This odd sea hare is known from a single specimen measuring about 15mm and found under a rock in a surge channel on Kwajalein's seaward reef. The visible shell and ruffled parapodia are reminiscent of Aplysia nigrocincta, but the shape of the head, including both pair of anterior tentacles, are very different. While A. nigrocincta is variable in color, we have not seen one colored like this specimen here in the Marshalls.
