Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | RE: Last seen at its single GB location, in the Chilterns, 1938. This area has undergone major habitat change and been well worked for spiders, so very unlikely that such a distinctive spider would have been overlooked. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Hard to justify reintroduction from abroad and unlikely to meet IUCN guidelines. New records may arise via accidental imports or ballooning juveniles for near continent |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | N/A |
| Justification: |
