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
recurved, while the posterior ones are relatively straight. They are pale gray to dark brown spiders, with a uniform coloration in their body. Some may have a clearly patterned body with banded legs.[5]
Identification

tibial spines on the legs and distinguished from the Olios genus by the
palpal bulb morphology.[3]
Habitat
They are commonly found in
arid and
semiariddeserts of
Africa and most parts of
Eurasia where they inhabit stony habitats and build retreats in crevices. They are one of the most visible arachnid predators in their habitats. They can be found in very high elevations from 3,000 to 4,000m
above sea level.[3]
Webs
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. Females of this species lay their
egg sacs inside the retreats.[3]
