## Distribution

Ariadna segestrioides is known only from the type locality Dunbrody in the Eastern Cape, at an altitude of 66 m above sea level.[3]

## Habitat and ecology

The species inhabits the Thicket biome and constructs tube signal-webs made in crevices of walls, rocks, fallen tree trunks, or bark of trees.[3]

## Description

See also: Biology:Glossary of spider terms

Females have a blackish-brown carapace, slightly paler in the middle. Chelicerae are reddish-black. Legs are blackish-brown to nearly black, with the two posterior pairs paler distally. Their tarsi and, to a lesser extent, their metatarsi are pale yellowish, while the two anterior pairs of tarsi are reddish.[3]

The abdomen is pallid with a median series of purplish spots above. The underside is faintly suffused with purplish and has a dark purplish patch posteriorly before the spinners. The sternum and labium are blackish-brown. Total length is 10.75 mm.[3]

## Conservation

Ariadna segestrioides is listed as data deficient for taxonomic reasons. More sampling is needed to collect males and determine the species' range.[3]

## Taxonomy

The species was originally described by W. F. Purcell in 1904 from Dunbrody. Only females are known.[3]
