ABSTRACT. Libystes senckenberg sp.n. is described on the basis of the specimen long time known as Libystes aff. nitidus from the Persian Gulf. It differs from L. nitidus A. Milne-Edwards, 1867 and other Libystes species by a short and stout gonopod 1, with widened tip and the presence of prominences on the anterolateral margin. A peculiar characteristic of the species is incompletely symmetrized chelipeds. Libystes senckenberg sp.n. was found also in the southern Red Sea. Specimens from the South China Sea are tentatively assigned to the new species although they show some differences in carapace morphology.

KEY WORDS: biodiversity, taxonomy, true crabs, new species.
