This common yellow species was named by Pruvot-Fol (1930) as a `n.sp. ou var.' from a pale yellow specimen from New Caledonia which she felt resembled the shape and size of the Mediterranean species A. leuckarti. It is most probable that the pale white specimen, tinged with yellow, from New Caledonia, that Risbec (1928) identified with A. leuckarti, is in fact a pale specimen of A. citrina. This speies is very common in eastern Australia and ranges in colour from pale, almost translucent, white, to a deep yellow depending on the colour of the sponge on which it is feeding.

Could you ID this little slug collected during the NOW-RAMP 2002 expedition to the Northwest Hawaiian Islands. Perhaps it's a Polycerid?

This is Aegires citrinus. Although it looks quite like a polycerid, it is most closely related to species of the genus Notodoris, which are course much larger. I have had a quick look at the literature and can't see a record from Hawaii but I may be wrong.

This is Aegires citrinus. It is another relatively common Indo-West Pacific species I should have had on the Forum.
