The present study reports the first record of Herviella mietta from the Andaman Sea, Indian Ocean, more precisely from the Andaman and Nicobar Islands, India. The species is identified by colour pattern, morphological characters and microscopic investigation of the radula and the lateral denticles. The important diagnostic characters are the carrot-shaped cerata that are predominantly black in colour, black pigment on the body, and 8–9 denticles on each side of the small central cusp of each tooth.
