Perenethis symmetrica is a spider species in the family Pisauridae.[2] The species is commonly known as the Namibia Perenethis nursery-web spider.[3]
Distribution
Perenethis symmetrica has been recorded from Senegal, Djibouti, Democratic Republic of the Congo, Kenya, Tanzania, Namibia, and South Africa.[3]
In South Africa, the species has been sampled from four provinces: KwaZulu-Natal, Limpopo, Mpumalanga, and Western Cape.[3]
Habitat and ecology
The species constructs sheet-webs in vegetation.[3]
It has been sampled from the Fynbos and Savanna biomes at altitudes ranging from 91 to 615 m. The species has also been sampled from maize.[3]
Description
Conservation
Perenethis symmetrica is listed as Least Concern due to its wide geographical range. The species is protected in Kruger National Park. There are no significant threats to the species.[3]
Taxonomy
The species was originally described by R. F. Lawrence in 1927 as Tetragonophthalma symmetrica from Namibia.[1] It was revised by Sierwald in 1997[4] and is known from both sexes.[3]
