Abstract


A new subspecies of Phascolion pacificum Murina, 1957 is described from shallow waters (15–20 m deep) off Malvan and Ratnagiri in India. Phascolion pacificum denticulatum ssp. nov. is characterized by the presence of a prominent tooth-like projection in the median part of the free border of the holdfast papillae. This finding represents the first record of any Phascolion species for all the Indian coasts.
