Its body length is described as about 8-12 mm and 4-5 mm for females and males respectively.[1][2] X. elegans is described as showing strong sexual dimorphism in size; Males in this species tend to be less than half the size of females.[1] X. elegans has a brown cephalothorax that has a lighter area, sometimes this lighter area is outlined in white.[2] It has a light tan band through the eye region and an abdomen that has brown spots outlined in white.
