Species

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]

Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found in all tropical and subtropical regions of South America, Africa, Madagascar, Australia-New Guinea, New Zealand, Arabia and the Indian subcontinent. Most species are daytime hunters and live together with ants, mimicking their behavior and sometimes even their chemical traits. Although little is known about most zodariids, members of the genus Zodarion apparently feed only on ants; a number of other genera in the family are apparently also ant specialists.

First described in 2020 by Rudy Jocqué and Arnaud Henrard, the spider is small, measuring between 2.24 and 3.26 mm in length. The male is smaller thamn the female. The carapace is brown, bottle-shaped and has a mottled pattern only on the male. The abdomen is grey, oval and also lacks any pattern on either sex. Most of the remainder of the spider is brown. The most characteristic feature of the genus are the long legs, which can measure up to 9.15 mm (0.360 in) long in the case of the back legs of the female. The legs are also yellow. The male also has a distinctive large curved median apophysis and curved retrolateral tibial apophysis on the palpal bulb which helps identify this species against others in the genus.
