See also: Glossary of spider terms

Idiops crudeni is known from both sexes but has not been illustrated. The carapace and appendages are yellowish with brown or olive tinge, with lower surfaces a little paler. The abdomen is pale above and below with a faint purplish tinge on the median area anteriorly above. Total length is 21.5 mm.[3]

Conservation

[edit]

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

Taxonomy

[edit]

The species was originally described by John Hewitt in 1914 as Acanthodon crudeni. The placement of the species is problematic and taxonomic revision is needed.[3]
