Psammorygma is a genus of African ant spiders found in the deserts of southern Africa, namely the Kalahari desert and the Namib desert.[2] They are somewhat larger spiders, growing up to twenty millimeters in length. The carapace and chelicerae are brightly colored, while the legs and abdomen are generally a darker black or gray. They can be distinguished from other genera by a knob-like proximal extension found on the cheliceral fang and a double row of dorsal spines in a specific location.[2] First described in 1991 by Jocqué, the name is from the Greek psammon, meaning "sand", and orugma, meaning "mine", in reference to the sandy tunnels these spiders live in.[2] As of February 2019, it contains only three species: P. aculeatum, P. caligatum, and P. rutilans.[1]
