Idiops flaveolus is a species of spider in the family Idiopidae. [2] It is endemic to South Africa and is commonly known as the Grahamstown Idiops trapdoor spider. [3]

Contents

Distribution

Idiops flaveolus is an Eastern Cape endemic recorded from Grahamstown and East London at altitudes ranging from 56 to 565 m above sea level. [3]

Habitat and ecology

The species inhabits the Thicket biome. It lives in silk-lined burrows closed with a trapdoor. [3]

Description

Idiops flaveolus is known from both sexes but has not been illustrated. The carapace and legs are orange-yellow-brown in colour and very sparingly furnished with hairs. The legs have a few fine spines. The abdomen is dark yellow-brown. The form of the cephalothorax is broadly but regularly oval, depressed above with fairly marked normal furrows and indentations. Total length is 19 mm. [3]

Conservation

Idiops flaveolus is listed as Data Deficient due to insufficient knowledge about its location, distribution and threats. More sampling is needed to determine the species' range. [3]

Taxonomy

The species was originally described by Reginald Innes Pocock in 1901 as Acanthodon flaveolum from Grahamstown, with the male described by Hewitt in 1918. The species has not been revised. [3]
