At our BDS Dragonfly Conservation Group (DCG) meeting No.70 we agreed to accept Isoaeschna as the genus of Norfolk Hawker instead of Aeshna or Anaciaeschna or other name variants thereof. We didn't discuss isoceles but it seems this has to stay as-is, with the missing 's' between 'o' and 'c'.

Please review the following recommendations, that I am making based on searches at https://www.nhm.ac.uk/our-science/data/ … ies/search :
- Create genus Isoaeschna which I cannot find in UKSI. The genus is monospecific, having been devised for this species.
- Promote (TVK=NHMSYS0021775230) Isoaeschna isoceles to preferred and add the authority.
- Demote (TVK=NHMSYS0021009091) Anaciaeschna isoceles (Müller, 1767) to junior synonym.
- Demote (TVK=NHMSYS0021689820) Aeshna isoceles to junior synonym. This is on your Sandbox site (created back in Nov 2023 during the previous rename attempt) and on the NBN site but I cannot find it in the 'main' UKSI search and it appears never to have made it to iRecord in two years. I don't understand this. If necessary recreate it, as many people have been using this name form after Anaciaeschna was discredited.
- Decide on what should happen in UKSI to (orgKey=NBNORG0000109076) genus Anaciaeschna  - which still exists for foreign species but we no longer need in the UK. I'm guessing that it should remain in the system.

If I'm wrong about any of this please check back with me as I need to understand better!
Please let me know when this is live and I'll keep an eye open for it in iRecord. The changes will also need to reach NBN Atlas and GBIF in due course.
