Hogna adjacens


Hogna adjacens is a species of spider in the family Lycosidae. It is endemic to South Africa and is commonly known as the Kimberley burrow-living wolf spider.

Distribution

Hogna adjacens is found in the Northern Cape and Limpopo provinces of South Africa. Notable localities include Kimberley, Vyeboom, and Lekgalameetse Nature Reserve.

Habitat and ecology

This species is a free-living ground dweller that lives in open burrows.
It has been sampled from the Savanna biome at altitudes ranging from 591 to 1218 m.

Description

Hogna adjacens is described only from females.
The cephalothorax is brown without protruding stripes or rays and lacks side bands. It has a very narrow, tightly parallel-edged, rusty yellow median band between the eyes of the black eye field at its narrowest point. The surface of the cephalothorax is uniformly grey-white hairy in the remainder.
The abdomen is dorsally grey-brown with fine and dense yellowish speckles, bearing a slightly blackish median lancet band in front that is bordered on both sides by a pair of blackish spots at its middle and rear end. The sternum is uniformly black, with brown coxae each bearing a lighter basal spot. Other leg segments are uniformly rust-brown and not spotted. The chelicerae are black and grey hairy frontally.

Conservation

The species is protected in Lekgalameetse Nature Reserve. Additional sampling is needed to collect males and determine the full geographic range.

Taxonomy

The species was described by Roewer in 1959, with the holotype locality given as Kalahari. The paratype was collected in Kimberley, with both collections made prior to 1959.
