Assessment Rationale:

Araneus hortensis has not been found since its original description in 1859 (Blackwall 1859). Nothing is known about its current population, habitat requirements, or threats. Taxonomic clarification is needed for this species. If it is a valid species, basic information would then be needed on its distribution, ecology and possible threats to be able to assess its status. Therefore it is currently assessed as Data Deficient.

Geographic Range:

The only reference for this species is from an unspecified locality on the Island of Madeira, Portugal (Blackwall 1859).
