The nudibranch Thordisa villosa is recorded for the first time from the west coast of India. It is the third known record of this species from India, observed after a long gap of 60 years. The last known record of this species from India was by Satyamurti (1952), from the Gulf of Mannar on the south-east coast. Specimens were collected in the intertidal rocky shores of Maharashtra and Gujarat. The occurrence of the species at three study sites confirms its range in this part of the Indian coastline.
