Austrachelas is a genus of spiders in the family Gallieniellidae. The genus contains ten species, all endemic to South Africa. [1]

Contents

Taxonomy

The genus was transferred from the Corinnidae to the Gallieniellidae by Haddad et al. in 2009. [2] The genus was revised by Haddad et al. (2009) and supplemented by Haddad & Mbo (2017). [3]

Distribution

All species are endemic to South Africa, distributed across the provinces of Eastern Cape, KwaZulu-Natal, Limpopo, Mpumalanga, and Northern Cape. [4]

Description

Austrachelas are medium to large-sized spiders with body length ranging from 4.7–15.3 mm. The carapace is orange-brown to bright wine-red in colour, paler along the midline, and raised evenly along the midline, sloping sharply posteriorly. The eyes are arranged in a closely situated group with the anterior eye row procurved and posterior eye row straight or very slightly recurved. Chelicerae do not protrude far beyond the anterior margin of the carapace. The opisthosoma is elongate and grey dorsally with cream chevron markings, pale laterally and ventrally. Males possess a short dorsal scutum that is absent in females. The legs have densely scopulate anterior metatarsi and tarsi with strongly spined posterior legs. [4]

Ecology

Austrachelas species are free-running ground dwellers typically sampled through visual search, pitfall traps, and litter sifting. They inhabit various biomes including Forest, Grassland, Savanna, and Indian Ocean Coastal Belt. [4]

Species

As of September 2025, the genus contains ten species: [1]
