Distribution

Diores triarmatus is found in Botswana, Democratic Republic of the Congo, Tanzania, Uganda, South Africa, and Zambia. [2] In South Africa, it has been recorded from three provinces: Gauteng, Limpopo, and Mpumalanga. [3]

Males of Diores triarmatus have a total length of 4.87 mm, while females are larger at 5.62 mm. The carapace, chelicerae, and legs are yellowish-orange, with the sternum being yellow. Males have a dark sepia scutum on the opisthosoma. Females have similar carapace coloration but lack the scutum, instead having a pale dorsal pattern on a dark background. The sides are sepia with an oblique pale patch, and the venter is pale. [4]

Ecology

Diores triarmatus are free-living ground-dwellers that construct igloo-shaped retreats with small stones, characteristic behavior of the genus Diores . [3]
