A rare species of bivalve clam Mactra aequisulcata G. B. Sowerby III (1894) reported for the first time from the Vengurla beach along the Sindhudurg coast of Maharashtra and nearby coastal stretches from the west coast of India. After comparing with the type illustration and malacological collections present in the National Zoological Collections of the Zoological Survey of India, it revealed that the species was found to be a new record to India which was although collected earlier and deposited, have been wrongly identified and not accorded a proper nomenclature. The presence of the prominent concentric growth line and the size of Mactra aequisulcata can be easily distinguished as the unique characters in the species, which make it differ from other closely related bivalves of the genus. A detailed description, illustration and geographical range extension of the species is presented in this paper. More authentication work from the historical collections may results in the addition to the molluscan inventory list of India
