The present study confirms the presence of a Sacoglossan (Mollusca) species, Lobiger serradifalci (Calcara, 1840), from India. The distribution of this species has not yet been documented in India. It has been reported from Turkey, Italy, France, Greece, Israel, and now, for the first time, from the western coast of India. L. serradifalci was discovered under green seaweeds in the lower intertidal zone. The species was found to remain hidden within various types of green seaweeds in the region. The study provides comprehensive details on its morphology, habitat, and taxonomy.
