Abstract - A new species of Drypta Latreille, 1796 (Nesiodrypta Jeannel, 1949) from West Africa (Coleoptera Carabidae, Dryptinae) - Drypta (Nesiodrypta) negrettii n. sp. is described from West Africa, the third species belonging to the subgenus Nesiodrypta Jeannel, 1949 known so far from the continent. The habitus of the new species is illustrated and a map with the distributions of the known species from continental Africa is provided. It is a Drypta (Nesiodrypta) 16 mm long, its body with metallic greenish colour, the outer apical angle of elytra without a spine but with a tooth. It is distinguished from Drypta (Nesiodrypta) setigera Gerstaecker, 1867 by the elytra more convex, longer and less enlarged towards apex, their intervals less convex and less markedly punctate, their outer apical angle with a smaller tooth, the pronotum anteriorly and posteriorly less constricted, the ligula with a different shape of the dorsal spine, the body metallic greenish (instead of black or black with blue or purplish-blue metallic reflections in D. setigera). It is distinguished from Drypta (Nesiodrypta) posticespinosa (Basilewsky, 1960) mainly by the sutural and outer apical angles of elytra without a spine (with a spine at sutural and outer apical angles in D. posticespinosa) and the body metallic greenish instead of metallic blue.
