Tyrotama is a small to medium (4.8-9.5mm body length) rupicolus genus endemic to South Africa, Namibia and Angola. This genus was until recently known as Tama. They occur in rocky or mountainous areas under stone on rock. They attach themselves under the stone where they construct a circular “kraal” retreat with silk trip lines radiating from it. This “kraal and its egg sac is constructed from silk with embedded sand particles. The prey is caught in the same fashion as the genus Hersilia but is taken to the retreat to be consumed.
