In this paper, we validate the doubtful species status of E. guianae, with redescriptions of (supposedly lost) type and holotype males, and a first description of the female. Both sexes are measured and illustrated by pictures of habitus and copulatory organs. Seventeen new salticid species for French Guiana are also reported and a detailed catalogue of all salticid species from the Trinité National Nature Reserve is provided.

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 the mitochondrial COI rapidly evolving loci to confirm that both males and females belongs 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 ACCEPTED MANUSCRIPT / CLEAN COPY Gypogyna forceps Simon, 1900 and 12 COI sequences corresponding to four previously unsequenced Hypaeus species are added to GenBank.
