Hi Bill

Could you tell me the taxonomic status of Hermissenda crassicornis. I believe the genus is now Phidiana and would be grateful if you could confirm this.

All the best,

Dear Maria,
Your question gives me an opportunity to use a couple of Daniel Geiger's great photos. He has kindly sent me a set of photos from California and Europe which I will be able to use to illustrate questions and discussion topics.

I don't think there are any good characters separating Hermissenda from Phidiana but people tend to become attached to the names of their common animals. Most Californian literature still calls the animal Hermissenda crassicornis.

Could we have some guidance from the Californian experts? Are there good reasons for persisting with the name Hermissenda? Can you give me a recent reference?

Thanks,
Bill Rudman
