Etymology
editThe species is named after Lake Kariba, near where the type specimens were collected.
Distribution
editR. kariba is found in Botswana, Zimbabwe, and South Africa. The species was originally described from Zimbabwe by Norman I. Platnick and E. Griffin in 1990. In South Africa, it has been sampled from several localities in Limpopo province, at elevations from 238 to 1,528 meters above sea level.[3]
Habitat and ecology
editThis very small free-living ground spider is adapted to life in sandy habitats. Like other Rastellus species, it uses its rastelliform digging apparatus to excavate burrows. Specimens are frequently captured in pitfall traps, indicating active movement across the sand surface. The species likely spends much of its time buried beneath the sand.[3]
