Thirteen species of Lucinidae from continental shelf, slope and bathyal habitats off tropical West Africa are treated. Six genera and eight species are described as new: Lamylucina exgaini n. gen., n. sp. from the infralittoral, Tinalucina aequatorialis n. gen., n. sp. from the circalittoral W of Bioko (Fernando Poo) Island, Afrolucina discontinua n. gen., n. sp. from the lower shelf and upper slope (circalittoral), Lucinoma atalantae n. sp. from the bathyal of the Cape Verde Basin off Mauritania (2000 m), Lucinoma myriamae n. sp., Graecina karinae n. gen., n. sp. and Joellina dosiniformis n. gen., n. sp. from reducing sediments on the slope off northern Angola and Divaricella (Egracina) chavani n. sp. from the infralittoral zone. Furthermore, a new genus, Falsolucinoma n. gen. is introduced for Lucina leloeuffi Cosel, 1989. Two species of Anodontia Link, 1807, recently described, are re-included here. Lucinoma vestita (Dautzenberg & Fischer, 1906) from the upper slope (600 m) at Cape Verde Islands is rediscussed. Like many other West African species, the more littoral Afrolucina discontinua n. gen., n. sp. and Divaricella (E.) chavani n. sp. show distribution gaps along the West African coast and thus fall into the context of the hydrographical conditions of this coast.
