zebra back spider

Description:

I googled, this creature is most like a zebra back spider, because: - 5 mm in length - Jumping for 1-1.5 inches - black and white stripes But! They all have strips across the body, but this spider has strips along the body. In addition, in all zebra back spiders, all four pairs of legs look the same, but this spider has a slightly thicker and darker pair than the other limbs (you can see it on the first photo). It may seem that these limbs are non-walking legs or claws. At first I thought it was an insect with «horns» (like lucanus cervus), since it seemed to me that he had only three pairs of limbs. Then I saw that he was hanging on his web, and decided that I obviously didn't have enough knowledge in biology. I found in the stock images only one photo of absolutely the same spider, it is also signed as a zebra spider. Explain please, is this some kind of special zebra spider? Maybe the color is different for females and males? On the Internet, only one photo of a spider with this color.

Habitat:
