Tyrotama abyssus is a species of spider in the family Hersiliidae.[2] It is a southern African endemic and is commonly known as the Swartberg Two-tailed Ground Spider.[3]
Distribution
Tyrotama abyssus occurs in Lesotho and South Africa.[2] In South Africa, the species is presently known from two provinces at altitudes ranging from 172 to 1,706 m above sea level.[3]
Habitat
The species is found in Nama Karoo and Succulent Karoo biomes. It constructs circular webs under stones, with the web attached to the underside of the stone and hanging like a veil.
