A new species of Platepistoma Rathbun, 1906 (Decapoda: Brachyura: Cancridae) from deep water off South Africa

Platepistoma seani sp. nov. is described from deep water off KwaZulu-Natal Province, South Africa. It can be separated from its nearest relative, Platepistoma guezei (Crosnier, 1976), by its thicker setal covering that completely hides the anterolateral teeth from dorsal view, less well defined carapace regions, more spinous anterolateral and posterolateral carapace margins, sparser but more prominent dorsal carapace spines, more prominent spines on the carpus of the cheliped, and a relatively narrower male telson.
