"Belongs to the genus Prostheceraeus. Although it looks very similar to Prostheceraeus bellostriatus, it probably is a new species.
Prostheceraeus bellostriatus has a characteristic orange marginal band and a median orange line which is missing in your specimen. Prostheceraeus belong to the polyclad family Euryleptidae."
