Theridion purcelli is a species of spider in the family Theridiidae.[1] It is found in Saint Helena, Namibia, and South Africa, and is commonly known as Purcell's Theridion comb-feet spider.[2]

Distribution

Theridion purcelli is found in Saint Helena, Namibia, and South Africa.[1] In South Africa it is known from all provinces.[2]

Habitat and ecology

This species builds a conical retreat of twigs and leaves in its three-dimensional labyrinth web.[2]

It has been sampled from all the floral biomes except the Indian Ocean Coastal Belt Forest and Succulent Karoo biomes at altitudes ranging from 5 to 1809 m. The species is also commonly found in crops including citrus, cotton, macadamia, maize, strawberries, sunflowers and tomatoes. It is also synantropic and found in and around houses.[2]

Description

The abdomen is subglobular and furnished with bristly setae. The colour is dull yellowish with a longitudinal central sharply dentated band, obtuse anteriorly and tapering towards the spinnerets. The band is marked with pale spots. Ventrally the abdomen is black-brown with a central white patch. The female resembles the male.[3]

Conservation

Theridion purcelli is listed as Least Concern by the South African National Biodiversity Institute due to its large geographical range. The species is protected in six reserves.[2]

Etymology

The species is named after William Frederick Purcell, a South African naturalist and museum curator who made significant contributions to the study of southern African arachnids.

Taxonomy

Theridion purcelli was described by Octavius Pickard-Cambridge in 1904 from Salt River in the Western Cape. The species has not been revised and is known from both sexes.[2]
