Some specimens of the genus
Onuphis Aud. et M-Edw. were collected on sandy bottoms in the Gulf of Follonica in Italy, and having the same characteristics they were considered a new species:
Onuphis falesia.
This new species differs from
Onuphis eremita (a similar species of the same habitat) in several features, e.g., the branchiae become bifid from the 20th-25th setiger to the last segments, and the tube encrusted with small stones and shell fragments.
Onuphis falesia is characterized, like many Onuphinae, by their wide variation in some features during different stages of development.
