The real Stylocheilus longicauda from eastern Atlantic

Hi Bill,

Here is a Stylocheilus longicauda from a floating rope at Madeira Island. You write that it is circumtropical but are there really records from the EASTERN Atlantic (that do not refer to S. striatus) ?

Cheers,
Peter

Hi Peter,

Rang's illustration of Aplysia citrina, which looks very like your photo, was from the "equatorial mid-Atlantic on floating Fucus" [see separate discussion]. I think that's the nearest find to the eastern Atlantic - but it may be worth checking Engel's paper which I don't have a copy of at home.

As this species is seldom reported, it is good to get another record - and one that certainly gets us closer to the eastern side of the Atlantic.

Best wishes,
