Olios sp. [image N. Larsen ]

About 251 species worldwide, of which 27 are recorded from southern Africa. Olios is a group of smaller spiders (Body length is 10-14 mm) within the Sparassidae that in general are either light brown and live under rocks (rupicolus) or green and live on trees (arboreal). The rock-dwelling species produce a flattish sac retreat and egg sac attached to the underside of a rock or stone. These spiders share a similar habitat to the flatties (Selenopidae).

Taxonomy

This genus has been used as a dumping ground for various species and in time many of these will probably be placed in other genera. For instance, the rupicolus species may in time be removed from Olios and placed in the genus Eusparassus. Olios it appears will be retained for the green arboreal species.
