Distribution
Spiroctenus collinus is known only from the Cape Peninsula, with records from Camps Bay, Kalk Bay, Table Mountain National Park including Signal Hill and Silvermine Nature Reserve, and Tulbagh.[2]
Habitat
The species inhabits the Fynbos Biome and constructs simple burrows with a turret around the entrance.[2]
Description
Both sexes of Spiroctenus collinus are known to science.[3] The carapace is ochraceous with deep olive infuscations in the cephalic region and posterior carapace, and to a lesser extent in lateral radiations from the fovea. The legs are pale ochraceous below, darkened with a brownish tinge above on the femora, and browner from the patellae onwards. The pedipalps are lighter and tinged olivaceous. The opisthosoma is darkened with a brownish tinge above, with testaceous markings posteriorly that bring out central and oblique dark lines. The sides and underside are pale testaceous with a distinct green tinge. The total length is 18 millimeters for females and 12 millimeters for males.[4]
Conservation
The species is listed as Data Deficient, as more sampling is needed to determine its current range.[2] Historic collections from lowland sites may have been lost to urban development, but the species is protected in Table Mountain National Park.
