Concerning message #17396:

Dear Bill,
From the picture it looks like there is a single brown stripe up the posterior side of each rhinophore. Wouldn't this exclude Halgerda brunneomaculata? I looked for another species with single brown lines up the back of the rhinophore, but they all seem to have orange tubercles at the vertex of the mantle ridges.

Cheers,
Phil

Dear Phil,
Yes I wondered about that, but I think the apparent single line is really just one of the two brown lines which run up each side of the rhinophore in typical H. brunneomaculata. The photo is a side view and I think we are seeing the right side of each rhinophore, rather than its back or posterior side.

Best wishes,
Bill Rudman
