Distribution

Anyphops immaculatus occurs in five South African provinces: Free State, Gauteng, Eastern Cape, KwaZulu-Natal, and Western Cape. Notable localities include Florida, Pretoria, Bloemfontein, East London, and Cathedral Peak. [3]

Habitat and ecology

The species inhabits Fynbos, Grassland, and Thicket biomes at altitudes ranging from 52 to 1693 m above sea level. [3] These are free-living cryptozoic nocturnal ground living spiders that are sometimes found in houses. [3]

Description

Known only from the male. The carapace is yellow-brown with thoracic striae and some very faint radiations from it a little darker, and eyes surrounded by a blackened area. The chelicerae are yellow brown. [3]

The opisthosoma is yellow with a few blackish brown spots. The legs are without markings except for two very faint brown bands on the anterior tibiae. The anterior tibiae have 5 pairs of inferior spines. [3]

Total length is 8.5 mm. [3]

Conservation

Anyphops immaculatus is listed as Least Concern due to its wide geographical range. The species is protected in the Swartberg Nature Reserve and Amanzi Private Game Reserve. [3]

Taxonomy

The species was originally described by Lawrence in 1940 as Selenops immaculatus from Florida in Gauteng. [1] It was later transferred to the genus Anyphops by Benoit in 1968. [3]
