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

Distribution

[edit]

Idiops thorelli is known only from South Africa, but no exact locality is recorded for the type specimen.[3]

Habitat and ecology

[edit]

The habitat and lifestyle of the species are unknown.[3]

Description

[edit]
See also: Glossary of spider terms

Idiops thorelli is known only from males. 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.[3]

Conservation

[edit]

Idiops thorelli is listed as Data Deficient for taxonomic reasons. The type material needs to be located for redescription of the species before it can be properly sampled.[3]

Etymology

[edit]

The species is named after Swedish arachnologist Tamerlan Thorell (1830–1901).

Taxonomy

[edit]

The species was described by Octavius Pickard-Cambridge in 1870 with the type locality given only as "South Africa". The species is known only from a single specimen collected prior to 1870. More sampling is needed to collect females and more males to determine the species' range.[3]
