Remarks. Mulinia cleryana , dedicated to M. Cléry, is a valid species. The synonym list includes Mactra guadelupensis Récluz, 1852 ( Figs. 9 View FIGURE 9 A–D), Mulinea portoricensis Shuttleworth, 1856 ( Figs. 9 View FIGURE 9 E–F), Mactra carinulata Deshayes in Reeve, 1854, Gnathodon cantrainei Sowerby in Reeve, 1873 and Mulinia branneri Dall, 1901 ( Figs. 9 View FIGURE 9 G–K). The type materials of all these nominal species were examined and their status confirmed. Conrad (1868) mentioned Mactra grandis Deshayes & Milne-Edwards, 1835 (not Gmelin, 1791) and Mactra lamarckii Philippi, 1846 as synonyms of M. cleryana . However, the examined original illustrations of both species differ clearly from the type of d’Orbigny's species. There exists no type material of Mactra grandis and Mactra lamarckii . The first one is an illustration published by Lamarck in Bruguière et al. in the “Encyclopédie Méthodique” (1797, pl. 253, Fig. 1 View FIGURE 1 a–b); and cited later by Deshayes & Milne-Edwards (1835) making erroneously reference to Mactra grandis Gmelin, 1791 . Later, Philippi (1846) introduced a new name for the illustration given by Lamarck. The two nominal taxa should not be considered synonymous with M. cleryana .

Although the examination of type material confirms the synonymy list, preliminary results from geometric morphometric studies suggest a shell variation along the specimens examined. This variation, currently in process of study suggest the presence of a Caribbean and a Brazilian morphotype. Finally the shell characters observed in Mulinia cleryana separate this species from the superficially similar Mactra isabelleana d´Orbigny, 1846. The main differences are the absence of an external ligament, smaller shell length and the posterior keel-like carina in the Brazilian species.
