Herviella, is a genus of about ten or so small species of aeolid, usually with black specks and often with a gold or orange band below the ceratal tip. The cerata are arranged in a series of sloping single rows down each side of the body. H. claror is characterised by the colour of the rhinophores - black speckling all over except for a translucent whitish region at the tip. The cerata have black speckling from the subterminal orange band down to the base. It has many similarities in colour to Herviella affinis, but in that species there is a distinct blackish band midway down the rhinophores and the cerata have a wide white region between the subterminal orange band and the black speckling which only occurs in the lower third.
