Concerning message #16516:

Hello again,
I also thought it would probably be a H. villafranca but it looks a bit different from the one I sent earlier [message #16334 ].

Thanks,

Dear David,
I am glad to get your photos as it is helping to sort out - in  my mind, and I hope others - just what variations occur in these blue chromodorid species. The two animals you have sent photos of recently do look rather different, but I understand that the white line up the back of each rhinophore club is quite distinctive. Looking at the literature, it seems the experts have been confusing themselves - and each other - for more than 100 years, so don't feel bad about being confused. I am certainly still hesitant about identifying them. What I am sure we need, is interested amateurs like you photographing them, and with luck finding what their egg ribbons look like, what they eat, what colour forms mate with each other, etc. It will take time, but I never ignore the opinions of local enthusiasts with a long-term knowledge of their local fauna. Often when we get to the dissection stage, subtle external differences, which have been noticed by amateur naturalists, match internal anatomical differences.
Best wishes,
Bill Rudman
