The species inhabits the Savannabiome. It lives in silk-lined burrows closed with a trapdoor.
Description
Idiops grandis is known only from females. The upper surfaces of appendages and carapace are castaneous, with the legs having a reddish tinge. Ventral surfaces are paler with the sternum and coxae of the last two pairs of legs being yellowish brown. The coxa is clothed inferiorly with stout bristles, not spinules.
The species was originally described by John Hewitt in 1915 as Acanthodon grandis from Umfolozi. The species has not been revised and requires taxonomic work, as it has three pairs of sigilla and may need to be moved to Segregara.
