Eusparassus

They are medium to large huntsman spiders, their bodies measuring from 10mm to 30mm. Their eyes are arranged in two rows, the anterior one being slightly procurved, while the posterior ones are relatively straight. They are pale gray to dark brown spiders, with a uniform coloration in their body. Or with a clearly patterned body, and banded legs.[5]

They can be identified by the presence of two pairs of tibial spines on the legs. And from the Olios genus by the palpal bulb morphology.[3]

They are commonly found in arid and semiarid deserts of Africa and most parts of Eurasia. Where they inhabit stony habitats, and build retreats in crevices. In which they are one of the most common predators. They can be found in very high elevations from 3,000 to 4,000m above sea level.[3]

They make silken papery webs, which are usually found in crevices or the underside of flat stones. This webs are used as protection during molts, or as a retreat during the day. Though females of this species lay their egg sacs insides this retreats.[3]
