Diores radulifer is a species of spider in the family Zodariidae.[2] It occurs in southern Africa and is commonly known as the Steinkopf Igloo spider.[3]
Distribution
Diores radulifer is found in South Africa and Namibia.[2] In South Africa, it is known from the Northern Cape province, including Steinkopf where it was originally described.[3]
Habitat
The species inhabits the Desert and Succulent Karoo biomes at altitudes ranging from 250 to 1169 metres above sea level.[3]
Description
Males of Diores radulifer have a total length of 4.08 mm, while females range from 4 to 7 mm. The carapace, chelicerae, and legs are brownish-yellow, with the sternum being pale yellow.[4]
Males have a pale dorsal scutum flanked by narrow dark lateral stripes, with the remainder of the opisthosoma being yellow. Females have a yellowish-orange carapace and chelicerae, yellow legs and sternum, and the abdomen dorsally shows two large black longitudinal bands with sinuous margins.[4]
Ecology
Diores radulifer are free-living ground-dwellers that construct igloo-shaped retreats with small stones, characteristic behavior of the genus Diores.[3]
Conservation
The species is listed as Least Concern. Despite having a restricted distribution in South Africa, extensive areas of natural habitat remain within its range and it faces no threats. It is protected in Richtersveld National Park and Namaqua National Park.[3]
