A new species of Hypaeus Simon 1900 is described from French Guiana based on both sexes, Hypaeus olympeae sp. nov. We employed morphological evidence, field observation, as well as the mitochondrial COI rapidly evolving loci to confirm that both males and females belong to the same species. Finally, nine species are newly recorded for the salticid fauna of French Guiana, Cyllodania fasciata (Caporicaco, 1954) syn. nov. is considered junior synonym of Gypogyna forceps Simon, 1900 and 12 COI sequences corresponding to four previously unsequenced Hypaeus species are added to GenBank.
