Psammorygma is a genus of African ant spiders found in the deserts of southern Africa, namely the Kalahari Desert and the Namib Desert.[2]
Description
[edit]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]
Etymology
[edit]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]
Species
[edit]As of September 2025[update], the genus contains three species:[1]
- Psammorygma aculeatum (Karsch, 1878) - South Africa
- Psammorygma caligatum Jocqué, 1991 - Namibia
- Psammorygma rutilans (Simon, 1887) - South Africa
