This small to medium species is known from two specimens, both under rocks on Kwajalein Atoll lagoon and pinnacle reefs. It could be a variety of Pseudoceros rubronanus. There is also some similarity to pseudocerotid sp. 8 in the Newman & Cannon (CD), but theirs has a black margin that ours lacks.
The one below looks as though it has just been feeding.
