Re: Identity of Stiliger zosterae

Dear Bill,

I agree with your identification. However, I think Stiliger zosterae needs to be transferred to another genus, namely Hermaea. If you look closely at the rhinophores, you will see a short flap like the beginning of a bifid tip. This is seen in Aplysiopsis and Hermaea. Looking at Baba's original description of Stiliger zosterae, the radular teeth are short, stout, almost conical. When I first saw these teeth I guessed that this would be a diatom-feeder, like Hermaea vancouverensis, and I think this species is rather similar (though I have never seen it alive). So, to get a definite ID on this one, we will need to look at its radula.
