The species was sampled from Forest and Savanna biomes.
Both sexes are known. The carapace is orange-brown in color, slightly paler along the midline. The opisthosoma displays mottled pale grey chevron markings.
Austrachelas reavelli is listed as Data Deficient. The species is known from two subpopulations in protected areas (Ngoye Forest and Hluhluwe-uMfolozi Game Park), but is likely under-collected. Additional sampling is required to determine its range and assess threats outside protected areas.
