Spiroctenus pallidipes is a species of spider in the family Bemmeridae. It is endemic to the Western Cape province of South Africa.[1]

Distribution

Spiroctenus pallidipes is known only from the type locality at Worcester, at the Touws River Station.[2]

Habitat

The species inhabits the Fynbos Biome and constructs vertical burrows that are enlarged at a depth of 18-23 centimeters into a chamber, with an additional small chamber in the upper wall used as a retreat during danger.[2] The burrows lack a lid or turret.

Description

Both sexes of Spiroctenus pallidipes are known to science.[3] The spider is pale yellowish in color. The carapace with chelicerae is reddish yellow, with the rest being faintly infuscated. The opisthosoma shows a well-defined pattern composed of a series of transverse dark or purplish stripes united by a median longitudinal stripe. The legs are very pale yellowish. The total length is 12.5 millimeters.[3]

Conservation

The species is listed as Data Deficient for taxonomic reasons, as more sampling is needed to collect females and determine the species range.[2]
