Distribution
Spiroctenus inermis has been recorded from Clanwilliam Pakhuisberg in the Western Cape, and Nieuwoudtville and Oorlogskloof Nature Reserve in the Northern Cape.[2]
Habitat
The species inhabits the Fynbos and Succulent Karoo biomes as a ground-dwelling burrow constructor.[2]
Description
Only males of Spiroctenus inermis are known to science.[3] The carapace is pale ochraceous with the cephalic region darkened with a brownish tinge and a longitudinal ochraceous stripe extending from each side of the ocular area. The chelicerae are pale ochraceous with infuscate lines. The legs are pale ochraceous with femora weakly darkened with brownish lines above. The sternum and underside of coxae are pale yellowish. The opisthosoma is pale yellowish with the upper surface and usually the posterior part of the sides strongly blackened, showing numerous pale yellowish dots and spots but lacking well-defined obliquely transverse dark stripes. The total length is 12-14 millimeters.[3]
Conservation
The species is listed as Data Deficient for taxonomic reasons, as females remain unknown and the full species range requires further study.[2]
