however, the opisthosoma is quite uniformly yellow-brown with washed-out rusty-red spots and dots.
